Diagnostic Steps

1
Inspect brake pads for wear: Remove the wheel and visually check the thickness of the brake pads.
2
Examine brake rotors: Look for scoring, grooves, or warping on the rotor surface.
3
Check brake fluid level: Ensure the brake fluid reservoir is at the appropriate level.
4
Inspect calipers: Look for sticking or seized calipers that may prevent proper pad contact.
5
Test for debris: Check for any dirt, dust, or debris lodged between the brake components.

Solution

1. Preparation

Gather tools: Socket set, jack stands, lug wrench, brake cleaner, and safety goggles.
Ensure the vehicle is on a level surface and the parking brake is engaged.

2. Remove Wheel

Loosen lug nuts with the lug wrench.
Use the jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect & Replace Brake Pads

Inspect Pads: Check the thickness of the brake pads. If they are below 3mm, replace them.
Remove Old Pads: Unbolt the caliper from the bracket using a socket set. Slide the caliper off the rotor.
Replace Pads: Slide the new brake pads into the caliper bracket. Ensure they are oriented correctly.

4. Inspect & Replace Brake Rotors (if needed)

Remove Rotors: If rotors are damaged, remove the caliper bracket and then unbolt the rotor from the hub.
Install New Rotors: Place the new rotor onto the hub and secure it with the bolts to the specified torque (typically around 80-100 ft-lbs).

5. Reassemble and Test

Reattach Caliper: Place the caliper back over the new pads and rotor, and bolt it in place.
Reinstall Wheel: Place the wheel back on, hand-tighten the lug nuts, lower the vehicle, and then torque the lug nuts to the manufacturer’s specification (generally 80-100 ft-lbs).
Test the Brakes: Start the vehicle and press the brake pedal several times to seat the new pads.
