Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery to avoid electrical issues.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel using a lug wrench.
Tools Required: Jack, jack stands, lug wrench.

3. Inspect and Replace Brake Components

Inspect Brake Rotors

Remove the brake caliper by unbolting it from the bracket.
Carefully hang the caliper using a bungee cord to avoid stress on the brake line.
Remove the brake rotor. Check for warping using a dial indicator.
If warped, replace the rotor.

Inspect Brake Pads

Check the thickness of the brake pads. Replace if less than 3mm.
Clean the caliper bracket and apply anti-squeal grease to the back of the pads (if applicable).

4. Reassemble

Reinstall the brake rotor and then the caliper.
Ensure all bolts are torqued to manufacturer specifications.
Reinstall the wheel and lower the vehicle.

5. Test Brake System

Reconnect the battery.
Pump the brake pedal a few times to ensure proper brake function before driving.
