Rear brake seized

[ProXimaCore]

My rear brake is seized up. Only on the left side, but I'm changing the pads tonight and I was wondering what I have to do to 'un-seize' it. I take it I have to take the caliper to bits. I'm not quite sure what I'm doing though. I've never even changed brake pads before. Can anyone offer any help?

I found Korn's brake cleaning guide very helpful.

I followed it yesterday as my front caliper was binding badly.

Diagnosed as a grubby piston. All cleaned and working, after spurting a few cc's of brake fluid over the garage!

Hi

Seized rear caliper? You bought a Suzuki . Blooming nightmare.

Chances are that the pins that locate the pads into the caliper is seized solidly in place. I would advise you to order new pins before you try changing the pads.

The pistons probably just need cleaning upand pushing back.

All the best

Right I was about to make a start at this and I realised while the back wheel has been off for a while, I have gone and pressed the rear brake lever at some point and the brake pads are hard up against each other. How do I get them apart again?

Get a large flat bladed screwdriver and wedge it between the pads and push the pads away from each other with it, this will push the pistons back into the calipers.
