Solution

1. Preparation

Gather the required tools and parts.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Disconnect the battery to ensure safety during repairs.

2. Inspect and Repair Leaks

Tools Required: Wrench set, brake line tubing cutter, replacement brake lines or hoses as needed, brake fluid.
Sub-steps:
1. Visually inspect all brake lines and connections for leaks.
2. If leaks are found, replace damaged brake lines or hoses using the tubing cutter to cut the line at the damaged area.
3. Install new brake lines or hoses, ensuring all connections are tight and secure.

3. Replace or Refill Brake Fluid

Tools Required: Brake fluid, funnel.
Sub-steps:
1. If the brake fluid level is low, refill with the appropriate type of brake fluid (usually DOT 3 or DOT 4).
2. Ensure the brake fluid reservoir cap is securely replaced after refilling.

4. Bleed the Brake System

Tools Required: Brake bleeder tool or a helper, clear tubing, container for old brake fluid.
Sub-steps:
1. Attach clear tubing to the bleeder valve on the brake caliper.
2. Have a helper press the brake pedal while you open the bleeder valve to release air and fluid.
3. Close the valve before the pedal reaches the floor, then have the helper release the pedal.
4. Repeat the process until no air bubbles are visible in the fluid, moving from the furthest wheel to the nearest (usually starting with the passenger rear, driver rear, passenger front, and then driver front).
