Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear protective gloves and safety glasses.

2. Remove Wheel

Sub-steps:
1. Loosen lug nuts using a socket wrench.
2. Lift the vehicle using a jack and secure it with jack stands.
3. Remove the lug nuts and take off the wheel.
Tools Required: Jack, jack stands, socket set

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the brake caliper by unbolting it from its bracket.
2. Carefully slide the caliper off the rotor and support it (do not let it hang by the brake line).
3. Remove the old brake pads from the caliper bracket.
4. Compare new brake pads with the old ones for wear.
5. If necessary, replace the brake pads with new ones ensuring they are properly aligned.
Tools Required: Torque wrench, socket set

4. Inspect Brake Rotors

Sub-steps:
1. Check the rotors for scoring, warping, or excessive wear.
2. If rotors are damaged, replace them.
3. If rotors are in good condition, clean them with brake cleaner to remove dust and debris.
Tools Required: Brake cleaner, rotor tool if replacing

5. Reassemble and Test

Sub-steps:
1. Reinstall the brake caliper over the new pads and torque the bolts to manufacturer specifications.
2. Reattach the wheel and torque lug nuts in a crisscross pattern.
3. Lower the vehicle and remove jack stands.
4. Test the brakes by pressing the pedal to ensure proper operation.
