Squealing
Many brake pads have a small metal wear indicator that squeals against the rotor when the pad gets thin. A squeal that's there all the time when you brake usually means it's time for pads. A squeal only on the first few stops on a damp morning is often just moisture and goes away.
Grinding
Grinding usually means the pad material is gone and metal is hitting metal. Get it fixed right away — it's chewing up your rotors and your stopping power is compromised.
Other warning signs
- Vibration or pulsing in the brake pedal
- Longer stopping distances
- A soft or sinking pedal
- The car pulling to one side when braking
- A brake warning light on the dash
How thin is too thin?
As a general rule, brake pads should be replaced at about 3–4 mm of pad material left. Some manufacturers call for replacement at 4 mm.
When not to drive
A soft or sinking pedal, a brake fluid leak, or a red brake warning light can mean a hydraulic problem — like a leaking brake line. Don't drive on it. We can come to you and fix it where it sits.
