I love what your doing.
I just wish you could drive the car with your changes and see how it works, and start tuning and competing with it.

Thanks! I do too, though it is to be a daily driver, ever when I get to completing it.

Hind sight, I should have left my perfectly good running engine and tranny alone, so I could test each upgrade and feel happier knowing there are real improvements over just esthetics. There are some things that bug me, mainly using obvious non 70's brakes, wheels, alternator and engine accessories. Not that i wanted all factory components, just wanted to keep things in the period, or be sneaky with newer tech to be not so noticeable.

Oddly enough the engine compartment will give away too much of the details once you get looking around at new components.

I may post a light weight upper and lower control arm reinforcement mod, which is a variation to most other mods pertaining to strengthening. Since I have a few things needing welded up, that part will be added to my list. Unfortunately welding is something I can't do, at least for now.

Well, I did a wee test run with stiffness after some elongating the strut rod holes on the poly bushings.

Found a few wee issues. One is I may need to obtain a rubber bushing kit that includes the steel cups that fit between the bracket and bushing. It is to keep the poly bushings in place to lock against the bracket. Will end up trimming off the thin ring that was left from my modification, as the locating ring was sturdy enough before the modification.

Still will need to order Teflon washers, as the poly grabs the metal compression washers.

Also I may need to touch up the cups slightly as I did not use as much compression as I thought. So it is to allow just a wee less pressure against the ball.

All in all it did free up the stiffness when pivoted, and kept the rod in check to its proper angle of pivot. Floating pivot is no longer.

Also it works best with concave facing away from the bushings on both ends.

Though I think rounding the face a wee bit will assist with correcting enough to use the factory setup with concave flipped on one side only.

I will test further when I have time.

As a wee update... looks like a reshaping of the bushing face to the concave compression washer. Too bad the washer is not fully concave down to the hole. I cleaned up one washer and greased up the bushings face for the concave fitment against it. After a few movements of the rod by hand, it proved it needs the Teflon washers and the flat edge rounded. Looks like concave faced washers are the only way to go with this setup. It won't make it worse just keep things in proper function. Will also recommend using the metal seats for rubber bushings. Some kits have them others don't. Though I am not sure if there is enough clearance for the ball with them as of yet. May not be able to use them.

Almost done... more updates near the end of my page entry, to my Delrin poly bushing mod. With very good results.

Please note, the pictures were set by improper orientation of bracket assembly for better image clarity of components.

Modding SN95 Hydroboost, Braking and Steering


Parts used: (98-04 can be used)

95 Corsica hydraulic clutch (aluminum body with Russell fitting)
96 Police Caprice / Impala SS - GM big bore front calipers (Mounted - Rear)

If using a V8 Explorer pump use the line below.
07 F350 V10 Super Duty - Pump to Hydroboost - 39.25" hydraulic line (Edelmann 80440) May have to bend the pump fitting a wee more to fit.

If using Mustang GT pump use line below, may be a wee long, and it's the only line with a proper fitting for the pump.
00 Mustang GT - Pump to Hydroboost - 57" Hydraulic line (Edelmann 91974)

00 Mustang V6 - Hydroboost to R&P - hydraulic line (Edelmann 91986)
Less costly, and fits for the custom application in our cars.
02 Explorer - 12" 4x4 rotors (Mounted - Rear)
02 F150 Master Cylinder Reservoir
01-04 Cobra - 13" rotors (Mounted - Front)
03/04 Cobra - Front disc calipers /w brackets (2 complete sets for dual setup)
04 Mustang GT/Cobra - Hydroboost unit
15 E350 SD - Remote power steering reservoir (3 port)
Additional reference for completing a full Ford setup: Installing a C-III pump

WARNING

Mixing parts from various years and models can make selecting over the counter parts to service difficult to properly match.

EXAMPLE: Pre 05 CIII power steering pumps mostly use a 16mm Swivel O-ring (type III). Pre 05 V8 Mustangs used a standard 16mm O-ring fitting at the pump output, which limits line compatibility options down to just V8 Mustang applications. No other pump to Hydroboost line can be used as a direct fit. So, aftermarket fittings and lines will have to be done if the oem line cannot fit within the engine bay.

Another more limiting issue is the Hydroboost unit. Again Ford made the 89 to 2004 V8 Mustang limited to just V8 Mustang parts. The Hydroboost for V8 Mustangs has an 18mm type III input port, which makes it mostly limited to the V8 Mustang pump to Hydroboost hydraulic line, until...

Touched by the Super Duty V10 gods

Since I chose to use a pre 02 V8 Explorer power steering pump in my custom serpentine setup, based on Ford modular design, I created a monster. Well if it were not for a limited run of F250/F350 V10 Super Duty trucks built between 05 and 07, I would be stuck using aftermarket fittings and lines. So, thank you Ford for finally making Super Duty trucks use 18mm Type III fittings. The only issue is a slightly more bend at the pump end of the line to make the fit work, as the line is almost 20 inches shorter than the extra long V8 Mustang line.

Removing Mounting Plate:

It is fairly simple, use a C-clip plier to remove the large C-clip that is used for safety precautions.

Once the C-clip is removed, lay the Hydroboost flat so that the plate is set against the ground or work bench. Take a punch and hammer and knock a corner edge of the large lock nut. You may need to flip and do another side a few times in rotation. The nut will undo it's self from locking against the plate, and spin free for removal.

All removed parts are shown in the picture below.




Removing Pedal Apply Rod:

Once the rubber boot is removed, cut off the staked section flush with a Dremel tool or hack saw, so that the cup for the ball end of the rod has a smooth and equally formed side wall. The cut off area should be a ring almost as wide as the remaining cup.

Once done, the actuating rod will fall out of the apply piston's cup. Clean up the cut edges so that your original apply rod fits smoothly.


Modding original brake apply rod




I cut down the rod so it is 7/8" longer than the factory Mustang rod (About 2-3/8" from eye inner radius to tip), which makes the replacement about 3-1/4" long from tip to Inner radius of the eye. Once cut, rounding for fitment and verification of peddle placement and clearance will need to be done. The stock brake pedal and my GM pedal both are just above to a 2:1 ratio on the apply rod. So, about 1" apply rod travel is close to 2.1250" of pedal travel.


Brake Line Connections:

I will leave ports alone and lines setup like stock 04 Mustang setup, minus the proportioning valve.

The hydraulic clutch master cylinder will engage the secondary front disc calipers independently if the brake pedal is not engaged, else will work as a slave to the brake pedal as one engagement.

An in line brake bias valve on the rear brake line, and a few other brake hardware enhancements will be used as things are tied into place.


Brake Fluid Reservoir Mods:

Easy mod on any Ford master cylinder reservoir. Cut off the wee tabs that are 180° apart located inside the fill neck. They are to keep the float body in place when upside down. Once removed the barrel float body will drop out. Will make access for cleaning out much easier. For me it will allow for more capacity to leave it out. I made even more capacity by cutting out the float cylinder top half. A heated Exacto knife cuts it out in 1/4 sections.

I also removed the low fluid sensor switch at the bottom, since it is not used.

The parts I removed for modification are shown below.



This is the inside of fill chamber, with the low fluid float and the upper half of the cylinder removed.



Notice there are many chambers to keep fluid from sloshing about and sending false signals by the sensor. Opening up the sensor area can assist in allowing more fluid reserve, and quicker response to the demands of the braking system in track use.


Master Cylinder Mods:

Found I will have to take the master cylinder off and disassemble, to modify the rear brake to function like the front brake section.

The reservoir port is an area of needed change in function, so enlargement of the fluid feed hole for the rear port is required. Notice that the front brake bleed has a pin to keep the assembly in place when the C-clip is removed. These master cylinder bodies are used in just about every model car and truck for the years produced, some have a bleed hole for the rear brake pressure. After further review, the pin is a semi loose fit, so I guess the wee bleed hole is to equalise the differences between the pressure lost by the diameter of the semi loose fitting pin.

Here is a picture of the internal components and pin.



Note: I am going with minimal mods to the master cylinder, since they can be very effective in allowing large bore disc brakes to function on the rear wheels along with dual caliper fronts. I have reversed the seal (OEM placement, has a seal not facing forward in the bore) on the front piston so pressure from the larger throw for the rear piston will bleed into the front, to equalise some of the differences in displacement during engagement. What I am doing is removing most of the delay in independent function. As long as I keep the springs in place there will be some independent action between the front and rear pistons. Having rear engagement be quickly applied for stock purposes, will defeat some of the requirements of large disc calipers at the rear.

Here are the two feed ports of the master cylinder. To the right notice the pin in place, and the differences between the feed holes between the two ports.



For now, if repairing a limited run master cylinder on late model cars, is not so easy, as seals are not being available to parts sources. If keeping factory correct with markings and such, buying a rebuilt unit with a lifetime warranty for swapping seals would be your only option for now.

This is a low milage 04 Mustang GT/Cobra master cylinder, so everything should be like new inside. A tare down will verify and allow for cleanliness, especially when using a used item.


Hydroboost Mounting:

I got around installing the Hydroboost to the firewall as a direct fit through the factory hole for the OEM master cylinder. To mount, you must remove the brake booster, master cylinder nuts on the right side (engine bay), and remove the studs from under the dash and reverse the installation of the stud assembly and mount from the engine side and from the dash install the nuts. Then install the Hydroboost and use the large lock nut from under the dash.

Here is the bugger that needs to be remounted on the engine side of the firewall.



After further inspection, you must grind a radius in the center of the long side edge facing the Hydroboost unit. If you don't, the Hydroboost will install crooked.

Below are pictures of clearance and looks. You will need to replace the Mustang reservoir with an Explorer / Ranger reservoir, since the Hydroboost is level not tilted up by the mounting on a Mustang.





The nice thing is no mods needed to mount, and you save time and money with a custom modders adapter plate.

For some, they may not find it fun to install or remove, as it requires dropping the steering column and pedal assembly. Which may require dash removal. This is because of the large locking retaining nut and it's clearance between the pedal and steering column mounting bracket. Since I am building a car from the ground up, this is not an issue. May look into modding the locking mounting nut, by welding on an extension to the nut, if clearances allow.


Pictures and further information to come.

I have updated my changes, and cleaned up a few errors, along with some assumptions on my recent entry. Since many views have been done since I first posted yesterday.

After a bit of looking at ratios, volume and function of the pistons on the Ford and Chevy master cylinder's, I realised simple mods 1st and if need be, some changes can be done to sort out any issues.

At least the layout is coming along and easy to follow.

To give an idea of what is going on so far... 2-1/4" between springs and rim edge, though the springs are about 1" further out than stock, for my mods with rear mounting, thus he ability to use 10" wide 2015 Mustang GT wheels, but... there will be some mods needed to the sheet metal as expected.

One is removal of the trim lip and rolling the contour of the wheel opening out at the top inch or so, just enough for clearance for maximum wheel travel. Then finish it off with blending the body to fill in the gaps at the lower front and rear for that 70's fat Vette look. It Is a wee more flair than I expected, but I forgot I moved the spring pads out so much to compare fit with body. I put too much into clearance when selecting, so this issue was a given once that had settled in my brain.

I assume the same changes will be for the front fenders as well.

The picture below shows how far I have with the rim edge and body, though it is off from viewed angle, so the wheel looks to protrude more than what it is. The rim will rub the lip for the trim, but it will require another 1.2500" more bulge for covering the tire without rub. I can deal with that, just expecting anymore, would be less than desired for my setup.



12" rear discs look a wee small now. Ha!



2-1/4" free clearance for tires. Yes i used trailer spring plates and U-bolts. Wanted the most secure and stout setup possible for maximum stability the plates are so much bigger that they flatten put the spring arc when clamped down.



For cheap wheels they are well packaged, never had low to mid priced new wheels shipped so well. Removed the plastic they were bagged in, to show the soft fiber liner and nylon snap on lip protector. The only cheap part of the packaging is the box. Either double box or use a heavier box, and it would be considered a premium wheel. These boxes tear easy at the handle holes.

Wheel construction seems better than expected. Knowing they are pressure molded and heat treated before finishing, but it seems the paint is powder coated. Or something like it, as it seems to be bonded to the aluminum. Thin but durable. I purposely rolled the edge at the back lip on the cement, and it did not scratch up like the factory Ford Racing wheels I had. The whole wheel was done in matte black, and the face was machined in the final process.

i have some surplus teflon sheet, about 1/8" thick, and make washers from it with a hole saw. big hole saw first (OD) then small hole saw or Greenlee punch for the center (ID).

did the same with some Micarta sheet for suspension spacers.

Hi, yep I figured one can do their own custom washer. I found a fairly close fit for the washers at a very low price, just did not realise how stiff they were, and how well and much they would compress the assembly. At least shaving them was for the most part all I had to do, outside of a wee ream of the center to fit over the sleeve.

That's where having a fully-equipped wood shop upstairs can be an advantage - I can work with almost any material, from pine to oak to maple to plexiglas to laminate to teflon chunks or sheets to brass, zinc (I cut my zinc bars on the table saw- sliced them to the thickness I needed for use with plating) aluminum stock, whatever. I have a good variety of blades for the band saw and scroll saw, multiple hole saws including an adjustable size hole saw, various sanders - disk and belt, etc.
I often have to clean up almost as many metal or plastic shavings and dusts as I do wood.
