I'm trying to change the rear disc brake pads on my 95 Civic EX. Passanger
side is now complete. The upper pin on the passanger caliper mounting
bracket was sticking causing the inner pad to wear down. I was able to
free the upper pin and replace it...... On the driver's side, I have
removed the caliper. But, now I can't remove its upper caliper pin in the
caliper mounting bracket housing which is attached to the vehicle. The pin
will not move. I removed the rubber protective sleeve, sprayed PB Blaster
into the pin area multiple times and I tried warming the housing with a
propane torch. I have tried everything but a pipe wrench to break it free.
It will not move at all. Thanks in advance for any ideas or suggestions.
