Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely raise it with jack stands.
Disconnect the battery to ensure electrical safety.

2. Inspect and Replace Brake Fluid

Tools Required: Brake fluid, funnel, cloth
Sub-steps:
1. Open the master cylinder reservoir cap and check the brake fluid level.
2. If the fluid is low, fill it with the recommended brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual).
3. Clean any spilled fluid, as it can damage car paint.

3. Bleed the Brake System

Tools Required: Brake bleeder kit, socket wrench, rubber hose
Sub-steps:
1. Start with the wheel farthest from the master cylinder (usually the right rear).
2. Attach a rubber hose to the bleeder valve and place the other end in a container.
3. Have an assistant press the brake pedal several times and hold it down.
4. Open the bleeder valve until fluid starts to flow, then close it before your assistant releases the pedal.
5. Repeat until clear fluid without bubbles comes out, then move to the next wheel in order (left rear, right front, left front).

4. Inspect Brake Components

Tools Required: Brake caliper tool, socket set
Sub-steps:
1. Remove the wheel to gain access to the brake caliper.
2. Inspect the brake pads for thickness; replace if worn below 3mm.
3. Check rotors for scoring or warping; replace if necessary.
4. If pads or rotors are replaced, ensure that caliper slides are lubricated.

5. Test Brake Booster and Master Cylinder

Tools Required: Vacuum gauge, wrench
Sub-steps:
1. Start the engine and listen for a hissing sound from the brake booster.
2. With the engine running, press the brake pedal; it should feel firm after a few presses.
3. If the pedal remains soft, the master cylinder may need replacement due to internal failure.
