What to pay attention to
Squealing, grinding, a pedal that feels different, vibration under braking or the car pulling to one side are the most common signs worth noting.
Why an inspection may still be needed
Brake noise and wear indicators can point to several different components, so the pads, discs and hydraulic system are usually checked together rather than in isolation.
A sensible next step
Note when the noise or feeling occurs, avoid heavy braking until checked, and book an inspection promptly if a warning light is also showing.
