Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, brake cleaner, bungee cord or rope, torque wrench.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel using a lug wrench.

2. Remove Brake Components

Remove the Caliper:
- Locate the caliper mounting bolts and remove them using a socket.
- Carefully slide the caliper off the rotor. Use a bungee cord to hang the caliper without straining the brake line.
Remove Brake Pads:
- Slide out the brake pads from the caliper bracket.
- Inspect the backing plate for wear and damage.
Remove Rotor (if necessary):
- If the rotor needs replacement, remove the rotor retaining screws (if equipped).
- Slide the rotor off the hub. If it's stuck, gently tap with a rubber mallet.

3. Inspect and Replace Components

Inspect Brake Pads:
- If worn down to the wear indicator, replace with new brake pads.
- Clean the pad backing plates with brake cleaner.
Inspect and Replace Rotors:
- Check for scoring or excessive wear. If damaged, replace with new rotors.
- Clean the new rotor with brake cleaner before installation.
Check Caliper Mechanism:
- Ensure the caliper slides freely. Lubricate the caliper slide pins if needed.
- Replace caliper if damaged or leaking.

4. Reassemble and Test

Install New Components:
- Place the rotor back on the hub (if replaced).
- Insert new brake pads into the bracket.
- Reinstall the caliper over the new pads and tighten bolts to the manufacturer’s torque specifications (typically around 25-30 Nm).
Reinstall the Wheel:
- Place the wheel back on, hand-tighten the lug nuts, and lower the vehicle.
- Once on the ground, torque the lug nuts to the manufacturer’s specifications (usually around 120 Nm).
