Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to avoid any electrical issues during the repair.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel lug nuts with a socket wrench.
Take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper by unbolting it from the bracket.
Carefully slide the caliper off the rotor and support it (do not let it hang by the brake line).
Remove the old brake pads from the caliper bracket.
If pads are worn down to the metal backing, replacement is necessary.
Install new brake pads, ensuring they are properly seated.

4. Inspect and Replace Brake Rotors (if necessary)

Check rotors for any signs of damage such as grooves or warping.
If rotors are damaged, remove them by unbolting from the hub.
Install new rotors, ensuring they are properly torqued to manufacturer specifications (typically 80-100 ft-lbs).
Clean rotor surfaces with brake cleaner to remove any oil or debris.

5. Reassemble Brake Components

Reattach the caliper over the new brake pads.
Tighten caliper bolts to manufacturer specifications (typically 25-35 ft-lbs).
Reinstall the wheel and tighten lug nuts in a star pattern to ensure even pressure.

6. Final Checks

Reconnect the battery.
Lower the vehicle from the jack stands.
Pump the brake pedal a few times to seat the pads against the rotor.
