Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Use wheel chocks for added safety.

2. Remove Wheel

Sub-steps:
1. Loosen lug nuts with a lug wrench.
2. Raise the vehicle with a jack and support it on 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 caliper bolts using a socket set.
2. Carefully slide the caliper off the rotor and suspend it using a bungee cord to avoid stress on the brake line.
3. Remove old brake pads and inspect for wear; replace if they are below the manufacturer's minimum thickness (typically 3mm or less).
4. Install new brake pads and ensure they are properly seated in the caliper bracket.
Tools Required: Socket set, bungee cord.

4. Inspect and Resurface/Replace Rotors

Sub-steps:
1. Check rotors for grooves or warping; if uneven, consider resurfacing or replacing.
2. If replacing, remove the rotor by unscrewing the retaining screws (if equipped) and sliding it off the hub.
3. Install new or resurfaced rotors, ensuring they are clean and free of debris.
Tools Required: Torque wrench, rotor puller (if necessary).

5. Reassemble Braking System

Sub-steps:
1. Reattach the caliper over the new brake pads and tighten caliper bolts to the manufacturer's specifications (typically 25-30 ft-lbs).
2. Reinstall the wheel and hand-tighten lug nuts.
3. Lower the vehicle and torque the lug nuts to the manufacturer's specification (usually 80-100 ft-lbs).
Tools Required: Torque wrench.

6. Final Checks

Pump the brake pedal to seat the pads against the rotors.
Check brake fluid level and add as needed.
