Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the negative battery terminal to prevent any electrical issues during repair.

2. Remove Wheel

Use a jack to lift the front or rear of the vehicle, depending on which brakes are being serviced.
Secure with jack stands.
Remove lug nuts using a socket wrench and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Components:
- Check the brake caliper for leaks and damage.
- Assess brake rotor condition, measuring thickness and checking for grooves.
Remove Caliper:
- Use a socket wrench to remove the caliper mounting bolts.
- Carefully slide the caliper off the rotor and support it using a bungee cord or wire to avoid strain on the brake line.
Remove Old Brake Pads:
- Slide out the old brake pads from the caliper bracket.
Install New Brake Pads:
- Apply brake grease to the backing of the new pads to prevent squeaking.
- Install the new pads into the caliper bracket.

4. Reassemble Brake Components

Reattach Caliper:
- Carefully slide the caliper back over the new pads and rotor.
- Reinstall caliper bolts and torque to manufacturer specifications (typically around 20-30 ft-lbs).
Reinstall Wheel:
- Place the wheel back onto the hub and hand-tighten the lug nuts.
- Lower the vehicle and then fully tighten the lug nuts in a criss-cross pattern to ensure even pressure.

5. Final Checks

Reconnect the negative battery terminal.
Pump the brake pedal several times to ensure proper pad seating and brake pressure.
