Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and the engine is off.
Wear safety gloves and goggles.

2. Inspect and Replace Brake Fluid

Sub-steps:
1. Remove the master cylinder cap.
2. Check the brake fluid for contamination or low level; top off with approved brake fluid (DOT 4).
3. If fluid is contaminated, proceed to flush the brake system.

Tools Required: Brake fluid, funnel

3. Bleed the Brake System

Sub-steps:
1. Locate the bleeder valves on each brake caliper.
2. Attach a clear hose to the bleeder valve and place the other end into a container with brake fluid.
3. Have an assistant press the brake pedal while you open the bleeder valve; close it once fluid flows out without air bubbles.
4. Repeat for each caliper until all air is removed.

Tools Required: Bleeder wrench, clear tubing, brake fluid container

4. Inspect and Replace Brake Components

Sub-steps:
1. Remove the wheel to access the brake assembly.
2. Inspect brake pads for wear; replace if they are below the minimum thickness.
3. Check rotors for scoring; replace if necessary.
4. If the brake pads or rotors are worn, remove the caliper and replace components.

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench

5. Test Brake Booster

Sub-steps:
1. With the engine running, press the brake pedal; it should feel firm.
2. If the pedal sinks with the engine running, the brake booster may need replacement.

Tools Required: Vacuum gauge (optional)
