Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, gloves, safety glasses.
Ensure the vehicle is parked on a level surface and the ignition is off.
Wear safety gloves and glasses for protection.

2. Lift the Vehicle

Use a lug wrench to loosen the lug nuts on the affected wheel.
Jack up the vehicle and securely place it on jack stands.
Remove the lug nuts and take off the wheel.

3. Remove Brake Components

Brake Pads Replacement:
- Use a socket set to remove the caliper mounting bolts.
- Carefully slide the caliper off the brake rotor and support it without stressing the brake line.
- Remove the old brake pads from the caliper bracket.
Brake Rotor Replacement (if needed):
- Remove the caliper bracket if rotors are being replaced.
- Remove the rotor by unscrewing any retaining screws, if present, and sliding it off the hub.

4. Inspect and Clean

Inspect the brake rotor and pads for wear. If the pads are less than 3mm thick or the rotor is damaged, replacement is necessary.
Clean the caliper, caliper bracket, and rotor mounting surface with brake cleaner to remove dust and debris.

5. Install New Components

New Brake Pads:
- Place new brake pads into the caliper bracket. Ensure they’re seated properly.
New Brake Rotor: (if applicable)
- Slide the new rotor onto the hub, securing it with any retaining screws if applicable.
Reattach the caliper over the new pads and rotor.
Torque the caliper mounting bolts to the manufacturer’s specifications (usually around 25-30 Nm, but check the service manual for precise values).

6. Reassemble Wheel

Place the wheel back onto the hub.
Hand-tighten the lug nuts and lower the vehicle.
Tighten lug nuts to the manufacturer’s specifications (typically 90-110 Nm).

7. Brake Fluid Check

If brake pads were replaced, check the brake fluid level in the reservoir. Top up if necessary with the appropriate brake fluid (DOT 4 recommended).
