why does my Toyota Tacoma N300 (2016-Present) have a hard brake pedal

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and secured with wheel chocks.
• Disconnect the negative battery terminal to avoid electrical shorts.

2. Check and Refill Brake Fluid

• Remove the master cylinder reservoir cap.
• Inspect the brake fluid level; if low, top off with the appropriate DOT brake fluid.
• Replace and securely fasten the cap.

3. Inspect and Replace Brake Booster

• Disconnect the vacuum line from the brake booster.
• Remove the bolts securing the brake booster to the firewall.
• Detach the master cylinder from the brake booster (may require removal of brake lines; use caution to avoid fluid spills).
• Install the new brake booster by reversing the removal steps, ensuring all connections are tight and secure.

4. Test Brake System

• Reconnect the negative battery terminal.
• Start the engine and press the brake pedal to ensure the pedal feels normal.
• Check for leaks around the master cylinder and booster connections.
• Conduct a test drive to ensure proper brake function.
