⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on electrical systems.
•Allow the brakes to cool down before inspecting or working on them.

Symptoms

•Squeaking or squealing noise when braking
•Grinding noise indicating possible metal-to-metal contact
•Increased brake pedal travel or sponginess
•Vibration or pulsation felt through the brake pedal
•Reduced stopping power or brake fade

Diagnostic Steps

1
Inspect brake pads for wear and thickness using a visual inspection.
2
Check brake rotors for warping or uneven wear by measuring rotor thickness with a micrometer.
3
Examine brake calipers for proper operation and any signs of leakage or damage.
4
Look for debris or foreign objects lodged in the brake assembly.
5
Verify brake fluid level and condition in the master cylinder reservoir.
6
Use an OBD-II scanner to check for any related error codes.

Solution

Solution

1. Preparation

Gather tools and materials required for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety gloves and goggles.

2. Lift Vehicle

Use a jack to lift the front or rear of the vehicle, depending on the brakes being serviced.
Securely place jack stands under the vehicle for safety.

3. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts.
Take off the wheel to access the brake components.

4. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the thickness of the pads; if less than 3mm, replace.
Remove Caliper:
- Use a socket set to remove the caliper bolts and slide the caliper off the rotor.
Replace Pads:
- Remove old pads from the caliper bracket.
- Install new brake pads, ensuring they are seated correctly.

5. Inspect and Replace Rotors (if necessary)

Remove Rotor:
- If rotors are worn or damaged, remove them by removing the retaining screws and sliding them off the hub.
Install New Rotor:
- Place the new rotor onto the hub, ensuring it is flush against the surface.

6. Reassemble Brake Components

Reinstall Caliper:
- Slide the caliper back over the new pads and rotor.
- Tighten caliper bolts to manufacturer torque specifications (typically around 20-30 ft-lbs).
Reattach Wheel:
- Place the wheel back onto the hub and hand-tighten the lug nuts.

7. Lower Vehicle

Carefully lower the vehicle off the jack stands using the jack.

8. Final Checks

Tighten lug nuts to manufacturer specifications (typically 75-100 ft-lbs).
Pump the brake pedal a few times to ensure proper brake pressure before driving.
