[ALFAROMEO1]

i have a 1984 alfa romeo spider..undergoing an engine conversion...i am upgrading the oem brake to 12.19 vented disk 2 peice type on all 4 corners..but i am also using the calipers( 4 ) from a boxster.. the oem ( alfa romeo ) master cly will push the fluild i need to stop the car.. so i am/ have installed a master brake cly from( new ) 2000 boxster.... no power boost...no room for it.. so have any of you disconnected the power boost from your system and stopped the car..my spider weighs in at 2380 pounds

The Boxster master cylinder is designed to be supported by the vacuum booster; it will not work well without it.

most modern car are designed to run with out a booster..my alfa rpider on oem brakes did also,, but i disconected the hose and pluged it,, and it worked fine,,just a little more leg on it
