2
Check brake rotors for scoring or warping.
3
Examine brake calipers for proper operation and any sticking issues.
4

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the battery to ensure safety.

2. Remove Wheel

Use a jack to lift the vehicle and place it on jack stands.
Remove the lug nuts with a socket wrench and take off the wheel.

3. Inspect and Replace Brake Pads

Inspection: Check brake pads for thickness. If less than 3mm, they should be replaced.
Replacement:
1. Remove the caliper bolts using a socket wrench.
2. Carefully slide the caliper off the brake pads.
3. Remove old brake pads from the caliper bracket.
4. Install new brake pads into the bracket ensuring they are seated correctly.

4. Inspect and Resurface/Replace Brake Rotors

Inspection: Check rotors for deep grooves or warping.
Resurfacing:
1. If the rotors are intact but worn, use a brake lathe to resurface them.
Replacement:
1. Remove the rotor by unscrewing the retaining screws and sliding it off the hub.
2. Install new rotors, ensuring they are clean and free of debris.

5. Reassemble Braking Components

Reattach the caliper over the new brake pads.
Torque caliper bolts to manufacturer specifications (typically around 25-30 ft-lbs).
Reinstall the wheel and lug nuts, tightening them in a star pattern to ensure even pressure.

6. Final Checks

Reconnect the battery.
Pump the brake pedal a few times to ensure proper brake pad seating.
Test the brakes at low speed to confirm the noise is resolved.
