Faulty ones were bendix. I think its partically my fault b/c when I did the brakes one time I took both sides off at the same time (dont do that, pistons came come out) and the piston kinda came outta the one side..

IIRC the new ones are bendix too, but I havent had any issues, well other than them rusting to hell. I think perhaps though that the rear wheel cylinders partically caused it as I drove ALOT of miles with the brakes like that b/c bleeding did nothing we thought it was a fluke..

Why do all parts from the parts store come uncoated? I think I am gonna take the wheels off when it warms up, take my grinder and go to town on them with a wire wheel and paint them.
