2
Check brake rotors for scoring, warping, or excessive wear.
3

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 prevent electrical issues.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspect: Examine the brake pads for wear; if they are less than 3 mm thick, they need replacement.
Remove: Unbolt the caliper using a socket set (typically 14mm or 15mm) and slide it off the rotor.
Replace: Remove the old brake pads from the caliper bracket and install new pads, ensuring they are properly seated.

4. Inspect and Replace Brake Rotors (if necessary)

Check: Assess the rotors for deep grooves or warping. If damaged, they must be replaced.
Remove: Unbolt the rotor from the hub using a socket set. Typically, there may be retaining screws or clips.
Install: Place the new rotor onto the hub, torque the bolts to the manufacturer's specifications (usually around 80-100 lb-ft).

5. Reassemble Braking System

Reinstall the caliper over the new brake pads and torque the caliper bolts to manufacturer specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then fully tighten the lug nuts in a crisscross pattern to the specified torque (usually around 80-100 lb-ft).

6. Final Inspection

Reconnect the battery.
Pump the brake pedal several times to seat the brake pads against the rotors.
Check the brake fluid level and top off if necessary.
