Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Wear safety gloves and goggles.

2. Remove Wheel

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

3. Inspect Brake Components

Sub-steps:
1. Visually inspect brake pads for thickness; replace if less than 3mm.
2. Check the brake rotors for warping using a dial indicator; replace if warping exceeds manufacturer specifications.
3. Examine calipers for sticking or uneven movement; clean or replace as necessary.
Tools Required: Dial indicator, caliper tool, brake cleaner.

4. Replace or Resurface Rotors

Sub-steps:
1. If rotors are warped, remove them by unscrewing the caliper bracket bolts.
2. Replace with new rotors or have them resurfaced if within specification.
3. Clean the new or resurfaced rotors with brake cleaner before installation.
Tools Required: Socket set, torque wrench.
Torque Specification: Tighten caliper bracket bolts to manufacturer torque specifications (typically around 70-90 ft-lbs).

5. Install New Brake Pads

Sub-steps:
1. Place new brake pads into the caliper bracket.
2. Compress the caliper piston using a caliper tool if necessary.
3. Reattach the caliper over the new pads and secure with bolts.
Tools Required: Caliper compression tool, socket set.

6. Reassemble

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle and then torque the lug nuts to manufacturer specifications (typically 76-80 ft-lbs).
Tools Required: Torque wrench.
