Rear Brake I think :(
 

This is on my Celica but maybe help give some information as could happen to anyone.

This morning, I went out and the ABS light came on, so I switched off the engine and re-started and the light went out so I carried on then it sounded like I had a flat tyre, keep clonking and the faster I go the more it does it.

I checked Tyres, all fine so checked to make sure the wheels were all tight due to being in for the MOT on monday but they are all good. The one brake pad at the back is a different colour, it's like a rainbow colour but scrapes off and just wondered if this would sort itself out or any suggestions as need the car for tomorrow morning for xmas shopping :(

Thanks

sounds like the caliper could have siezed causing the pads to overheat

if this is the case NO it wont sort its self out> Im not to up on the celica. does it have rear sliding calipers? It could be the sliders have siezed hence only one pad overheating

Yeah bud has Silding Calipers, this would cause a knocking noise?
