Re: 2002 F body brake pressure
 

Tom My car was plumbed backwards initially causing excess pressure on the rear brakes. I bent the backing plates before I changed the lines around. Mine has front disc with drum rear. Hard to find good help

Thanks for all the help. Tom

Re: 2002 F body brake pressure
 

When we ran an automatic, we had dual rear caliper Mark Williams brakes (and MW in front as well) and would put about 750psi of brake pressure (on a gauge in the car) - and that would hold 43-4500rpm without issue. On the 2-step the car wouldn't move at all either in the front or the rear no matter how loose we had the front or rear shocks. The brakes held the car rock solid. I'm not sure about the master cylinder, but I assume it was whatever Mike Pustelny from MPR Race Cars would suggest.

Was it a step bore master cylinder? If the master cylinder has the same size bore for both sections how can it have more pressure at one port? Did you measure the frt. and back pressure with a gauge?
