Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and set the parking brake.
Disconnect the negative battery terminal to prevent electrical issues.

2. Inspect and Clean the Brake Pedal Assembly

Remove any floor mats or items obstructing the pedal area.
Inspect the brake pedal pivot point for dirt or debris.
Clean the pivot area with a suitable cleaner and lubricate with a light grease.

3. Check and Replace Brake Fluid

Tools Required: Brake fluid syringe, funnel
Remove the brake fluid reservoir cap and check the fluid level.
If low, use a syringe to extract old fluid and refill with fresh brake fluid (DOT 3 or DOT 4 as per manufacturer specifications).
Replace the cap securely.

4. Inspect the Brake Booster

Tools Required: Vacuum gauge
Disconnect the brake booster vacuum hose and check for vacuum at idle.
If there is no vacuum, inspect the vacuum line for cracks or disconnections.
Replace the vacuum line if necessary and reconnect.

5. Test Drive the Vehicle

Reconnect the battery terminal.
Start the vehicle and gently press the brake pedal to ensure it returns to its original position.
Conduct a short test drive to assess brake responsiveness.
