Wilwood Brake Peddle - Proper Adjustment

[Tommy]

landmass,
There is more to getting the front/rear brake balance correct than just the pedal bias adjustment. It will vary from car to car depending on the size of the front and rear master cylinders and the calipers and the rotors. Pressure alone will not tell the entire story. .... It sounds like you didn't choose and install your brake components, so I suggest you go over the entire setup as if you were installing it yourself for the first time. For example, you'll want the front brakes to do most of the work, so in most cases the pedal bias should push harder on the front master cylinder AND the pushrod to the front master cylinder should be adjusted longer than the rear to allow for full throw under hard braking. The Wilwood website info should cover this type of information.

The rule of thumb is that you want the front brakes to lock up before the rear. Since the front tires carry more down force during heavy braking, they will do most of the stopping when you need it most. By having the front brakes lock up first, you know you're getting all you can from the most effective tires, and you reduce the likelihood that the rear tires will skid you into a spin. For these reason, I'd start with settings that strongly favor the front brakes doing most of the work. Then, as was described above, find a safe place to test the brakes and find out which ones are locking up first. Make adjustments and repeat the tests until you're getting as much from the rear as you can, but the fronts still lock up first.

If you're not comfortable doing this sort of work yourself, try to find a race shop or hot rod shop to do the work. Normal mechanics don't typically do this kind of thing.
