Solution

1. Preparation

Gather 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 shorts.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Inspect Pads:
- Remove the caliper bolts using a socket wrench.
- Carefully slide the caliper off the rotor and suspend it using a bungee cord to avoid straining the brake line.
- Inspect the brake pads for wear; replace if they are less than 3mm thick.
Replace Pads:
- Remove the old pads from the caliper bracket.
- Install new brake pads, ensuring they are oriented correctly.
- Reattach the caliper over the new pads and torque the caliper bolts to manufacturer specifications (typically around 20-30 ft-lbs).

4. Inspect and Resurface/Replace Rotors

Inspect Rotors:
- Check the rotor surface for grooves or uneven wear.
Resurface or Replace:
- If the rotors are within spec, they can be resurfaced; if not, replace them.
- If replacing, remove the caliper bracket and rotor, then install a new rotor, ensuring it is properly seated.

5. Reassemble and Test

Reinstall the wheel and lower the vehicle.
Reconnect the negative battery terminal.
Pump the brake pedal a few times to seat the pads against the rotor before driving.
