Brakes

Well folks I'm back with another issue. I think it id s bad wheel cylinder on the right drum. From my knowledge, the pistons hold the tops of the shoes in place. Am I right or am I wrong? New shoes and springs have been replaced but when I took the car to go out to the zoo, I heard the shoes grind yet again. Is this because the pistons in the wheel cylinder are still pushed in and do they need to be pushed out to hold the shoes in place better?

Drums are touchy but they are very basic. The things that holds the pads in place are the springs. The cylinder is what pushes them out.

If your having a grinding noise I want to say that the shoes aren't correct for the car. When I purchase shoes I place them directly in the drum to see if they contour the same as the drum itself. One time I never caught it, and replaced the pads 3 times and replaced every spring inside there. Come to find that the contour wasn't right and the upper and lower part of the shoe was grinding into the drum! LOL I was so mad but dumbfounded that I didn't bother to check.

If you suspect that the shoes are being pushed and held them you would hear it at all times, they will retract. Your only issue is while braking. Take off the drum and inspect the wear on the shoe. If you only have wear on the top edge and bottom edge, well sir you found your problem.

Thanks. Come to find out it was the backing plate that has rusted to be heck causing the noise. At least the car has new shoes and wheel cylinders on it

Usually I sand down the area the shoes ride on then put lube.

It helps. Glad you figured it out
