Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and set the parking brake.
Disconnect the negative battery terminal to avoid electrical shocks.

2. Addressing Error Codes

Sub-step 1: Connect the OBD-II scanner to the vehicle's diagnostic port and clear any error codes.
Sub-step 2: After clearing, take the vehicle for a short drive to see if the codes return.

3. Brake Fluid Inspection and Replacement

Sub-step 1: Remove the brake fluid reservoir cap and inspect the fluid. If it is dark or contaminated, proceed to replace it.
Sub-step 2: Use a brake fluid bleeder kit to remove old fluid from the system.
Sub-step 3: Fill the reservoir with the recommended brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual).

4. Brake Pad and Rotor Replacement

Sub-step 1: Lift the vehicle and secure it with jack stands. Remove the wheel to access the brake components.
Sub-step 2: Remove the caliper bolts with a socket set, carefully detach the caliper, and hang it without stressing the brake line.
Sub-step 3: Remove the old brake pads and inspect the rotor for scoring or warping. Replace if necessary.
Sub-step 4: Install new brake pads and reattach the caliper, ensuring all bolts are torqued to the manufacturer’s specifications.

5. Bleeding the Brake System

Sub-step 1: Start at the wheel farthest from the master cylinder and work towards the closest.
Sub-step 2: Use a brake bleeder tool to open the bleeder valve while an assistant presses the brake pedal.
Sub-step 3: Close the valve before the assistant releases the pedal to avoid air intake. Repeat until no air bubbles are seen in the fluid.
