Hi to all,

Been away for a few weeks and got back to find that the rear brake has seized solid. Removed caliper (eventually), freed everything + greased the bits that needed greasing, finally managed to get pistons back far enough to get caliper back on, squeeze brake pedal, thing seizes once more and this time so that I can't get the caliper back off. Having already spent several hours on this and not getting anywhere please offer some advice on what to do to a) get the caliper back off and b) any ideas on how to fix the problem.

If anyone is in or can get to ealing this afternoon, tea/coffee and biscuits are on offer to anyone who would like to help. Please PM me with you're phone number if you can and I'll give you directions. I need to try and get this fixed today if possible.

Thanks

Mark

Make sure that it is not the brake pedal itself that is seizing. Make sure that the pivots etc are all greased and free.

might be worth taking it away from the system (ie . . . draining the fluid)

that way you can put it in a clamp to release it,

once its released, might be worth overhauling it,
taking everything apart and replacing the seals.

good luck . . . brakes drive me up the wall.

He's right mate, it sounds like it needs an overhall. You could get away with just forcing the pistons back, pumping the brake and then repeating the process untill the pistons move freely but it really does make sense to do the job properly. It will only seize again in time.

New seals will be required, new brake fluid and a bit of mechanical knowledge.

If you dont get any offers from nearby then can i suggest a local garage?

You cant mess about where brakes are concerned mate.

Sorry theres no quick fix.

Well,

After I finally managed to get the caliper off the disc (not the easiest of jobs) and then cleaned it up again (pumped the pistons out further, cleaned and put some rubber lube on for good measure), puts more grease on the pins and the slidy bit of the pad, everything seems to be fine at the moment. Will have to get it sorted in the near future but need to purchase more tools first (like something to bleed brakes with for starters). Certainly the dust seals are shot.

Fingers now numb from pushing pistons back in though...

Thanks for the advice,

MT
