Bad brake calliper piston

Just a little info in case anyone else is having the same issue. Have a 2009 Mini Cooper Clubman (diesel engine) with 130,000km (80,000miles). For the last two weeks, pushing and holding the brake pedal results in what I can only describe as a clunking noise. Sounds a little like hot water pipes expanding. The longer/harder you push the brake, the more the clunking.

Turns out the driver's side (left hand drive) brake calliper piston is going bad. Repair will cost me €350 including changing the piston and flushing the brake fluid. Dealership says the calliper is more expensive for the diesel engine as the heavier engine up front requires a bigger calliper piston. For the Cooper S model, the price would have been about €250.

Not changing it means at some point the brake is likely to bind.

Hope that might help someone.

Have you thought about buying a calliper rebuild kit, they are pretty cheap and it is not a difficult job to do. Might save you some pennies and yeah, you don't want to let the brakes bind, the heat will might warp the disc.

Don't have much time to fiddle with the car on my own. Also, I live in the countryside and it's my only car. Can't afford to mess anything up.

Your point is well taken, though.
