2
Check the condition of the brake rotors for scoring or warping.
3

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Remove Wheel

Use a lug wrench to loosen lug nuts.
Raise the vehicle using a jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Locate the brake caliper and remove the caliper bolts using a socket set.
Carefully slide the caliper off the brake rotor and suspend it using a bungee cord to avoid stress on the brake line.
Remove the old brake pads and inspect for wear; replace if worn down to the indicator.
Apply brake grease to the back of the new brake pads to prevent noise.

4. Inspect and Replace Rotors (if necessary)

Check the rotor surface for scoring; if damaged, remove the rotor by unscrewing the retaining screws (if equipped) and sliding it off the hub.
Install the new rotor, ensuring it is properly aligned and secured.
If reusing rotors, consider having them resurfaced to eliminate any imperfections.

5. Reassemble Braking System

Reinstall the brake caliper over the new brake pads and rotor, and secure it with the caliper bolts. Torque the bolts to the manufacturer’s specifications (usually around 25-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Final Checks

Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (typically 76 ft-lbs).
Reconnect the negative battery terminal and check the brake fluid level; top off if necessary.
