Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Safety warning: Disconnect the battery if working on electronic brake systems.

2. Inspect and Replace Brake Rotors

Remove Wheel
- Tools Required: Jack, jack stands, lug wrench
- Loosen lug nuts, lift the vehicle, and secure with jack stands. Remove the wheel.
Inspect Brake Rotors
- Visually check for warping, scoring, or uneven wear.
- Use a dial indicator to measure runout; if over specifications, proceed to replace.
Remove Brake Caliper
- Tools Required: Socket set, torque wrench
- Unbolt and remove the caliper from the rotor (do not disconnect the brake line). Secure it using a bungee cord or suitable support.
Remove Brake Rotor
- If necessary, tap the rotor gently with a hammer to dislodge it.
Install New Brake Rotor
- Clean the new rotor with brake cleaner to remove any protective coating. Install it on the hub.

3. Replace Brake Pads

Remove Old Brake Pads
- Check the caliper bracket for any debris and clean if necessary. Remove old brake pads from the caliper.
Install New Brake Pads
- Apply brake grease to the backing of the new pads. Install them into the caliper bracket.
Reinstall Caliper
- Reattach the caliper over the new pads and torque the bolts to manufacturer specifications.

4. Reassemble and Test

Reinstall Wheel
- Place the wheel back on, hand-tighten the lug nuts, lower the vehicle, and then torque the lug nuts to specifications.
Test Brakes
- Before driving, pump the brake pedal to ensure proper engagement of the pads and rotors.
