my Toyota Tacoma N300 (2016-Present) brake pedal feels soft, what should I check?

Solution

1. Preparation

• Tools Required: Basic socket set, brake fluid, OBD-II scanner, safety goggles, jack and jack stands, brake cleaner.
• Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Check and Refill Brake Fluid

• Remove the master cylinder reservoir cap.
• Inspect the fluid level; if low, add the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
• Replace the cap securely.

3. Inspect for Leaks

• Visually inspect all brake lines, hoses, and connections for signs of fluid leaks.
• If leaks are found, replace damaged lines or fittings.

4. Inspect Brake Components

• Remove the wheel to access the brake assembly.
• Check the thickness of brake pads; replace if they are below the minimum thickness.
• Inspect rotors for scoring or warping and resurface or replace if necessary.

5. Test the Brake Booster

• With the engine off, pump the brake pedal several times to deplete the vacuum.
• Start the engine while pressing down on the brake pedal; the pedal should drop slightly indicating the booster is functioning correctly.
• If the pedal does not drop, the brake booster may need to be replaced.
