Hi, I replaced my rear brake calipers last year when my near side starting sticking. I now have a off side starting to stick. Is this normal after just 12 months? Anything I can do to prevent this?

Did you use copper grease when installing it. I know it's been used for years but you shouldn't use it on the caliper slides. Search for brake caliper grease and you'll find a set of three greases for different parts of the installation.

Hmm I actually can’t remember if I used copper or a high temp grease. I think it may have been copper. Is this likely to do it?

If you do use copper grease it really should only go on the back of the pads to help stop squealing. The slides usually have a rubber type grease. Copper grease is to sticky.

Rightio I’ll give them a clean off and start again this weekend. I think it may have actually been the parking brake. I’ve applied it and reapplied a few times and it seems to have sorted it. Just seems odd because the heat seemed to be coming from the outer of the disk not the hub. When I took the wheel off I could hear the shoes rubbing. It all turns freely now so fingers crossed!

Ok, did some investigation. Jacked it up and it sounded like the handbrake was dragging on the discs. I used the handbrake and centred the pads. It seemed to be fine. A week later it’s the same issue again.

Tomorrow I’m going to strip it all down remove the discs and give it all a clean re lube etc unless anyone has anything else I should be looking at?

Make sure you take off and clean/wire brush/file back the rust off the caliper carriers where the pads sit in the anti rattle springs. This is important as the carriers can corrode and grip the pads, and aren’t normally changed along with the calipers.

Unless the pads slip into the stainless springs and move about easily then they will bind in the carrier and you will get overheating.

I use ceratec lube for the ears and back of the pads rather than copper grease. There is nothing that can't be fixed with a hammer😜😜
