Brake Caliper Pins

July 15, 2015, 11:28:50 am

Well, it has been 3 years and I am having my brake caliper pins removed cleaned and inspected and replaced. So far two have been replace and one was seized on the tag pretty good that it took a long time to get it off.  I will decrease the interval to two years from now on to prevent that in the future.  I think this trip other then the slide is all chassis work and it is hot here in Texas in July but MOT has been doing a good job.

This is an important PSA.  We had to make an emergency stop at a CAT dealer to deal with ours when I detected excess heat that I determined to be a hanging caliper.

I don't lube pins. The hanging often is because the chrome plating on the pins is not very good and it bubbles up and hangs.

No lube on my pins. Had 3 replaced and springs added last visit to MOT. The PO of my coach had the springs, but had been talked out of installing them by Wayne at FT.

We have been spraying removed clean dry brake slide pins with CorrosionX, let it sit a moment and then wipe off.  We are aware of the warning to not lub pins, probably so the lub does not attract dirt.  We think that we have not replaced pins because of pits since using CorrosionX.  We have slide pins cleaned and brakes adjusted about every 2 years.

When under coach and looking at other things to check on I have given the pins a quick shot of dry silicone spray. I can get to them when in pit so no worries about hitting the wrong places. Never had any hanging up of pins that I know of!

Not being brave, Annually I remove all wheels, looking at oil seals, brake rotor, slide pins, pads, calipers, slack adjusters, oil level and the general wiring and component condition of the anti locking system.
Then reassemble.  For some reason I have not had an issue with wheels, brakes, leaks or wheel electric sensors and with 116,000 miles, all still looks & acts like new.  Just dumb luck.

Well, I was doing it on a three year interval and now I will move that to two years. I have had 5 pins that needed to be replaced and three of them were frozen in. There were two on the tag and one on the drive.  The fronts were pretty good and only one needed to be replaced.  It was corrosion and we did not lube them.

The pitting didn't look much like corrosion, just failed plating. I was in a bind and couldn't get new pins on one wheel, so I just ground around the pits to make it smooth. There is a decent amount of clearance between the bushings and the pins.

It looked like, on mine that the plating had pealed off and corrosion had started. I wonder about using a spray graphite ?
