Five Minute Fix 55 - Brake Booster Check Valve Testing and Replacement 1997 Ford E-150 Econoline Van

Welcome! In this Five Minute Fix video I show how to remove, test and replace the check valve of a power brake booster on my 1997 Ford E-150 Econoline Van named Engima. I know that I have a leak in my power brake booster system somewhere, so this is the fast and cheap first step to finding out where the problem is. Ultimately the valve is good, the booster itself is bad.

Thanks for the video!

This video is doing surprisingly well. Who knew that the Internet wanted to see me blow into a check valve? I have also released the companion video to this where I replace the power brake booster.

Clean and treat the grommet with wd-40.
It works great on rubber. If you are changing an old tire for a used one, treat around and clean the tire that touches metal. You will see the difference. It may not a permanent solution but a good quick fix. Try it on some rubber product

I'll keep that in mind. In this case the booster was definitely bad. I don't have the video up yet, but I've changed it out and it is now performing how I would expect.

@@flxrix6913 You mean actual hydraulic braking pressure? The pedal does not stay firm and sinks to the floor with the engine off? If that is happening you probably have a leak in your braking system somewhere and air has gotten into the line. You'll need to find and address your leak before worrying about the brake booster.
