Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Use wheel chocks to secure the vehicle.

2. Remove Wheel

Sub-steps:
1. Loosen the lug nuts slightly while the vehicle is on the ground.
2. Lift the vehicle with a jack and place jack stands under the frame.
3. Remove the lug nuts and take off the wheel.
Tools Required: Jack, jack stands, lug wrench.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket set.
2. Slide the caliper off the rotor and suspend it with a bungee cord to avoid putting stress on the brake line.
3. Remove the old brake pads and inspect for wear; replace if they are below manufacturer specifications (usually less than 3mm).
4. Install new brake pads, ensuring they are seated correctly in the caliper bracket.
Tools Required: Socket set, bungee cord, brake cleaner.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. If the rotors are damaged or worn, remove the rotor by unscrewing the retaining screws (if applicable).
2. Inspect the rotor surface for grooves or warping; replace if necessary.
3. If the rotors are in good condition, clean the surface with brake cleaner to remove any debris.
4. Reinstall the rotor and secure it with retaining screws.
Tools Required: Screwdriver, brake cleaner.

5. Reassemble Brake Components

Sub-steps:
1. Reattach the caliper over the new brake pads and secure it with caliper bolts.
2. Tighten caliper bolts to manufacturer specifications (usually around 20-25 ft-lbs).
3. Reinstall the wheel and hand-tighten the lug nuts.
Tools Required: Torque wrench.

6. Lower Vehicle and Final Check

Sub-steps:
1. Lower the vehicle off jack stands.
2. Tighten lug nuts to manufacturer specifications (usually around 76 ft-lbs).
3. Pump the brake pedal several times to ensure proper pad seating.
Tools Required: Torque wrench.
