Overall Standard (4): Students will inspect, service, and repair vehicle brake systems.

 Content Understandings

Extending Understandings

Upon successful completion of these tasks students will demonstrate the ability to:

  • Explain why the brake system needs to be bled.
  • Describe symptoms caused by air in the brake system.
  • Select the tools required.
  • Locate the brake fluid reservoir.
  • Locate the bleeder valves.
  • Describe how to bleed the brake system using two persons.   

To move students towards deeper understanding, they should be given opportunities to:

  • Explain how to bleed the brake system using the one person method.
  • Explain why water in the brake fluid is dangerous.

How to Bleed a Vehicle’s Brake System – using a two person procedure

  • Safely lift the vehicle. Remove all the tires. Depending on the location of the bleeder valves the tires may not need to be removed.
  • Check the manufacturer’s specifications to see if the vehicle requires a special tool to bleed the brakes.
  • Remove old fluid from the brake fluid reservoir.
  • Fill the reservoir with new brake fluid and replace the cap – ensure there is fluid in the reservoir at all times.
  • Immediately wipe up any spilled brake fluid.
  • Bleed the brake fluid one wheel at a time – normally start with the wheel furthest from reservoir. Verify procedure and order in manufacturer’s specifications.
  • Remove the cap of the bleeder valve at the wheel.
  • Attach the tube to the bleeder valve – ensure the tube goes into a container to catch the old fluid – ensure the tube goes into the fluid so air is not sucked back in the system.
  • Loosen the bleeder valve with the wrench until fluid comes out.
  • Press down on the brakes.
  • Tighten the bleeder valve.
  • Release the brakes.
  • Repeat the above 4 steps until the fluid coming out is clear.
  • Replace the cap on the bleeder valve.
  • Refill the brake fluid reservoir.
  • Do the same steps (above 9 steps) on each wheel to bleed the brake fluid.
  • Test the brakes to be sure they operate properly.
