Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Use wheel chocks to prevent rolling.

2. Remove Wheel

Sub-steps:
- Loosen the lug nuts with a lug wrench while the vehicle is on the ground.
- Raise the vehicle using a jack and secure it with jack stands.
- Fully remove the lug nuts and take off the wheel.

3. Inspect Brake Components

Sub-steps:
- Remove the caliper bolts using a socket set and slide the caliper off the rotor.
- Inspect the brake pads for thickness; if less than 3mm, replace them.
- Check the rotors for grooves or warping; if damaged, replace them.

4. Replace Brake Pads and/or Rotors

Sub-steps:
- If replacing pads, remove the old pads and install new ones ensuring they are properly seated.
- If replacing rotors, remove the old rotor and install the new rotor, tightening bolts to manufacturer's torque specifications (typically around 100-120 ft-lbs).

5. Reassemble Brake System

Sub-steps:
- Reinstall the caliper over the new pads and rotor, securing it with the caliper bolts.
- Reattach the wheel and hand-tighten the lug nuts.
- Lower the vehicle and then fully tighten the lug nuts in a star pattern to the recommended torque specification (typically around 76-86 ft-lbs).

6. Final Checks

Sub-steps:
- Pump the brake pedal to seat the pads against the rotor.
- Check brake fluid level and top off if necessary.
- Test the braking system by performing a low-speed brake test.

Tools Required:

Jack and jack stands
Lug wrench
Socket set
Torque wrench
Brake cleaner
C-clamp or brake caliper tool (for compressing caliper piston)

Parts Required:

Brake pads
Brake rotors (if necessary)
Brake fluid (if needed)

Estimated Repair Time: 2-4 hours

Safety Warnings:

Always disconnect the battery before working on electrical systems.
Allow the vehicle to cool down before working on the brakes to avoid burns.
