Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, brake cleaner, mechanic’s gloves, safety goggles.
Safety Warnings: Ensure the vehicle is on a flat surface and secured with jack stands before working underneath.

2. Remove Wheel

Loosen the lug nuts with a lug wrench while the vehicle is still on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Rotors

Check the rotors for warping using a dial indicator.
If warped, remove the caliper by unscrewing the caliper bolts and hanging it using a bungee cord.
Remove the rotor by unscrewing the retaining screws, if applicable.
Install new rotors, ensuring they are clean and free from grease.
Torque the retaining screws to the manufacturer’s specifications.

4. Inspect and Replace Brake Pads

While the caliper is off, inspect the brake pads for wear. Replace if thickness is below 3mm.
Remove the old brake pads and clean the caliper bracket.
Apply brake grease to the back of the new pads and install them in the caliper bracket.

5. Reassemble Components

Reattach the caliper over the new pads and torque the caliper bolts to the manufacturer’s specifications.
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Lower the vehicle from the jack stands and remove the jack.
Torque the lug nuts to the manufacturer’s specifications in a crisscross pattern.
Test the brakes by pressing the pedal several times to ensure proper engagement.
