Solution

1. Preparation

Gather tools and ensure the vehicle is parked on a level surface.
Ensure the engine is off and the parking brake is engaged.

Tools Required:

Jack and jack stands
Lug wrench
Caliper gauge
Brake cleaner
Torque wrench

2. Remove Wheel

Loosen lug nuts using a lug wrench before lifting the vehicle.
Use a jack to elevate the car and place it securely on jack stands.
Fully remove the lug nuts and take off the wheel to access the brake assembly.

3. Inspect Brake Components

Examine brake pads for wear: replace if less than 3mm thickness is remaining.
Check the brake rotors for any grooves, scoring, or uneven wear.
If necessary, clean the rotors with brake cleaner to remove dust and debris.

4. Replace Brake Pads (if worn)

Remove caliper bolts using a socket set and carefully slide the caliper off the rotor.
Remove old brake pads from the caliper bracket.
Install new brake pads, ensuring they are positioned correctly.
Use a C-clamp to compress the caliper piston, allowing it to fit over the new pads.
Reattach the caliper to the bracket and torque bolts to manufacturer specifications (usually around 20-30 ft-lbs).

5. Reassemble and Test

Replace the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (typically around 100-150 ft-lbs).
Pump the brake pedal a few times to seat the new pads properly.
Test drive the vehicle at low speeds to ensure the noise has been eliminated.
