rear disc overheating

Hi

My rear disc appears to be overheating, I recently replaced the rear brake pads but now I fear something has gone wrong!!

Any suggestions before I take it to the mechanic?

Thanks

Pistons seizing, not uncommon in the slightest. You need to or have someone, overhaul the calliper.

Agree with B.A. If you're not very hands on may be cheaper to source a recon / low mileage caliper from e bay or breakers.

I've worn out two wavy discs cause of my crappy rear brake.

The pistons in the caliper are quite easy to get to, once you've got the pads and pins out, pump the brake a little to check both pistons come out a few mm from where they are (You may need to restrain or hold one if one moves and the other doesn't. Then get some hot water and a toothbrush and scrub the pistons clean all round, when dry use some universal rubber grease on a toothbrush to lightly coat the pistons and gently slide them back in by hand. put pads back in and problem should be sorted.

Well worth doing that cleaning regime, but if there's crap behind the seals then it's more involved than that. Wonder why they the caliper where all the crud goes straight in there?

Thanks for all your replies, most helpful!

Will let you know how it goes

Thanks

I have replaced the rear caliper on mine twice, first time at about 50k, second time at 104k, I replaces my front calipers at 92k.

I found brand new calipers to be the best way to go, there not very expensive here in the US, about the same as a couple hours of labor, cheaper than the cost of a rebuild kit and labor time to do the rebuild
