Solution

1. Preparation

Gather tools and parts required for the brake repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Gather safety equipment such as gloves and safety glasses.

2. Remove Wheel

Sub-steps:
1. Loosen lug nuts slightly while the vehicle is on the ground.
2. Raise the vehicle using a jack and secure it with jack stands.
3. Remove the lug nuts and take off the wheel.
Tools Required: Lug wrench, jack, jack stands.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket wrench.
2. Carefully slide the caliper off the brake rotor. Support it using a bungee cord or similar method to avoid stress on the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Compare old pads with new ones; ensure new pads are the same size.
5. Install new brake pads into the caliper bracket.
Tools Required: Socket wrench, bungee cord.

4. Inspect and Replace Rotors (if necessary)

Sub-steps:
1. Check the rotor surface for scoring or significant wear.
2. If replacement is needed, remove the caliper bracket and then the rotor.
3. Install the new rotor, ensuring it is seated correctly.
4. Reattach the caliper bracket over the rotor.
Tools Required: Socket wrench.

5. Reassemble and Test

Sub-steps:
1. Reinstall the caliper over the new brake pads and torque the caliper bolts to manufacturer specifications.
2. Reinstall the wheel and torque the lug nuts in a crisscross pattern.
3. Lower the vehicle and pump the brake pedal to seat the brake pads.
Tools Required: Torque wrench.
