Brakes squealing or grinding

A high squeal when braking is often the wear indicator doing its job. A low metallic grinding means the pad is gone and metal is eating the disc.

What you can check yourself

  1. Look through the wheel: less than 3 mm of friction material left means new pads.
  2. Run a finger over the cold disc: a pronounced lip means a worn disc.
