I have one of the hand operated ones by MityVac. You really have to pump the shit out of it to pull enough vacuum. Make sure you are using the right fitting on the bleeder so youre not losing any of the vacuum.
I usually put it on the bleeder, pump it several times, walk around to the brake pedal and press it a couple times, and then go back to the bleeder and pump the shit out of the vacuum pump.
Even though it doesn't work that great, it is still one of the best tools I have ever purchased.
Hope I can post this here. I have deal setup with EGR Sever Service brakes and they are currently offering pressure bleed kits for $150. Problem is, the deal is over today 2/28 (wish I would have seen this post earlier). The regular price is $189 or $199 for the kit.
You can make a pressure bleeder out of a metal plate, a piece of rubber floor mat and a valve stem. Drill the hole for the valve stem and cut the rubber to make the gasket. Use a C-clamp to hold the plate on the master cylinder and a bicycle pump for the valve stem.
My mityvac is a hit & miss deal. Sometimes it works great, other times it's crap. But I still won't give up my mityvac. It worked good on my moded XJ good enough to throw my coffee cup (full) to the dash on a sudden emergency stop.
