Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a level surface and secure with wheel chocks.
Disconnect the negative battery terminal to prevent electrical issues.

2. Remove Wheels

Tools Required: Jack, jack stands, lug wrench.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheels for access to the brake components.

3. Inspect and Replace Brake Pads and Rotors

Inspect the brake pads for uneven wear; replace if thickness is below specifications (usually less than 3mm).
Inspect the rotors for warping using a run-out gauge; replace if warping exceeds manufacturer specifications (typically 0.002 inches).
If replacing, remove caliper bolts and slide the caliper off the rotor.
Remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
Install the new rotor and reattach the caliper, ensuring all bolts are torqued to manufacturer specifications (typically 85-95 ft-lbs).
Replace the brake pads, ensuring they are seated properly in the caliper bracket.

4. Reassemble and Test

Reattach the wheels and torque the lug nuts to manufacturer specifications (usually around 100-110 ft-lbs).
Reconnect the negative battery terminal.
Lower the vehicle from the jack stands.
