Hey gang,

The right rear caliper on my 05 S-type seems to be sticking. At first I thought the parking brake was at fault, but after disconnecting the EPB cable I still have the same issue. I had changed the rear pads & rotors not long ago and noticed that the right pads were far more worn than the left, so this issue seems to have been brewing for a little while.

Has anyone had luck re-building these themselves (any tricks or tips on disassembling, etc.?)? Any good non-dealer sources for new calipers?

I guess I should also check for a collapsed flexible brake hose too as sometimes those will allow fluid out but not back in (keeping pressure on the caliper).

Thanks in advance,

Bob

 

Were the pins that the caliper slides on free and easy to move?

 

Probably they're seized
But may free up

 

Thanks guys.... good point on the pins. I kind of forgot about that aspect of it... I'll check the movement of those tonight. I pulled the caliper off late yesterday but hadn't had a chance to give it a good look yet.

 

Good call on the pins Mikey. One of them is seized up bigger than Dallas... I couldn't even budge it with a drift and hammer with the caliper in a vise. Looks like I'll try one of those re-manufactured calipers from Napa for ~$150.

This is probably one of those things everyone should check when changing pads... make sure the pins are well greased and the boots that cover them are on tight and not torn. I could see how a torn or improperly seated boot would let all sorts of crap into the pins and contribute to such a failure.

Thanks again guys,

Bob

 

Glad you found what was wrong, even though it will cost a bit to fix.

 

My mate (who's arguably a bit over-keen) regreases the pins on each service.
(I know!)

Like him I take the wheels off at each service, check them for damage etc and check all the suspension, brake pipes, wires, etc as best I can.
