1999 Astro Van brake booster (hydro-boost) flushing and bleeding

This video shows how I flushed the power brake/power steering system after replacing the power boost unit (hydro-boost). This does not show how to replace the hydro-boost unit, because there are multiple videos that show how to do that. I did not want to contaminate the new hydro-boost unit with the dirty fluid in the system. The procedure used accomplishes that goal.

Thanks for the comment.

I have the same car, when i hold the brake and turn the steering wheel the car vibrates and the battery level starts to drop and the car shuts off. Is this a hydro booster problem?

[@diywithdave3186]

With mine there was oil everywhere under the hood. I didn't have the specific issue you describe. The driver in our situation lost braking assist and power steering at the same time, all of a sudden.

DIY with Dave I love that passage in John 15

[@diywithdave3186]

I agree, the whole chapter is great.

I need to go back to church. Im backsliding.

I thought to bleed the power steering and hydroboost you needed a vacuum pump pull the air out of the system

[@diywithdave3186]

That would make it easier, but the method I used works if you don't have a vacuum pump.

A comedy.
