I did the rear brakes on my 75 Century this past weekend and had something strange happen, and I was just wondering if anyone else has ever experienced it before. When I got the new wheel cylinders I checked them over, and they looked and operated good. When I installed the wheel cylinders they would not move. I had to loosen off the bolts, push the cups together and then tighten the bolts again. This appeared to fix the problem at first, but the pedal just does not feel right. Feels stiff as heck and I am wondering if the wheel cylinders were made wrong. Anyone else have a similar experience?
Inside the wheel cylinder is a spring that pushes the cups out. So sometimes the cups need to be squeezed and pushed into the cylinders to install them. If you don't, the cups might interfere with the backing plate and get stuck against it. Once installed and with the shoes and hardware back together, you should be able to push the cups in with a screwdriver easily. When you say he pedal doesn't feel right, what exactly does that mean? Is it spongy? How did you bleed them?
The pedal just feels hard and does not like to move. Before the brake job the pedal moved fine, but the wheel cylinders were shot and leaking and no fluid was in the master cylinder. The master cylinder was replaced as a precaution. As for brake bleeding, worked my way around the car while someone pumped up the brakes.
Possibility that the rear flex hose may be clogged, but if the rear wheel cylinders squirted out fluid during the bleeding, that's unlikely. The only other change was the master right? Maybe you can try bench bleeding the old master since it still may be good and see if there is any change in the pedalo No: Or if you get a different problem. If anything, the old master would make the pedal go to the floor. Old masters don't like it when pedals get pushed to the floor
The car does stop, but only moving around in drive way right now. MC was bench bleed and seemed fine. Unfortunately the old master is gone to the scrap yard already.
