I need some advice. My drivers side brake caliper piston will not
release. The brakes stop the van, but afterward the caliper piston
remains tight. After driving down the road the wheel is hot.
I have removed the wheel, taken out the lower retaining bolt, and with
great difficulty pried up the housing. I removed the pads which look to
be about 1/2 worn. I then used a "C" clamp to push the piston back in a
ways, and then I reassembled it all. At that point the unit slides back
and forth on the guide pins as it should, so it is not binding there.
But after I applied the brakes I could, with a pipe
wrench, just barely turn the rotor.
Is this a caliper problem? Can they be rebuilt? I see is
Bentley that you can blow out the piston, but then what? Do you hone the
unit?
Appreciate any advice you may have.
