Solution

1. Preparation

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

2. Remove Wheel

Use a lug wrench to loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel to access the brake components.

3. Inspect Brake Pads and Rotors

Remove the caliper bolts using a socket set and carefully slide the caliper off the rotor.
Check the brake pads for thickness; replace if they are below the manufacturer’s minimum specification (usually around 3mm).
Inspect the rotor surface for grooves or uneven wear; if the surface is damaged, it may need to be resurfaced or replaced.

4. Replace Brake Pads (if necessary)

If brake pads are worn, install new pads by placing them into the caliper bracket.
Apply brake lubricant to the backing of the new pads to prevent squeaking.
Reinstall the caliper over the new pads and secure it with the caliper bolts, tightening to manufacturer specifications.

5. Check and Replace Rotors (if necessary)

If rotors are scored or warped, replace them. Remove the old rotor by unscrewing any retaining screws and sliding it off the hub.
Install the new rotor by sliding it onto the hub and securing it with the retaining screws if applicable.

6. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and use the lug wrench to securely tighten the lug nuts in a star pattern.
Test the brakes by gently pressing the brake pedal to ensure proper engagement.
