Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to prevent any electrical shorts during repairs.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel using a socket set to access the brake assembly.
2. Inspect the brake pads for wear; if they are less than 3mm thick, replace them.
3. Remove the caliper bolts with a socket wrench and carefully lift the caliper off the rotor.
4. Replace the old brake pads with new ones, ensuring they are properly seated.
5. Reinstall the caliper and tighten the bolts to the manufacturer's torque specifications (typically 25-35 Nm).

3. Brake Fluid Inspection and Replacement

Sub-steps:
1. Check the brake fluid reservoir; if low, top it off with the manufacturer-recommended brake fluid (DOT 4).
2. If fluid is discolored or contains contaminants, perform a brake fluid flush.
3. Disconnect the brake line at the caliper using a brake line wrench.
4. Bleed the brake system, starting from the furthest caliper, to remove air bubbles using a brake bleeder kit.

4. Sensor and Wiring Inspection

Sub-steps:
1. Locate the brake sensors on each wheel and inspect the wiring for frays or disconnections.
2. Use a multimeter to check the resistance of the sensors; they should fall within the manufacturer’s specifications.
3. Replace any faulty sensors or wiring as needed.

5. Reconnect Battery and Clear Codes

Sub-steps:
1. Reconnect the battery terminals securely.
2. Use the OBD-II scanner to clear any stored error codes from the system.
3. Verify that the brake warning lights have turned off.
