Hi Chaps
Thought my brakes were a bit on the not so hot side so just taken them apart to find both inside rear slave cyliders are seized.
Do you know where I can get:-
1) rear caliper repair kit
2) a set of shoe retaining pins (I had to drill and punch mine out)
Or should I go straight to Mercedes?
My procedure to get the siezed piston out was as follows:-
Clamp brake line disconnected caliper, 18mm spanner, remove ratining pins and pull pads out.
I cleaned around the seizure as best i could (rubber seal was shot away!)
After cleaning I sprayed with WD40.
I then put a piece of 10mm steal plate through the caliper and put one end in the vice and the other g clamped to the caliper. Tighten g clamp till it grips tight, then I did the vice up to push the slave cylinder back into the caliper. A spark came out of the hose hole as it let go and moved back into the caliper body. That was the hard bit!
Now re-attach brake hose (I layed it on a couple of breeze blocks) and pump the brake until the slave cylinder pops out.
Now all you need is a repair kit if the actual caliper is not damaged!
