[V6-12v] stopping problems

[mike]

for what it’s worth
I’ve just checked the actual
hardware on my car (UK V6 80q 1993) and there is
definitely no vacuum assist and it does have the bomb
and two stage ps pump. 

Also noticed there are various vacuum reservoirs
scattered around but the brakes are purely hydraulic
