Hi,
Came to service the brakes this last weekend to find front fine, but back was siezed up.
It looks like this winters salt and brake dust has blocked the bottom of the caliper around the retaining spring and the pads have sat ina bath of water. The salt has then pushed the dust seal out as I can see bits of rubber around each piston.
The good news is they push out under hydraulic presure the bad news is at the moment they don't go back under finger pressure.
I am going to do the full works and remove pistons and clean out all the crud and replace with new seals.
Do I crack in half the caliper is this looks to be the quickest way to clean everythink up, better access inside.
Does our rear caliper have the little rubber O-ring that joins brake fluid gallery between the two pieces of the caliper. Or do we have a gasket!
Cheers,
