High-pitched squeal
Many brake pads have a small metal wear indicator that squeals when the pads are getting thin. It is a reminder to book a brake check soon. Light squeal after rain or first thing in the morning can also be surface rust on the rotors, which clears after a few stops.
Grinding
Grinding usually means the pad material is worn through and metal is contacting the rotor. Braking performance drops and the rotor is being damaged with every stop. Get it inspected before driving further.
Pulsing, pulling or a soft pedal
A pulsing pedal or a shaking steering wheel when braking often points to uneven rotors. Pulling to one side can be a sticking caliper or a hose fault. A soft or sinking pedal can mean air or fluid loss in the system, which is a stop-driving symptom.
What to tell the mechanic
The type of noise, which corner it seems to come from, whether it happens on light or firm braking, how the pedal feels and any warning lights.
Safe to drive?
Light squeal and normal pedal: book in soon. Grinding, a soft or sinking pedal, strong pull or a brake warning light: do not drive it. Ask for mobile work or arrange a tow.
General guidance only, not a diagnosis. If in doubt, do not drive it and have it inspected. In an emergency, call 111.

Questions
Do squeaky brakes fail a WOF?
Noise alone may not, but the worn pads or rotors behind it can. Brakes are tested for performance and condition.
Do I always need new rotors?
No. Rotors are measured against a minimum thickness. Ask for the measurement on the quote.
