Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and set the parking brake.
Disconnect the battery to ensure safety.

2. Check and Refill Brake Fluid

Locate the brake fluid reservoir (usually near the driver's side of the engine bay).
If fluid is low, fill it with the manufacturer's recommended brake fluid type (e.g., DOT 3 or DOT 4).
Tools Required: Brake fluid, funnel.
Safety Warning: Avoid skin contact with brake fluid as it can damage paint and cause burns.

3. Inspect and Repair Leaks

If leaks are found, replace damaged hoses or components.
- For brake line repair:
  1. Remove the affected line using a wrench.
  2. Install a new line, ensuring proper fittings.
  3. Bleed the brake system to remove air.
Tools Required: Wrenches, replacement brake line, brake line flaring tool.

4. Replace Brake Components (if necessary)

If brake pads or calipers are worn:
- Remove the wheel and inspect the components.
- Replace worn brake pads or calipers as needed.
- Reassemble the wheel and torque to manufacturer's specifications.
Tools Required: Jack and jack stands, socket set, torque wrench, new brake pads/calipers.

5. Bleed the Brake System

After repairs, bleed the brake system to ensure no air is trapped.
1. Start with the wheel furthest from the master cylinder (usually the right rear).
2. Use a bleeder wrench to open the bleeder valve.
3. Have an assistant press the brake pedal while you close the valve.
4. Repeat until fluid flows without air bubbles.
Tools Required: Brake bleeder kit, wrench.
