Brake help

SlowJoe · 02-24-2007, 05:10 PM

We are working on a 91 LX with a 429 in it. We went with a manual brake master cylider.It still has the stock 4cyl brakes up front, that will change!It has the thunderbird turbocoupe rears that are disk.We need to know how to get some good brakes on this thing bad.But it has to stay with a small master cylider because of the BBF.

Booster should be ok, just need a bigger master cylider. The bore sizes is larger on the disc brake mustang compared to the drum one. One out of a svo would be just right. You need the valve thing for it to. What is it call.

Autozone is a cheap place to get one and new. I have a brake booster off and explorer that barly fit with new holes and alittle hammer work. Smooth brake with half the foot.

Look for a pinto master brake cylinder. They may be small enough to fit your tight spot.

You could try and run an SVO M/C however because the piston bore is so large, it may not fit the manual M/C adaptor plate.
This is the problem I ran into years ago, however I was using a Ford manual M/C plate, not an aftermarket one.

Secondly, since the bore size of the SVO M/C is so large, pedal effort might be very high, not sure.

Also what front brakes are you planning on running?
The caliper piston bore size and amount of fluid you will be trying to move really dictates how big your M/C bore size must be.

I suggest you guys figure out
what fron calipers / rotors you want to use, then go from there.
