Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative battery terminal to avoid any electrical issues.

2. Remove Wheel

Tools Required: Jack and jack stands, lug wrench.
Loosen lug nuts slightly while the vehicle is still on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

Check the brake pads for thickness; replace if less than 3 mm.
Inspect the rotors for grooves or warping; replace if necessary.
If pads or rotors are worn, follow these sub-steps:
- Brake Pad Replacement:
  1. Remove the caliper bolts using a socket wrench.
  2. Slide caliper off the rotor and support it without straining the brake line.
  3. Remove old brake pads from the caliper bracket.
  4. Install new brake pads in the bracket.
- Rotor Replacement:
  1. Remove the caliper bracket by unscrewing the necessary bolts.
  2. Slide the old rotor off the hub and replace with a new rotor.
  3. Reinstall the caliper bracket.

4. Reassemble and Reinstall

Reattach the caliper over the new pads and rotor, securing it with the caliper bolts.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer's specifications (typically 80-100 ft-lbs).

5. Final Steps

Reconnect the negative battery terminal.
Pump the brake pedal to ensure proper pad seating.
Check brake fluid level and top off if necessary.
