Title: MOT euphoria dashed
Post by: fish on April 09, 2007, 22:01:47

Got back from an MOT after the old girl went straight though with only the obligatory rust warnings, only to smell overheated brakes. Turns out rear calliper piston has seized on the 5 mile trip back. Is there any cure other than a calliper replacement? If not where is is the best place to buy one, have had a quick look on the net, prices varing fom 46-102 quid, are the cheaper (PADDOCKS)ones OK?

Try taking the brake pads out and soaking the pistons in WD40 and working them in and out. It worked with my front caliper.

copper grease is a good way to free em up and make sure they dont stick again. I replaced one of my rears with a paddocks one and its been spot on...so go for it.

The combination of a petroleum product and the rubber of the seals in the braking system is not a good idea. It is likely to cause deterioration of the rubber and if it manages to get past the seal it will contaminate the brake fluid.

You might be able to clean the pistons up with a proper brake cleaner, but if the pistons are rusty and pitted then repacement calipers is the best route.

If your pads are worn low, a possible fix would be new pads, could be why they are sticking as they are on full stretch

Also word discs in conjunction with the above
