Brake Booster Master Cylinder Line

[Dubkayc]

Hey guys, I tried to disconnect the master cylinder brake line but there was a lot of fluid that came gushing out.

Is this the correct one back here to the right? In various YT videos, it’s to the left of the reservoir.

I’m trying to run Seafoam thru it.

Hydroboost? That should be power steering fluid. Where's the soft line end up -- at the PS pump, right?

Not a vacuum line.

thats your hydro boost brakes, no vacuum there. you need to pull a vac line off the engine and suck it in via that line.

Why are you trying to run Seafoam thru a vacuum line to engine? If you did not know you have hydro boost, you better be clear why and what you are doing.

Well i read that it works best with the brake booster or vacuum lines, just need to find one at this point.

The other suggestion was to insert the straw into the throttle body and spray there while revving to 2k rpm.

pull the hose off from the pcv off and let it eat through that.
