Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical issues while working on the brakes.

2. Remove Wheel

Tools Required: Socket set, jack, jack stands
Sub-steps:
1. Use a jack to raise the vehicle and place jack stands for support.
2. Remove the lug nuts using a socket wrench and take off the wheel.

3. Inspect and Replace Brake Pads

Tools Required: Brake cleaner, socket set, torque wrench
Sub-steps:
1. Inspect the brake pads for wear; replace if thickness is less than 3mm.
2. Remove the caliper bolts using a socket set.
3. Slide the caliper off the rotor and support it with a bungee cord (do not let it dangle).
4. Remove the old brake pads from the caliper bracket.
5. Clean the caliper bracket and apply brake lubricant to the contact points.
6. Install new brake pads in the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Tools Required: Brake rotor puller (if needed), torque wrench
Sub-steps:
1. Check the rotor for grooves or uneven wear; replace if damaged.
2. Remove the rotor by unscrewing the retaining screws and pulling it off.
3. Clean the hub surface with brake cleaner before installing the new rotor.
4. Install the new rotor and secure it with retaining screws.

5. Reassemble Brake Components

Tools Required: Torque wrench
Sub-steps:
1. Reinstall the caliper over the new brake pads.
2. Tighten the caliper bolts to the manufacturer's specified torque settings (usually between 20-30 ft-lbs).
3. Replace the wheel and hand-tighten the lug nuts.
4. Lower the vehicle and torque the lug nuts to the manufacturer's specifications (usually around 80-100 ft-lbs).

6. Final Checks

Reconnect the battery and check the brake fluid level, topping off if necessary.
Pump the brake pedal to ensure proper brake pad seating.
