Brake problem

[kdanner]

Internal master cylinder leak only once the rear circuit gets to that pressure maybe?

Maybe internal degradation of any rubber lines you may have? I heard that they can bunch up and cause internal restriction or blockage as they age.

I've had some trouble with holding the car on the line with OEM disc/drums lately and this thread made me realize that the brake "T" assembly on the rear end housing is the only rubber hose I still have in the system. M/C has been changed and all the other lines are solid or braided.

I put a higher priority on the rear brakes because harnessing the torque there will accomplish more than at the front. The best front brakes still only have a pair of skinny front runners trying to hold the car and can easily slide.

I'm changing master cylinder and rubber hoses going to rear brakes first.

Did you find the problem?

Yes master cylinder

Did you happen to teardown the old master cylinder to figure out where the leak occurred ?

So the MC wasn't sending as much pressure to the rear as the frt.? Are you running a replacement Mopar MC? I've got a Dorman Mopar MC on mine which is an 85 Camaro. Only thing about it I didn't like was the shallow bore where the rod goes into the piston. I modified my pedal quadrant to support the rod so it could never fall out. I've got a plate on the firewall but I do notice the firewall flexes a little too.
