Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent any electrical issues.

Tools Required:

Jack and jack stands
Lug wrench
Socket set
Torque wrench
Brake cleaner
Brake grease
Caliper tool (if necessary)

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Raise 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 Pads

Inspect Brake Pads:
- Check the thickness of the brake pads; replace if they are below the manufacturer’s specification (usually around 3mm).
Remove Brake Caliper:
- Unfasten the caliper mounting bolts using the socket set.
- Carefully slide the caliper off the rotor; support it using a bungee cord or similar to avoid stressing the brake line.
Remove Old Brake Pads:
- Slide the old brake pads out of their slots.
Install New Brake Pads:
- Apply brake grease to the backing of the new pads (avoid the friction surface).
- Insert the new pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Check Rotor Condition:
- Inspect for grooves or scoring; if damaged, replace.
Remove Rotor:
- Remove any retaining screws and slide the rotor off the hub.
Install New Rotor:
- Position the new rotor and fasten it as required.

5. Reassemble the Braking System

Reattach Caliper:
- Slide the caliper over the new brake pads and rotor.
- Tighten the caliper mounting bolts to the manufacturer’s specified torque.
Reinstall Wheel:
- Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower Vehicle:
- Remove the jack stands and lower the vehicle.
Tighten Lug Nuts:
- Once the vehicle is back on the ground, tighten the lug nuts to the manufacturer’s specified torque in a crisscross pattern.
