make sure u read my post on brake bleeding
ur even though ur using a vacumme system, u may stil have leaks that would make it useless
if u have a handpump type vacumm system, when u build the pressure up make sure the pressure gauge shows that it's maintaining it's pressure, if it's not, means the tubes might be too big for the nipples. When u crack open the nipple valve, fluid will come out BUT... Ur pressure gauge should still be still with no loss of pressure. If there's loss, then this is your problem so listen up...
Your nipple valves are leaking, u need to buy some plumbing tape(Teflon tape) preferbly the one for gas. There are 2 types, 1 for water plumbing, the other for gas.
Remove the nipple valve, dry it with cloth, apply about 3 rounds of gas Teflon tape(5 rounds for water Teflon tape). Screw it back in. Apply the vacumme tube, build the pressure up to max, then crack open the valve 180degrees, the pressure on gauge should not move at all, if it does then reapply the Teflon tape as u might have done it wrong, or might just need more.
Once you dont see anymore bubbles, close the valve and your done. You need to remember the order for FWD cars are diff from RWD.
FWD is closest side to master cylinder, which is front right
then left rear
then front left
then right rear
this is for right hand drive cars
All my cars have some seriously short pedal travel b4 the pads bite, the pedal only travels an inch b4 biting hard. Super braking response I would say.
1 important thing I forgot to mention is, before u crack open the valve for each corner, jump into the drivers seat, step on the brake pedal a few times until the pressure is built up, then hop down and presume with the bleed. Do this for each corner.
Goodluck, some others will tell u differently, but I know what my brake pedal feels like. And even my gf was shocked at how little pedal travel it takes to slow the car down
enjoy

p.s I don't mind if u post this info on the forums to help others
