Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely lifted with jack stands.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Inspect and Clean the Brake Pedal Assembly

Remove the under-dash panel to access the brake pedal assembly.
Using a clean cloth, wipe down the brake pedal pivot points and any visible components to remove dirt and debris.
Apply a silicone-based lubricant to the pivot points of the brake pedal and the linkage to facilitate smooth movement.

3. Check and Replace the Brake Booster (if necessary)

Disconnect the vacuum hose from the brake booster.
Remove the master cylinder by unbolting it from the brake booster.
Inspect the brake booster for any signs of damage or vacuum leaks.
If defective, replace the brake booster by reversing the removal steps and ensuring all connections are tight.

4. Adjust the Brake Light Switch (if applicable)

Locate the brake light switch mounted on the brake pedal assembly.
Adjust the switch position so that it engages correctly when the pedal is fully depressed.
Ensure the switch is functioning properly by testing the brake lights.

5. Reassemble and Test

Reinstall the under-dash panel and reconnect the negative battery terminal.
Test the brake pedal for smooth operation.
Conduct a test drive to ensure the brakes function properly without sticking.
