Lincoln Mark VII Caliper Pins Sticking
After a few miles of driving, I noticed my car slowing down IMMEDIATELY after releasing the accelerator. My 1988 developed sticking calipers before 15,000 miles. When I parked in the underground lot, my front rotors were reading 170° (F) through the turbines. I figure the calipers were sticking and that the pins needed to be lubed. The next day, I removed one wheel at a time.
I removed the caliper pin retaining clip from the forward edge of the caliper (most cars do not still have these). Using a 3/4 socket, I removed the pins from the caliper.
I lubed the pins by sticking them into the lithium grease up to their threads. I didn't lube the threads because I noticed blue Loc-Tite on them from the factory.
I reinstalled the pin but didn't thread it yet. I put a liberal amount of grease on the pin from the thread to the bottom of the head of the pin. I also noticed the shiny parts of the pin where it had been binding up.
I tightened the pins to the foot pounds specified in my shop manual and repeated the entire procedure for each wheel.
