Solution

1. Preparation

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

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheels to access the brake components.

3. Inspect and Replace Brake Pads

Inspect Pads: Check the thickness of the brake pads; if they are less than 3mm, replace them.
Remove Caliper: Use a socket set to remove the caliper bolts and gently slide the caliper off the rotor.
Remove Old Pads: Pull out the old brake pads from the caliper bracket.
Install New Pads: Place new brake pads into the caliper bracket, ensuring they are aligned correctly.

4. Inspect and Replace Brake Rotors

Check Rotors: Inspect rotors for deep grooves or warping; if damaged, replace them.
Remove Rotor: If necessary, remove the retaining screws and gently slide the rotor off the hub.
Install New Rotor: Position the new rotor onto the hub and secure with screws.

5. Reassemble Braking System

Reattach Caliper: Slide the caliper back over the new pads and rotor. Torque the caliper bolts to manufacturer specifications (typically around 25-30 ft-lbs).
Reinstall Wheels: Place the wheels back on and hand-tighten the lug nuts.

6. Final Checks

Reconnect Battery: Reconnect the battery terminals.
Check Brake Fluid: Ensure the brake fluid is at the proper level and top off if necessary.
