Solution

1. Preparation

Tools Required: Wheel chocks, jack, jack stands, lug wrench, brake cleaner, torque wrench, safety goggles, gloves.
Safely park the vehicle on a flat surface and engage the parking brake.
Place wheel chocks behind the rear wheels.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts on the affected wheel.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Brake Pads and Rotors:
- Remove the brake caliper by unbolting it (note any shims or clips).
- Inspect the brake pads for wear; replace if less than 3mm thick.
- Check brake rotors for scoring or warping; replace if necessary.
Brake Fluid:
- Check the brake fluid level and top it off with the manufacturer-recommended fluid type if low.
- Inspect fluid for contamination (dark color or debris); if contaminated, flush the system.

4. Replace Components (if necessary)

If brake pads or rotors are worn, replace them:
- Install new brake pads and ensure they are seated properly.
- Reinstall the brake caliper and torque bolts to manufacturer specifications (usually around 25-35 Nm).
- If rotors are being replaced, ensure they are properly installed and torqued.

5. Reassemble

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and torque the lug nuts to the manufacturer's specifications (typically 100-120 Nm).

6. Test Brake System

Pump the brake pedal several times to ensure proper brake engagement.
Check for any leaks or unusual noises upon first application of brakes.
