I am confused again. I replaced the rear drum shoes a few months ago. I have also replaced the drums, springs and hardware at that time. I just replaced both rear brake piston assemblies. I have been having trouble with one side since the first repair. It gradually tightens up so the brakes drag. The other side is always OK. If the new drum is out-of-round, would it do this? I have never felt fully comfortable with aftermarket drums... and sometimes the brakes pulsate a bit. It is about all I can think of, everything else checks OK.
I have been rebuilding drum brakes almost since I started driving... (disc brakes were kinda new, then...)
Thanks folks!
