Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the battery to avoid any electrical issues.

2. Remove Wheel

Loosen lug nuts with a socket and wrench.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Locate the brake caliper and remove the caliper bolts with a socket.
Carefully slide the caliper off the rotor and suspend it using a bungee cord or rope to avoid straining the brake line.
Remove the old brake pads from the caliper bracket.
Check the caliper slides for movement; lubricate if necessary.
Install new brake pads, ensuring they are properly aligned.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for grooves or damage. If worn beyond specifications, replace the rotor.
If replacing, remove the rotor by removing the retaining screws (if applicable) and slide it off the hub.
Clean the hub surface with a wire brush to ensure proper seating of the new rotor.
Install the new rotor, securing it with screws if required.

5. Reassemble Brake Components

Reinstall the brake caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer’s specified torque (usually around 25-35 ft-lbs).
Reinstall the wheel and tighten the lug nuts in a star pattern to the specified torque (usually around 76 ft-lbs).

6. Final Checks

Lower the vehicle and reconnect the battery.
Pump the brake pedal a few times to seat the pads against the rotor.
Check brake fluid level and top off if necessary.
