Has anyone had an issue with a rear caliper sticking on ,it has happened to me a few times and i only catch it when I smell the brake burn, I have new calipers and rotors in the last 1.5 years and the first time it occured I took them all apart and cleaned everything lubed it well and put back together, It just happened again yesterday , I usually pull over stomp the brake pedal a few time then take off ,any ideas thanks.

 

Mine was sticky and I found out which one by driving and rolling to a stop, the "shooting" the brake discs with an IR thermometer, on the same axl they shoulod be very close in temps. One of mine was 40F hotter. Rebuild kits for calipers are usually not cost effective, by the time they start sticking the bore is worn.

have a 93 300 CE Cabrio..... with 94 head lights.

 

Use brake grease, cover piston shoulders after they've been cleaned. Keeps caliper pistons from binding due to hardened dust and rust. I keep a set of old pads to extend the pistons, remove pads, coat shoulders then reinstall newer pads.

Best of luck.

 

I don't know about that. A rebuild kit for rear calipers is $24 from RovahFarm and that includes the two needed pistons. The inside bore of the caliper should not be worn at all as the piston rides on the seals. There is no metal to metal contact.
Rebuilding calipers is pretty easy. Having compressed air helps a lot as does a vise and/or C-clamps. Lots of vids on the YouTube about it. The hardest part is overcoming the mental hurdle of digging into brake calipers.

*Do NOT split the caliper halves unless you have the channel seals in hand to replace them.
