2002 F body brake pressure
 

I know this has been beat to death subject, but how much brake pressure do you need to hold a 2002 f body on the starting line. We have 4 piston aerospace on the front 4 piston strange on the rear. After 3 pumps we have 1000 psi on the rear. It seems to wants to pickup the front end and then slides the front tires. Do you think moving the rod up on the brake pedal would get more brake pressure? Or a larger bore on the master cly.? Thanks Tom

Couple of questions here. Which end is plumbed to which end of master cylinder? And where is the pressure gauge plumbed into?

Rear brakes are on the front of the master and the pressure is taken at the bleeder on the rear caliper. The car when we got it had braided hose, we switched it to hard line. The car has good pedal and stopping it is no problem. Tom

Have you tried more pressure? Aerospace sells a pad that holds better, I got 400 rpm. I don’t know if the will fit the calipers you have, compare to your front pads. Some people do run dual rear calipers.

1000 psi should be enough to hold it. Smaller bore master cylinder and moving the rod up will make the pedal easier and should allow more pressure.

Most of the probable issues have been mentioned .
Excessive hose length , bore size ect. Pedal ratio is very important , unless you're an Olympic weight lifter .
Using a larger bore will give more volume but LESS pressure with the same pedal ratio and travel .
With a 6 to 1 pedal ratio and a M/C bore of 1 1/16 to 1 3/32" you should be hitting at least 850-900 # on the first pedal hit .
Have someone pump the pedal while you watch the calipers as they are applied and watch and feel for deflection or movement in the caliper itself and also the rotor.
Proper alignment is extremely important with after market race brakes due to the light weight of the mounting brackets and light weight rotors .
I've seen many brake issues cause by misaligned rear housing ends . Its especially a problem on older GM housing ends that are usually heavily rusted and warped.
Any movement here will make it harder for the brakes to get a full ,positive hold .

Cooter what do you master cyl do yo use. Thanks

How loose is the convertor and what rpm are you trying to reach? What gear in trans and convertor? How much power does engine make?

Reach out to Brian Anderson from South Dakota, I know he has been able to hold almost 5,000 rpm on the starting line with his LS1 Camaro lately. I believe Aerospace front brakes and TBM on the rear.
