1980 Training filmstrip for the HydroVac brake booster system used on GM's large medium duty and school busses.
This system uses a conventional master cylinder to operate dual vacuum boosters with brake hydraulic pressure. Neat!
This laserdisc is in poor condition. If I ever get another player I'll try reading it again.

Ok, I need to compliment who put this video on here. I actually used to to repair my c70 Chevy. Love, love, love the video and help! My brakes now work like a charm!

Great stuff. I am doing research to understand how to either rebuild or update (dual circuit) the brake system on my '62 Ford F600. Seems the hydrovac system was an industry standard, even for the parallel system in school buses. Thanks for posting!

Your a saint. I needed this to fix my c65.

What would cause brake fluid to be sucked back into the vacuum line to the intake? Gurgling sounds under the seat in air filter when stepping on brake pedal?

I only have one player, a Sony MDP-1100.
