Help please

u can chose the to put a hose on the really big vac nipple on the uim or use the hose that comes of the master cylinder.
just dont suck all the water in right away, do it little by litlle while giving it gas

Here is what I have done (effectivly)

USE SEAFOAM

follow the hose that goes from the brake booster accross the back of the firewall then returns to rubber and goes to the uim

pull the hose off the metal line and pour in 1 can of seafoam
shut the car off wait 5 minutes
start the car up and go drive the piss out of it until the seafoam is gone and the car stops smoking..

Using that hose will only get the rear rotor. You need to use the location that feeds both the front and rear rotor at the same time. This location is from the MAP sensor located on the passenger side strut tower.

no that will toss it into the uim which will get it distributed to both housing. (this was found to be true after I tore my engine down)

it may not get distributed evenly but it does the trick.
