Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Disconnect the battery to prevent any electrical issues during repair.

2. Remove Wheel

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

3. Inspect and Replace Brake Components

Tools Required: Socket set, torque wrench
Sub-steps:
1. Remove the caliper bolts using the socket set.
2. Carefully slide the caliper off the rotor without stretching the brake line.
3. Inspect brake pads for wear; replace if the friction material is below 3mm or shows uneven wear.
4. Check the brake rotor for any grooves or warping; replace if necessary.
5. Clean the caliper and rotor surfaces using brake cleaner.
6. Apply brake grease to the back of the new brake pads and the caliper guide pins.
7. Reinstall the caliper and torque the bolts to manufacturer specifications (usually around 25-35 lb-ft).

4. Reassemble Wheel

Sub-steps:
1. Place the wheel back onto the hub.
2. Hand-tighten the lug nuts before lowering the vehicle.
3. Lower the vehicle and then torque the lug nuts to manufacturer specifications (typically 80-100 lb-ft).

5. Final Checks

Tools Required: Brake fluid level tester (optional)
Sub-steps:
1. Reconnect the battery.
2. Check and top off the brake fluid level if necessary.
3. Test the brakes by pressing the pedal several times to seat the pads.
