Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a flat, stable surface and engage the parking brake.

2. Lift the Vehicle

Use a jack to lift the front of the vehicle and secure it with jack stands.
Remove the front wheels using a socket set.

3. Inspect and Replace Brake Rotors

Inspect Rotors: Use a dial indicator to check for warping. If warped beyond spec, replace.
Remove Old Rotors: Unbolt the caliper from the bracket and hang it using a bungee cord. Remove the rotor retaining screws if equipped, then slide off the rotor.
Install New Rotors: Clean the hub surface and slide the new rotor onto the hub. Secure with retaining screws.

4. Replace Brake Pads

Remove Caliper Bracket: Unbolt the caliper bracket from the steering knuckle.
Remove Old Brake Pads: Slide the old pads out of the bracket.
Install New Brake Pads: Apply brake grease to the back of the new pads and install them into the caliper bracket.

5. Reassemble Components

Reattach Caliper: Position the caliper over the new pads and bolt it back to the bracket.
Reinstall Wheels: Place the wheels back on, hand-tighten the lug nuts, then lower the vehicle and torque the lug nuts to the manufacturer's specifications.

6. Final Checks

Pump the brake pedal to ensure proper brake pad seating.
Check brake fluid level and top off if necessary.
