The braking system is the most important safety component of your vehicle. Knowing how to recognise signs of wear can help prevent accidents and costly repairs.

Visual signs of wear

Brake pads are visible through the wheel spokes. A new brake pad is typically 10 to 12 mm thick.

Warning thresholds

  • • 3 mm: replacement recommended
  • • 2 mm: urgent replacement
  • • 1 mm: immediate danger

Audible warning signs

Noises to pay attention to

  • • Light squeaking: pads starting to wear
  • • High-pitched squeal: wear indicator activated
  • • Metallic grinding: pads completely worn down

Signs while braking

While driving, be attentive to the following symptoms:

  • • Spongy pedal: air in the hydraulic system
  • • Vibrations when braking: warped brake discs
  • • Vehicle pulling to one side: unbalanced braking
  • • Increased stopping distance: reduced braking efficiency
