Solution

1. Preparation

Tools Required: Socket set, brake fluid, brake line wrench, vacuum bleeder (if available).
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Wear safety gloves and eye protection.

2. Check and Top Off Brake Fluid

Open the hood and locate the brake master cylinder.
Inspect the fluid level; if low, add the manufacturer's recommended brake fluid to the correct level.

3. Bleed the Brake System

Tools Required: Brake line wrench, vacuum bleeder (optional).
Start at the wheel farthest from the master cylinder (usually the right rear).
1. Remove the wheel for access to the brake caliper.
2. Locate the bleeder valve on the brake caliper.
3. Attach a clear hose to the bleeder valve and place the other end in a container.
4. Have an assistant press the brake pedal several times and hold it down.
5. Open the bleeder valve to allow air and fluid to escape; close the valve before the pedal is released.
6. Repeat this process until clear fluid with no air bubbles flows out, then move to the next wheel.
Ensure to keep the master cylinder reservoir topped off during this process.

4. Inspect and Replace Worn Components

If the brake pads are worn, replace them:
1. Remove the wheel and caliper, supporting it with a hangar to avoid stress on the brake line.
2. Remove the old pads and install new pads, ensuring they are properly seated.
3. Reinstall the caliper and wheel.
If the master cylinder or brake booster is faulty, replace them following the manufacturer's service manual for specific procedures.
