Solution

1. Preparation

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

2. Inspect and Replace Brake Fluid

Remove the brake fluid reservoir cap and inspect the fluid for contamination or low levels.
If fluid is contaminated, siphon out the old fluid using a turkey baster.
Refill the reservoir with fresh brake fluid meeting the manufacturer’s specifications (DOT 3 or DOT 4).
Replace the reservoir cap securely.

3. Inspect and Replace Brake Booster

Locate the brake booster, which is typically mounted on the firewall.
Disconnect the vacuum line from the brake booster.
Unbolt and remove the brake booster from the firewall.
Install the new brake booster by reversing the removal process, ensuring all connections are tight.
Reconnect the vacuum line securely.

4. Bleed Brake System

Start by locating the brake bleed screws on each brake caliper.
Have a helper pump the brake pedal several times to build pressure, then hold the pedal down.
Open the bleed screw to release air and brake fluid, then close it before the pedal is released.
Repeat this process until no air bubbles are present in the fluid.
Ensure the brake fluid level remains adequate throughout the bleeding process.
