Solution

1. Preparation

Tools Required: Socket set, torque wrench, brake cleaner, jack and jack stands.
Raise the vehicle using a jack and secure it with jack stands.
Ensure safety by wearing gloves and eye protection.

2. Remove Wheel

Remove the lug nuts using a socket wrench.
Take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using the appropriate socket.
2. Carefully lift the caliper off the rotor and support it with a bungee cord or rope (do not let it hang by the brake line).
3. Remove the old brake pads from the caliper bracket.
4. Inspect the brake pads for wear; replace if they are below the manufacturer’s specified thickness.
5. Install new brake pads in the caliper bracket, ensuring they are properly aligned.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Check the rotors for scoring or warping by feeling for uneven surfaces.
2. If replacement is needed, remove the rotor by unbolting it from the hub.
3. Install the new rotor, ensuring it is properly seated.
4. Torque rotor bolts to manufacturer specifications.

5. Reassemble Braking System

Sub-steps:
1. Reposition the caliper over the new brake pads and rotor.
2. Bolt the caliper back in place, ensuring proper torque settings are followed.
3. Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Test Brakes

Lower the vehicle from the jack stands.
Tighten the lug nuts to the specified torque.
Pump the brake pedal several times to seat the brake pads before driving.
