Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is secure on jack stands before working underneath.
•Always allow brakes to cool before inspection or repair to avoid burns.

Symptoms

•Grinding noise when applying brakes
•Reduced braking efficiency
•Vibration in the brake pedal
•Brake warning light illuminated
•Increased stopping distance

Diagnostic Steps

1
Inspect brake pads for wear and tear using a visual check.
2
Check for debris or foreign objects lodged in the brake caliper or rotor.
3
Measure brake pad thickness with a caliper to determine if replacement is needed.
4
Examine brake rotors for scoring or warping.
5
Scan the vehicle for any error codes related to the braking system using an OBD-II scanner.

Solution

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle (depending on which brakes are making noise).
Secure the vehicle with jack stands to ensure stability.

3. Remove the Wheel

Use a socket set to remove the lug nuts from the wheel.
Take off the wheel to access the braking components.

4. Inspect Brake Components

Remove the brake caliper by unscrewing the caliper bolts using a socket.
Carefully slide the caliper off the rotor without disconnecting the brake line.
Inspect the brake pads for wear; replace if below the manufacturer’s specified thickness (usually 3mm).
Examine the brake rotor for any scoring or damage; replace if necessary.

5. Clean and Lubricate

Clean the brake rotor and caliper with brake cleaner to remove dust and debris.
Apply brake grease to the caliper slide pins and the back of the brake pads to minimize noise.

6. Reassemble

Reposition the brake caliper over the rotor and tighten caliper bolts to the manufacturer’s torque specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value.

7. Test the Brakes

Start the vehicle and gently pump the brakes to ensure proper engagement.
Conduct a short test drive to confirm the grinding noise is resolved.
