Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, wrench set, torque wrench, brake cleaner, safety goggles, gloves.
Ensure the vehicle is parked on a flat surface and engage the parking brake.

2. Remove Wheel

Loosen the lug nuts on the wheel with the brake issue.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper bolts.
Carefully slide the caliper off the rotor (support it to avoid straining the brake line).
Inspect the brake pads for wear. If they are worn down to the metal, replace them.
If replacing, remove the old pads and insert new pads, ensuring they are properly seated.
Apply a thin layer of brake grease to the back of the new pads to prevent noise.

4. Inspect and Replace Brake Rotor

Check the brake rotor for grooves or uneven wear. If damaged, it needs replacement.
Remove the rotor by unscrewing the retaining screws (if equipped) and sliding it off the hub.
Install the new rotor, ensuring it is aligned properly.
If reusing the rotor, clean it with brake cleaner to remove any debris or oil.

5. Reassemble Brake Components

Reinstall the caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer-recommended torque specifications (generally around 20-30 lb-ft).
Reattach the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Test

Lower the vehicle and remove the jack stands.
Tighten the lug nuts to the manufacturer's specifications (typically 75-100 lb-ft).
Pump the brake pedal a few times to seat the pads against the rotor before driving.
