⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is securely lifted and supported before working underneath.
•Always wear safety glasses and gloves when handling brake components.

Symptoms

•Grinding noise when braking
•Reduced braking performance
•Vibration felt through the brake pedal
•Warning light on the dashboard (if brake wear sensors are present)
•Unusual wear on brake pads or rotors upon inspection

Diagnostic Steps

1
Inspect the rear brake components visually for any signs of wear or damage.

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Remove Wheel

Use a jack to lift the rear of the vehicle and secure it with jack stands.
Remove the wheel lug nuts using a socket set and take off the wheel to expose the brake assembly.

3. Inspect and Replace Brake Pads

Remove the caliper:
- Unbolt the caliper using a socket set, then slide it off the rotor.
- Support the caliper with a bungee cord or rope to avoid straining the brake line.
Remove old brake pads:
- Slide out the old brake pads from the caliper bracket. Check for uneven wear.
Install new brake pads:
- Apply brake grease to the back of the new pads to reduce noise.
- Insert the new pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Remove rotor:
- If the rotor is worn or damaged, remove it by unbolting any retaining screws and sliding it off the hub.
Install new rotor:
- Place the new rotor onto the hub. Secure with screws if applicable.

5. Reassemble Brake Components

Reattach the caliper:
- Position the caliper over the new pads and rotor, then rebolt using the socket set. Torque to manufacturer specifications (usually around 20-30 ft-lbs).
Reinstall wheel:
- Place the wheel back on, hand-tighten the lug nuts, then lower the vehicle and fully torque the lug nuts in a star pattern to manufacturer specifications (usually around 80-100 ft-lbs).

6. Final Checks

Reconnect the negative battery terminal.
Pump the brake pedal a few times to ensure proper brake pad seating and fluid pressure.
