Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery for safety.

2. Remove Wheel

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

3. Inspect Brake Components

Brake Pads: Check the thickness; if less than 3 mm, replace.
Brake Rotors: Measure thickness; replace if below minimum specifications or if warped.
Calipers: Check for sticking or leaks; ensure they move freely.

4. Replace Brake Pads (if necessary)

Carefully remove the old brake pads from the caliper bracket.
Install new brake pads, ensuring they are correctly positioned and secured.
Apply brake grease to the backing of the pads to reduce noise.

5. Reassemble Braking System

Reinstall the brake caliper and ensure it is properly secured.
Replace the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to manufacturer specifications (typically 80-100 ft-lbs).

6. Test Braking System

Reconnect the battery and start the vehicle.
Gently press the brake pedal to ensure proper engagement and check for noise.
