Solution

1. Preparation

Gather tools and parts required for the repair.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the braking components.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket set.
2. Carefully lift the caliper away from the rotor and support it (do not hang it by the brake line).
3. Remove the old brake pads from the caliper bracket.
4. Inspect the caliper slides for lubrication and free movement; clean if necessary.
5. Install new brake pads into the caliper bracket, ensuring they are seated correctly.

Tools Required:

Socket set
Brake cleaner
Torque wrench

3. Inspect and Resurface/Replace Brake Rotors

Sub-steps:
1. Check the rotor surface for grooves or damage.
2. If necessary, remove the rotor by taking off the retaining screws and sliding it off the hub.
3. If the rotor is within specifications, resurface it; if not, replace it with a new rotor.
4. Clean the new or resurfaced rotor with brake cleaner before installation.
5. Reinstall the rotor onto the hub, ensuring it is aligned properly.

4. Reassemble Braking Components

Sub-steps:
1. Reattach the caliper over the new brake pads.
2. Tighten caliper bolts to the manufacturer's specified torque value (usually around 25-35 Nm).
3. Reinstall the wheel and hand-tighten the lug nuts.
4. Lower the vehicle and torque the lug nuts to the manufacturer's specification (usually around 100-120 Nm).
