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.
Wear gloves and safety glasses.

2. Inspect and Replace Brake Fluid

Sub-steps:
1. Open the hood and locate the brake master cylinder.
2. Check the brake fluid level; if low, top it off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
3. If the fluid is dark or contaminated, proceed to replace the brake fluid.

3. Bleeding the Brake System

Sub-steps:
1. Start at the brake farthest from the master cylinder (usually the right rear).
2. Attach a clear hose to the bleeder screw on the brake caliper and place the other end into a container.
3. Have an assistant pump the brake pedal several times and hold it down.
4. Open the bleeder screw to release air and brake fluid, then close it before your assistant releases the brake pedal.
5. Repeat this process until no air bubbles are visible in the fluid.
6. Move to the left rear, then right front, and finish with the left front brake.

4. Inspect Brake Components

Sub-steps:
1. Remove the wheel to access the brakes.
2. Inspect the brake pads for wear; replace them if they are below the minimum thickness.
3. Check the rotors for scoring or warping; resurface or replace if necessary.
4. Inspect calipers for proper operation and leaks; replace if defective.

5. Test the Brake Booster

Sub-steps:
1. With the engine off, pump the brake pedal until it feels firm.
2. Start the engine while keeping pressure on the brake pedal; it should sink slightly as the brake booster activates.
3. If it does not, further diagnose the booster for vacuum leaks or failure.
