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 negative battery terminal to prevent electrical issues while servicing.

2. Remove Wheel

Tools Required: Jack and jack stands, lug wrench.
Loosen the lug nuts on the wheel before raising the vehicle.
Use the jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Check the thickness of the brake pads; if they are worn below 3mm, replace them.
Sub-steps:
1. Remove the caliper bolts using a socket wrench.
2. Carefully slide the caliper off the rotor without stretching the brake line.
3. Remove old brake pads from the caliper bracket.
4. Install new brake pads, ensuring they are correctly oriented.
5. Reattach the caliper and torque the caliper bolts to manufacturer specifications (typically 25-35 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotors for grooves or warping.
If damaged, replace the rotors.
Sub-steps:
1. Remove the caliper bracket if necessary.
2. Remove the rotor by unscrewing any retaining screws and pulling it off the hub.
3. Install the new rotor and secure it with retaining screws.
4. Reinstall the caliper bracket.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to manufacturer specifications (usually 100-120 ft-lbs).
Reconnect the battery terminal.
Pump the brake pedal several times to ensure proper pressure.
