Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent any electrical issues while servicing the brakes.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel to access the brake assembly (use a lug wrench).
2. Inspect the brake pads for wear; replace if they are below the manufacturer’s minimum thickness.
3. Remove the caliper bolts with a socket set and carefully slide the caliper off the rotor.
4. Replace the old brake pads with new ones, ensuring they are properly seated.
5. Reattach the caliper and torque the bolts to the manufacturer’s specification (typically around 25-30 ft-lbs).

3. Inspect and Replace Brake Rotors

Sub-steps:
1. Inspect the rotors for warping or scoring.
2. If damaged, remove the rotor by taking off the caliper bracket (if applicable) and unscrewing the rotor mounting screws.
3. Install the new rotor, ensuring it is aligned properly and secure.
4. Reattach the caliper bracket and torque to the manufacturer’s specifications.

4. Check and Repair ABS Components

Sub-steps:
1. Inspect ABS wheel speed sensors for dirt or damage.
2. Clean the sensors and their mounting locations.
3. If faulty, replace the ABS sensor as per manufacturer instructions.
4. Clear any error codes using the OBD-II scanner after repairs.
