You asked about the vac first before injection.

If you ever saw someone working on an AC unit on a car, To get the freon in the AC unit they FIRST have to pull a vacum to get as much air out of the unit, then hold the can of freon up, fluid at the bottom and release the freon in the AC unit fluid first. In an AC uint they do not force the freon in, it is just from the vacum equalizing at that point.

With a vac first repair system from GT "Spectrum" it is moreless the same, but we help it a long with a little presure and than draw one more vac / presure... You can not do that with an AC unit in a car though.

With the GT Specrum I will pull a vac, and still under vac I will turn the injector to dump reisn into the break and wait a few, then release the vac then plung down on the injector to fill the break... You can see the resin filling before I even start injecting...
I let the customers watch and they are amazed, even the older folks. I like to let them watch then they tell their freinds. That is how I get a lot of jobs.

It is easer to pull a vac with out having resin in the break and it is faster..

I hope that helps for what I know of it.

I am a hard nut to sell when buying something. I will tell you, it sold me.

NOTE: I am not selling the product, just stating what I felt using the system... I started with Novus, then the 20/20 to the prizm, and now the spectrum.
Oh ya, I do have a LR just for vert. repairs.

Don.
