Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Inspection: Check the thickness of the brake pads. If they are less than 3mm, they need replacement.
Removal:
1. Locate the caliper and remove caliper bolts using a socket set.
2. Carefully lift the caliper off the rotor and secure it with a bungee cord to avoid strain on the brake line.
Replacement:
1. Remove the old brake pads from the caliper bracket.
2. Install new brake pads in the same position as the old ones.
3. Compress the caliper piston using a C-clamp to fit over the new pads.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor for grooves or warping.
Removal:
1. If the rotor needs replacement, remove the caliper bracket by unbolting it.
2. Remove the rotor from the hub.
Installation:
1. Install the new rotor and secure it to the hub.
2. Reattach the caliper bracket.

5. Reassemble and Test

Reinstall the caliper over the new pads and secure with caliper bolts.
Replace the wheel and hand-tighten lug nuts.
Lower the car and fully tighten lug nuts in a crisscross pattern to the manufacturer’s torque specifications (typically around 76 lb-ft).
Pump the brake pedal several times to seat the brake pads correctly.
