Adding a booster

frankym · #1 (**permalink**) 10-30-2001, 12:06 PM

I have a set of dual master cylinders which I have been told my somebody that knows a lot about racing applications that I should really move to a smaller set of masters because the pressure needed to apply the brakes is enormous. He also said that it would give the brake pedals longer travel which I understand. However, I like the short travel but cannot really brake for any kind of aggressive driving. Also, my clutch is about as stiff as can be, some of my driving guests say that they just cannot drive it because the amount of foot pressure required to get the clutch all the way to the floor is unbearable. Is it possible to add a booster for both hydraulic systems, any reccommendations would be helpful.

well I have done afew other booster projects and the brakes arent to bad. you will need a booster setup, with master cylinder around 200.00 if you look hard you can find one that will match your brake pedal and then just reroute the brake lines but you will need a porportion valves. and of course hook up a vacuum source. fitting a booster into your space and running brake line are the only hard parts. the clutch i dont know of any boosters for clutch, they usually dont need them so i would check and see why this is so firm. clutch basket or some other componet may be to blame what type of setup do you have for a transmission.

later MIke

thanks for the advice, the clutch is a centerforce @11 inch with multiple spline setup, trans is a 4 spd BW T-10 sideloader, rear is 373. clutch master has a small reservoir with wildwood pull style slave

Frankym,

As far as the brakes go, if you don't have an 11" rotor, now is the time to upgrade. Change you're brake master cylinders to 5/8" bores. You won't notice much difference at all in pedal travel. Upgrade to a good brake pad like Performance Friction or Carbotec. You don't need to add a booster. This setup is for the Granda single piston caliper. If your using Corvette suspension I'm not sure about the master cylinder bore size.

The first clutch I put in my car was also impossible for anyone to press except me. And then it made my left leg ache after a lot of driving. I originally had a RAM long fork ford pressure plate which was much too stiff. I changed to a Centerforce dual friction
diaphram clutch and now the clutch is a breeze and still hooks up great.

This isn't my best guess. I've been through all this and I know this works.

Good Luck,
Jerry
