yes, thanks! i hadn't thought to look on Summit. yeah the EBC stuff is pricey.

i picked the tallest pedal/highest ratio i could fit, that's not adjustable. it is on the low side. the master is probably the way to go.

yes, thanks! alas, most of the MCs in that pro-touring site are no longer available on RockAuto, which i take to mean they're all too old to use if i were to find one elsewhere. i got one of those MANUFACTURER CLOSEOUT MCs, it was so old that it wouldn't bleed, the rubbers all went bad (that story, again and again). since it's in the floor it needs to have a metal resevoir and cover.

the one i'm using now, some 70 ford pickup, i got new, but is now no longer available. i bleed brakes annually and i tend to haver them last a long time, but it means on-road failure could be very unpleasant. i like to plan ahead.

there was one in there that's current-new that i hadn't seen before. i may go look for one before need.

You could go remote reservoir with a newer MC. Hoses could get damaged, but you can use a braided steel hose to a reservoir on the firewall. A gravel shield of some sort might be the way to go and use a plastic on the MC reservoir...

IowaTom -- you DO NOT want to bend the steering arms!! That changes steering geometry, specifically the Ackerman Angle. The big brake kit should fit big Ramblers, but not the 58-63 American (or 50-55 Nash Rambler).  You could get by with bending the arms slightly, maybe 1/4" out, as the Ackerman Angle isn't perfect, but much more (in either direction) and you mess up the turning radius a lot. I made arms for my 63 Classic and don't have the angle just right, but tires only scrub a bit when turned full lock, most noticeable when backing up (geometry changes a bit when backing...).  You really don't need the bigger brakes for the light weight American, even with a V-8 parked in front. A typical small block (anyone's) only weighs about 50# more than the old 195.6 hunk of iron... about the same if you go aluminum heads, and a newer aluminum block V-8 is probably a bit less...

Thanks, Frank!
Know what you mean about bending steering arms and I have no intention of doing so.
Tomorrow (Weds) I plan to tow-dolly the ol' girl home and examine the front steering setup vs. what's in the Scarebird photos for discs.

Late '70s/early '80s Mustang/Cougar/Fairmont w/ 4/6cyl. and manual brakes used a 7/8" bore.
e.g. Cardone 13-1764 ... $20 at CarID ... but available lots of places. Dorman and others have equivalents if you don't like Cardone.
7/8" bore master cylinder
listing for '80s Mustang - master w/right-side ports should be 7/8" bore
Cardone spec on 13-1764:
- disc/drum ... remove residual valve if equipped and running disc/disc ... but likely need a 2 psi residual valve in both lines if master is below calipers
- 7/8" bore
- 1/2"-20 and 7/16"-24 ports

Note the smaller bore will be much more sensitive to any air, so make sure to bench bleed fully and ensure full stroke is enough volume for your calipers. May also need to adjust pedal position (pushrod length) to suit increased stroke

Hope this helps,RD

YES. THAT HELPS. A LOT. !

man i thought my search fu was decent, but i am in awe. last night i spent a good 45 min on summit, and again on rockauto.  did you start with the '80 mustang' search? 

funny that for once, the best candidate is the cheapest. i'm OK with cardone. it's new manufacture too. i hope 'new' wasn't 1985, but for $20 it's a worthy gamble.

the ports are on the right side too.


(playing around with summit's search... i knew that the parametric fields don't appear until the number of items is either small enough or categorically narrow enough. but i never considered selecting 'engine size' to narrow the search. that makes 'bore diameter' appear/disappear. aargh. without, > 6000 matches, no parameters. with > 2000 with parameters. go figure.)

THANKS!

Hi Tomj,

I actually started with the Cardone master cylinder catalogue, which is about 180 pages. It lists a few thousand part numbers with many pages of illustrations. Near the end of the catalogue they group masters by bore size. There are several pages of masters with 7/8" bore, but only a few have integral reservoir and SAE ports. Comparing with photos gave a good guess at something that would work.

Once I had a part number, a simple search found the application details for model, year, etc.(CARiD is a good site for this). Then can easily search your favourite retailer by make, model, year & application to get matching parts.

Expect porting, bolt spacing and pilot may not match exactly, but since yours is a custom install with another Ford master, may get lucky.

Hope this helps,RD

Most AMCs use a 1" bore MC. The 7/8" bore will move a little less fluid (pedal travel will increase slightly) at a higher pressure than a 1" bore. Should be fine though.

I'm not so sure the big brake kit won't fit your Rambler -- that's the big car. You'd have to try it. The standard kit fits with no issues though, and should be more than enough even for a V-8 big car. Will be better than the drums that came with the V-8 cars, definitely better than the smaller drums on the six!
