Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface.
Engage the parking brake and wear safety glasses.

2. Lift the Vehicle

Use a jack to lift the front of the vehicle.
Secure the vehicle on jack stands.

3. Remove Wheels

Using a socket set, remove the lug nuts and take off the front wheels.

4. Inspect and Replace Brake Rotors

Inspection:
- Check rotors for warping using a dial indicator. If runout exceeds manufacturer specifications, they need replacement.
Replacement:
- Remove caliper bolts with a socket set.
- Carefully slide the caliper off the rotor and support it (do not hang by the brake line).
- Remove the rotor by taking off the retaining screws, if present.
- Install the new rotor and torque the screws to manufacturer specifications.

5. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Inspect the caliper for leaks or damage.
Apply brake grease to the back of the new pads and install them in the caliper bracket.

6. Reassemble Components

Reattach the caliper over the new pads and torque the caliper bolts to manufacturer specifications.
Reinstall the wheels and torque lug nuts in a star pattern.

7. Final Checks

Lower the vehicle and pump the brake pedal to seat the pads.
Check brake fluid levels and add fluid if necessary.
