Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery to prevent accidental engagement of any electrical components.

2. Remove the Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a socket wrench and take off the wheel.

3. Inspect and Replace Brake Components

Inspect Brake Pads:
- Check for uneven wear. If significant wear is noted, replace the affected brake pads.
Caliper Inspection:
- Remove the caliper bolts with a socket set, then slide the caliper off the rotor. Inspect the caliper for proper movement.
- If the caliper is seized, replace it with a new unit.
Brake Rotor Inspection:
- Check the rotor for warping or scoring. If it’s uneven, either resurface or replace the rotor.

4. Reassemble and Torque

Install New Components:
- If replacing pads or rotors, install new components in reverse order of removal.
Torque Specifications:
- Use a torque wrench to tighten caliper bolts to manufacturer specifications (typically 25-30 Nm for caliper bolts).

5. Reinstall the Wheel

Place the wheel back on the hub and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a crisscross pattern to the manufacturer’s specifications (usually 120 Nm).

6. Brake Fluid Check

Refill brake fluid if necessary and ensure no leaks are present.

7. Test the Brakes

Reconnect the battery and pump the brake pedal several times to seat the new pads.
Perform a test drive to ensure proper braking performance.
