I have a 68 Javelin SST that I am converting to power disc brakes from power drum brakes. I got the power disc booster and master cylinder but now I need the disc brake booster to firewall mounting bracket. Does anyone know where I can find one, is there one that fits other manufacturers that I can use?

Put an ad in the 'Wanted' section. I'm sure someone has one that they'd sell.

I converted power drums to power discs on the White70.
I had to place spacers between the booster and the bracket, roughly 1/2 inch thick. I think that's what the factory did as well. Experts? Add to this please ? Am I correct? |

It's more than just the booster spacers. The linkage is different between the drum and disc boosters. Disc top, drum bottom. At least in '70.

That's what I'm having trouble with right now is that linkage I think mine is seized where the brake pedal rod goes through the firewall and connect to the linkage absolutely no movement there. First post not sure how to put a picture up

If your linkage is seized up, this may be a solution depending on what you have. http://theamcforum.com/forum/master-cylinder-booster-pivot_topic86893_post775058.html?KW=#775058 |

I bought the brake booster at AutoZone they had it shipped to me in 2 days pretty much an exact duplicate of what I had ran into the pivot pin problem when I took it apart the brake booster was $91. I had vacuum problems here it was the vacuum booster wooden pool above 4 in of vacuum. I thought it was the cam it still may be but I bought a little vacuum pump from Summit which puts out 16 in vacuum so brake should work well

I successfully converted the White70JavelinSST from drum to disc brake booster and brakes using only the parts from the drum brake bracket and linkage including the pushrod that came with the disc booster. It does put the pedal in a bit different spot., but its still a completely workable situation. I like the brake pedal closer to the same plane as the throttle, I can side foot the throttle and brake simultaneously for downshifting and braking together. The brake pedal does not bottom out on the floor of the car dead engine or engine live. Of course I cannot remember all the details as I did this over ten years ago. So that in itself says it works, I put about 1500 to 2000 miles a year on the car. |
