Hey,

my 2013 R59 JCW was always noisy/squeaky in terms of brakes.
But today I drove and I noticed a grinding noise coming from the right side of the car. I tried to brake it off and was hoping that heat and break force will fix it.
Really noisy grinding noise, no matter how fast I was going, increased when brakes applied.
Well, took down the right rear wheel off and saw that the outside brake pad was worn down to not even 1 millimeter. The left rear brake pads looked okay, maybe at 50% of brake pad left.
Both sides at the front were again somewhere around 50% left, maybe a little less left at the right front side.

Any idea why my right side, especially at the rear wore down to almost nothing?
i guess that’s why it started grinding, squealing and squeaking right?

Notice this: my CBS brake pad sensors showed that fronts need replacing in 3500 km and rears that were worn out(right side only where the sensor is) showed 1500 km. I guess the sensor was off positioned.

what can be the cause of this, anyway time to replace rear front pads.

thanks!

 

I had the same problem with my '12 Cooper. Rear right outside pad gone with the others being almost new. Ended up being just a stuck floating caliper. Took the pads out, cleaned the caliper really well, greased up the floating slides for the caliper, put new pads on it and have not had a problem since. The caliper is sticking on yours, so if the cleaning/greasing does not work, get another caliper (either way you will still need new pads) and be sure to use some brake grease on the new slides.

 

Caliper stuck or sticky parking brake cables..

 

thanks for inputs, it was a stuck piston/caliper

 

welcome.
