Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Place wheel chocks behind the rear wheels for safety.

2. Check and Replenish Brake Fluid

Sub-steps:
- Locate the brake fluid reservoir under the hood.
- Inspect the fluid level; if low, top it off with manufacturer-recommended brake fluid (usually DOT 3 or DOT 4).
Tools Required: None specifically for this step.

3. Inspect and Repair Brake Lines

Sub-steps:
- Visually inspect all brake lines and hoses for cracks, corrosion, or leaks.
- If leaks are found, replace damaged lines or hoses.
- Ensure all connections are tight and secure.
Tools Required: Wrench set, brake line flaring tool if necessary.

4. Bleed the Brake System

Sub-steps:
- Start with the brake furthest from the master cylinder (usually the right rear).
- Attach a clear plastic hose to the bleeder valve on the brake caliper.
- Ask an assistant to press the brake pedal while you open the bleeder valve to release air and fluid.
- Close the bleeder valve before the pedal is released, and repeat until no air bubbles are seen.
- Move to the next brake and repeat the procedure for all four brakes.
Tools Required: Bleeder kit, clear tubing, wrench for bleeder screws.
Safety Warnings: Ensure the brake fluid does not touch paintwork as it may cause damage.

5. Check Brake Components

Sub-steps:
- Remove wheels to inspect brake pads, rotors, and calipers.
- Replace any worn brake pads and ensure rotors are not warped or damaged.
- Reassemble everything securely after inspection.
Tools Required: Socket set, torque wrench for wheel bolts.
