Important safety information - read before proceeding

•Always disconnect the battery before working on electrical systems.
•Allow brakes to cool before inspection or repairs.

Symptoms

•High-pitched squealing noise when applying brakes
•Possible vibration in the brake pedal
•Decreased braking efficiency
•Brake warning light may illuminate
•Excessive dust accumulation on wheels

Diagnostic Steps

1
Inspect brake pads for wear and thickness using a caliper gauge.
2
Check brake rotors for any signs of scoring or damage.
3
Examine brake fluid level and condition in the master cylinder.
4
Look for any debris or foreign objects lodged between the brake pad and rotor.
5
Test drive the vehicle to determine if the noise persists under different braking conditions.

Solution

Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, caliper gauge, brake cleaner, torque wrench.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Raise the Vehicle

Loosen the lug nuts on the wheel where the noise is occurring.
Use the jack to lift the vehicle and secure it on jack stands.
Remove the wheel using the lug wrench.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using the appropriate socket.
Carefully lift the caliper off the rotor without disconnecting the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the pads for wear; if less than 3mm thick, replace them.
Apply brake grease to the back of the new pads to reduce noise.
Install the new brake pads into the caliper bracket.

4. Inspect and Resurface Brake Rotors

Check for rotor thickness using the caliper gauge; if below minimum specs, replace the rotor.
If the rotor is within specs, use a brake lathe to resurface the rotor or replace it if excessively worn or damaged.
Clean the rotor surface with brake cleaner to remove dust and grease.

5. Reassemble and Lower the Vehicle

Reattach the caliper over the new brake pads and secure it with the caliper bolts.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and torque the lug nuts to the manufacturer’s specifications (usually around 100 ft-lbs).
