⚠️ Safety Warnings

Important safety information - read before proceeding

•Always work on a cooled vehicle to avoid burns.
•Ensure the vehicle is securely lifted and supported before working underneath it.

Symptoms

•Grinding noise when applying brakes
•Vibration or pulsation in the brake pedal
•Decreased braking efficiency
•Warning light on the dashboard (if equipped)
•Squealing or squeaking sounds prior to grinding

Diagnostic Steps

1
Inspect brake pads for wear; look for less than 1/8 inch of pad material.
2
Check brake rotors for scoring or damage; use a micrometer to measure thickness.
3
Examine calipers for proper function and any signs of leakage.
4
Inspect brake lines for any cracks or leaks.
5
Assess brake fluid level and quality; check for contamination.

Solution

Solution

1. Preparation

Gather tools and parts as listed below.
Ensure the vehicle is parked on a flat surface and secure with wheel chocks.
Disconnect the battery if working on electrical components.

2. Remove Wheel

Loosen lug nuts with a lug wrench.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set.
Carefully slide the caliper off the rotor, supporting it to avoid strain on the brake line.
Remove the old brake pads from the caliper bracket.
Install new brake pads, ensuring they are properly aligned and seated.

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are damaged or too thin, remove them by unscrewing the retaining screws (if applicable) and sliding them off the hub.
Install new rotors, ensuring they are clean and free of grease.
Torque the rotor retaining screws to the manufacturer’s specifications.

5. Reassemble Brake Components

Reinstall the caliper over the new brake pads and ensure it is aligned.
Tighten the caliper bolts to the specified torque.
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Lower the vehicle from the jack stands and remove the jack.
Torque the lug nuts in a star pattern to the manufacturer’s specifications.
