Solution

1. Preparation

Gather all tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to ensure safety.

2. Remove Wheel and Brake Components

Using a jack, lift the front of the vehicle and secure it with jack stands.
Remove the wheel by loosening lug nuts with a socket set.
Inspect the brake caliper for any damage and remove it by unscrewing the caliper bolts.
Take off the brake pads and inspect their condition.

3. Inspect and Replace Brake Rotors (if necessary)

Measure the rotor thickness using a micrometer; if below minimum specifications, replace.
If warped, remove the rotor by unscrewing the rotor retaining screws (if equipped) and pulling it off the hub.
Install new rotors, ensuring they are torqued to the manufacturer's specifications.

4. Reassemble Brake Components

Place the new or inspected brake pads back into the caliper bracket.
Reinstall the brake caliper over the pads. Ensure caliper bolts are tightened to the specified torque.
Reinstall the wheel and hand-tighten the lug nuts.

5. Final Checks

Reconnect the battery.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.
Test the brakes by pressing the pedal a few times to seat the pads against the rotors.
