Solution

1. Preparation

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

2. Inspect and Replace Brake Fluid

Sub-steps:
1. Remove the brake fluid reservoir cap.
2. If the fluid is low, top it off with the manufacturer-recommended brake fluid (typically DOT 3 or DOT 4).
3. Check for any visible leaks in the brake lines and connections.

3. Bleed the Brake System

Sub-steps:
1. Attach a clear plastic tube to the bleeder valve on the brake caliper.
2. Have an assistant press the brake pedal several times and hold it down.
3. Open the bleeder valve to release air and old fluid, then close it before your assistant releases the pedal.
4. Repeat this process until no air bubbles are visible in the fluid.
5. Ensure the brake fluid reservoir remains full throughout the process.

4. Inspect and Replace Brake Components

Sub-steps:
1. Remove the wheel to access the brake assembly.
2. Inspect the brake pads; replace if they are worn down to the indicator or below the minimum thickness.
3. Check the rotors for scoring or warping; replace if necessary.
4. Reassemble the wheel and ensure all components are torqued to manufacturer specifications.
