why does my Toyota Tacoma N300 (2016-Present) brake pedal feel spongy?

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and turn off the engine.
• Wear safety gloves and goggles.

2. Check and Refill Brake Fluid

• Tools: Brake fluid, funnel
• Open the master cylinder reservoir cap.
• Inspect the fluid level; if low, add the correct type of brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
• Replace the cap securely.

3. Inspect Brake Lines and Components

• Tools: Socket set, wrench set
• Visually inspect the brake lines for any signs of damage or corrosion.
• Tighten any loose connections.
• Replace any damaged brake lines or components as necessary.

4. Bleed the Brake System

• Tools: Brake bleeder kit, clear tubing, wrench
• Start at the wheel farthest from the master cylinder (usually the right rear).
• Attach the clear tubing to the bleeder valve and submerge the other end in a container with brake fluid.
• Have an assistant pump the brake pedal several times and hold it down.
• Open the bleeder valve to release air and fluid; close the valve before the assistant releases the pedal.
• Repeat until no air bubbles appear, then move to the next wheel (left rear, right front, left front).

5. Inspect and Replace Brake Components (if necessary)

• Tools: Torque wrench, socket set
• If brake pads are worn below the minimum thickness or rotors are warped, replace them.
• Install new brake pads and rotors, ensuring to torque bolts to manufacturer's specifications.
• Reassemble all components and ensure everything is secure.
