Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent electrical issues during repair.

2. Remove Wheel

Tools: Jack, jack stands, lug wrench.
Lift the vehicle using the jack and support it with jack stands.
Remove the wheel using the lug wrench.

3. Inspect Brake Components

Brake Pads:
- Check thickness; replace if below 3mm.
- Tools: Torque wrench for reinstallation.
Brake Rotors:
- Inspect for scoring or warping; replace if necessary.
- Tools: Brake rotor gauge for measuring thickness.
Calipers:
- Ensure calipers move freely; clean and lubricate sliding pins if necessary.

4. Replacement of Brake Pads and Rotors

Tools: Socket set, brake cleaner, brake grease.
Remove old brake pads by unbolting the caliper bracket.
Clean the caliper and rotor surface with brake cleaner.
Install new brake pads, applying brake grease to the backing.
If replacing rotors, remove the old rotor and install the new one, securing it with the appropriate torque specifications.

5. Reassemble

Reinstall the brake caliper and wheel.
Ensure all bolts are tightened to manufacturer specifications.
Reconnect the battery.
