how to troubleshoot the brake system on my Toyota Tacoma N300 (2016-Present)?

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
• Disconnect the battery for safety.

2. Brake Fluid Inspection and Replacement

• Sub-steps:
  • Remove the brake fluid reservoir cap.
  • Check fluid condition; if dirty or contaminated, proceed to replace.
  • Use a brake fluid syringe to remove old fluid from the reservoir.
  • Refill with new brake fluid (DOT 3 or DOT 4 as specified).
  • Reinstall the cap securely.

3. Brake Pad and Rotor Replacement

• Tools Required: Socket set, torque wrench, brake caliper tool, jack and jack stands.
• Sub-steps:
  • Loosen the lug nuts and lift the vehicle with a jack; secure it with jack stands.
  • Remove the wheel to access the brake components.
  • Use a socket to remove the caliper bolts and slide the caliper off the rotor.
  • Remove the old brake pads from the caliper bracket.
  • Inspect the rotor for wear; replace if warped or below minimum thickness.
  • Install new brake pads into the caliper bracket and compress the caliper piston using a brake caliper tool.
  • Reattach the caliper and torque the bolts to the manufacturer's specifications (usually around 20-30 ft-lbs).
  • Reinstall the wheel and lower the vehicle.

4. Brake Line Inspection and Repair

• Sub-steps:
  • Inspect all brake lines for damage or corrosion.
  • If leaks are detected, use a line cutter to remove the damaged section and replace it with new brake line tubing.
  • Ensure all connections are tight and use brake line fittings as needed.
