Rear drum cylinder leak?

I always rebuild the original ones. That way, you have sure nuff American made high quality metal wheel cylinders. 99 times out of 100, they can be rebuilt.

It's not rocket science, either. Two rubber boots, two rubber pistons, two metal pistons and a spring in the center.

All they usually ever need is slight honing with a brake wheel cylinder hone to clean them up.

I liken replacing factory American made wheel cylinders with imported ones to replacing good, stainless steel wiper blades with BS plastic ones. See it done every single day.

Course, wiper blades ain't as important as brakes, but you get my point.

Not to mention, wheel cylinder kits are like 3 bucks.

Remember, there's a reason complete wheel cylinders are available around 10 bucks each. They are cheap crap.
