Solution

1. Preparation

Gather tools and parts needed for the repair.
Safely lift the vehicle using a jack and secure it with jack stands.
Disconnect the battery to avoid any electrical issues.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts on the wheel.
Remove the lug nuts and take off the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper by unscrewing the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor and support it with a bungee cord or rope to avoid straining the brake line.
- Check the brake pads for wear; replace if they are below the minimum thickness (usually 3mm).
Replace Brake Pads:
- If necessary, remove the old brake pads by sliding them out of the caliper bracket.
- Insert new brake pads into the caliper bracket, ensuring they are correctly aligned.

4. Inspect and Replace Brake Rotors (if needed)

Check the rotors for deep grooves or excessive wear. If damaged, remove the rotor by unscrewing the rotor screws (if equipped) and sliding it off the hub.
Install new rotors if necessary, ensuring they are properly seated and secured.

5. Reassemble Brake Components

Reattach the caliper over the new brake pads and rotor.
Tighten the caliper bolts to the manufacturer’s torque specifications (usually 25-35 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Final Steps

Lower the vehicle and remove the jack stands.
Tighten the lug nuts in a crisscross pattern to ensure even pressure.
Reconnect the battery.
