Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure vehicle is parked on a flat surface, and apply the parking brake.
Wear safety goggles and gloves.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle as needed.
Secure the vehicle with jack stands.

3. Remove Wheel

Using a socket set, remove the lug nuts from the wheel.
Take off the wheel to access the brake components.

4. Inspect and Replace Brake Pads

Inspect: Remove the brake caliper by unbolting it (torque specs: 25 Nm).
Check Brake Pads: Look for uneven wear, thickness less than 3mm indicates replacement is needed.
Replace Brake Pads: If worn, remove old pads and install new pads ensuring they fit snugly in the caliper.

5. Inspect Brake Rotors

Check Condition: Examine the rotors for grooves or uneven surfaces.
Replace if Necessary: If damaged, unbolt the rotor (torque specs: 10 Nm) and install a new rotor.

6. Reassemble Components

Reinstall the brake caliper over the new pads and rotor.
Tighten caliper bolts to the specified torque.
Reattach the wheel and hand-tighten lug nuts.

7. Lower Vehicle and Test

Carefully lower the vehicle from the jack stands.
Tighten the lug nuts to the specified torque (typically 100 Nm).
Test the brakes gently to ensure proper functioning and listen for any noises.
