Solution

1. Preparation

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

2. Inspect and Replace Brake Fluid

Sub-steps:
1. Locate the master cylinder reservoir and remove the cap.
2. Check the brake fluid level; if low, add the appropriate type of brake fluid (DOT 3 or DOT 4).
3. If the fluid appears dirty or contaminated, proceed to replace it.

Tools Required: Brake fluid (DOT 3 or DOT 4), funnel

3. Check for Brake Line Leaks

Sub-steps:
1. Visually inspect all brake lines for signs of corrosion or damage.
2. Check the brake calipers and wheel cylinders for fluid leaks.
3. If any leaks are found, replace the damaged components or brake lines.

Tools Required: Wrench set, brake line replacement kit

4. Bleed the Brake System

Sub-steps:
1. Start with the wheel farthest from the master cylinder (usually the rear right).
2. Attach a clear hose to the bleeder screw on the brake caliper and place it in a container.
3. Have an assistant pump the brake pedal several times and hold it down.
4. Open the bleeder screw to let air and old fluid escape, then close it before the pedal is released.
5. Repeat the process until no air bubbles are present in the fluid.
6. Move to the next wheel and repeat.

Tools Required: Brake bleeder kit, wrench

5. Inspect Brake Pads and Rotors

Sub-steps:
1. Remove the wheel to gain access to the brake components.
2. Inspect the brake pads for thickness; replace if worn down to the minimum thickness.
3. Check the condition of the rotors for warping or scoring; resurfacing or replacement may be necessary.

Tools Required: Socket set, brake pad gauge, rotor measurement tool
