Brakes are the one system where 'I'll get to it next month' is genuinely dangerous. The reassuring part is that they almost always warn you first — if you know what the warnings sound and feel like.

The sounds

  • A high squeal when braking: pads are worn down to their wear indicators — time to replace
  • A harsh grinding: the pads are gone and metal is contacting the disc — stop driving and get it seen immediately

The feelings

  • Vibration or pulsing through the pedal: often warped discs
  • A soft or spongy pedal: possible air in the lines or a fluid problem
  • A pedal that slowly sinks to the floor: a serious hydraulic issue — do not drive
  • The car pulling to one side under braking: a sticking caliper or uneven wear
