Solution

1. Preparation

Gather tools: jack, jack stands, lug wrench, torque wrench, brake cleaner, safety glasses, gloves.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery for safety.

2. Wheel Removal

Use the lug wrench to loosen the lug nuts while the wheel is still on the ground.
Jack up the vehicle and secure it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

Inspect Brake Pads and Rotors:
- Check brake pads for uneven wear; replace if below manufacturer specifications.
- Measure rotor thickness and check for warping using a micrometer.
Replace Rotors (if warped):
- Remove caliper bolts and carefully detach the brake caliper.
- Slide off the rotor and replace it with a new one.
- Reinstall the caliper and torque bolts to manufacturer specifications (usually around 25-35 Nm).
Replace Brake Pads (if necessary):
- Remove old pads from the caliper bracket.
- Apply brake grease to the backing of new pads and install them.

4. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specification (typically around 100-120 Nm).
Reconnect the battery.

5. Brake System Bleeding (if applicable)

Bleed the brake system to remove any air bubbles.
Use a brake bleeder kit to ensure proper fluid flow and pressure.
