Brakes are the most important safety system on your vehicle, and most brake failures give warning signs first. A periodic brake inspection - or a quick check when something feels off - catches problems early. Here is a practical checklist. If anything looks wrong, have it addressed before driving.
Pads and shoes
- Look at pad thickness through the wheel - if the friction material is thinner than about 1/8 inch (3 mm), plan replacement. See when to replace pads.
- Listen for a wear-indicator squeal or grinding - see brake squeaking.
- Check that both sides of an axle are wearing evenly; uneven wear can mean a sticking caliper.
Rotors
- Look for deep scoring, a heavy rust lip, cracks, or blue heat spots.
- Note any pulsing pedal or steering shudder, which points to uneven rotors - see warped rotors.
Fluid, hoses, and lines
- Check the reservoir level and color - dark fluid or a low level needs attention. See fluid flush guide.
- Inspect flexible hoses for cracks or bulges and metal lines for corrosion or wet spots - see lines vs hoses.
Pedal feel and parking brake
- The pedal should be firm and stop at a consistent height - a soft or sinking pedal is a red flag (see spongy pedal).
- Confirm the parking brake holds the car on an incline and releases cleanly.
When in doubt
Any leak, grinding, or soft pedal means the vehicle should be inspected before further driving. Catching a worn pad early also protects the rotor and saves money. Keep the wear items fresh - the right pads and hardware - and if you are ever unsure, have a professional inspect the brakes.
