The brake pads on the rear right caliper are wearing stupidly fast on my '06 Saab TiD. In 10k miles the rear right had gone down from 10mm to 4mm, whilst the left rear have only gone down 1mm.

The front pads have gone down 3mm only in 25k miles.

It basically looks like most braking is on the rear right caliper, which is odd as the imbalance wasn't reported in the MOT test last ear (the next one is due in November).

  • sliding pins clean and greased
  • calipers clean
  • pistons retracting smoothly and gators intact
  • brake fluid (replaced last year) checked for contamination (less than 1%, so nearly new)
  • no warning lights and nothing comes up on the ODB scanner
  • pads worn evenly - see pic, pads are reversed i.e. right pads on the left
  • the car does not steer to the left or right when braking

I talked to a mechanic who thinks it might be ABS unit: is there a way to test it? Other options?

  • Check the flexible to that caliper - it could be holding pressure to the caliper and wearing the pads...

  • Another thing to check would be the rubber hose to the caliper. It's fairly rare but they can degrade and function as a check valve.

  • I don't know what kind of checks as they both look fine - dry, no cracks, unusual bends or other. I moved them around as I removed the calipers and there was nothing unusual

  • @GabeWisneski I think I wrote what you wrote just a few hours earlier...

  • You have a sticking caliper on that side, replace it.
