Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear safety goggles and gloves.

2. Inspect and Replace Brake Fluid

Tools Required: Brake fluid, funnel, turkey baster
Remove the master cylinder reservoir cap.
Use a turkey baster to siphon out old brake fluid.
Refill the reservoir with fresh brake fluid as specified by the manufacturer (usually DOT 3 or DOT 4).
Replace the cap securely.

3. Bleed the Brake System

Tools Required: Brake bleeder kit, wrench, catch container
Begin at the furthest brake from the master cylinder (usually the right rear).
Attach the brake bleeder kit to the brake bleeder valve on the caliper.
Have an assistant press the brake pedal while you open the bleeder valve to release air and old fluid.
Close the valve before the pedal is released to prevent air from entering.
Repeat for all four wheels in the following order: right rear, left rear, right front, left front.
Ensure the master cylinder is topped off with brake fluid throughout the process.

4. Inspect and Replace Damaged Components

Tools Required: Socket set, torque wrench
Check brake lines for any signs of wear or damage; replace if necessary.
Inspect calipers for leaks; replace if leaking.
If the brake booster is faulty, disconnect the vacuum line, unbolt it, and replace it with a new unit.
Ensure all bolts are tightened to the manufacturer’s torque specifications.
