2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on electronic brake systems.
•Allow brakes to cool before servicing to prevent burns.

Symptoms

•Excessive brake dust on one wheel compared to others
•Vibration or pulsation during braking
•Noise such as squeaking or grinding from the brakes
•Reduced braking efficiency
•Warning light for brake wear illuminated on the dashboard

Diagnostic Steps

1
Inspect brake pad thickness on all wheels to compare wear levels.
2
Check for proper installation of the brake pads and calipers.
3
Examine brake caliper operation to ensure they are not sticking or seizing.
4
Inspect brake rotors for warping or uneven surfaces.
5
Check brake fluid levels and condition for contamination.
6
Inspect suspension and steering components for wear that may affect wheel alignment.

Solution

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety gloves and goggles for protection.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which brakes are being serviced.
Secure the vehicle with jack stands to prevent it from falling.

3. Remove the Wheel

Use a lug wrench to loosen and remove the wheel nuts.
Take off the wheel and set it aside.

4. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Measure the thickness of the brake pads and compare them.
- Check for signs of uneven wear.
Remove Old Brake Pads:
- Use a socket wrench to remove the caliper bolts.
- Carefully slide the caliper off the rotor and support it (do not let it hang by the brake line).
- Remove the brake pads from the caliper bracket.
Install New Brake Pads:
- Clean the caliper bracket and apply brake grease to the contact points of the new pads.
- Install the new brake pads into the caliper bracket.

5. Reassemble Components

Reattach Caliper:
- Slide the caliper back over the new brake pads and rotor.
- Secure the caliper by tightening the caliper bolts to the manufacturer's specified torque (typically around 30-40 Nm).
Reinstall Wheel:
- Place the wheel back onto the hub and hand-tighten the lug nuts.
- Lower the vehicle and then tighten the lug nuts to the specified torque (usually 100-120 Nm).

6. Brake System Check

Pump the brake pedal several times to ensure proper pad seating and brake pressure.
Inspect for any signs of leaks around the caliper and brake lines.
