Nope, I have the standard (non ABS) brakes. You know, the Vacuum operated, non electric brakes.

So, anyone know why they used the TEVES system for a while there? Were the early ABS brake systems too vacuum hungry or something? Seems like a street engine as large as a 3.8 would produce plenty of vacuum.

Here'* a correction. It appears that the 91 did go to a vacuum assisted ABS system. In Merlin'* Black Magic, you can see the vacuum booster and line behind the master cylinder:



So would this be a correct statement?
87 - no ABS offered, vacuum assist only
88-90 - Teves with ABS; vacuum assist with no ABS
91 - Vacuum assist ABS and non ABS (if applicable)

a) yes
b) the 1988 Teves apparently had some teething problems - the return line was changed from rubber to steel in mid-88 and there seem to be two different pistons used.
c) 89-90 was the same unit used in late 88.
d) Different car lines used different shaped resovoirs apparently dependant on where the strut brace is located.
e) another difference that makes it hard to swap is that the TEVES has a single rear brake line while the vaccuum units have two.
f) Teves is a German copmany and is now part of the european Continental group where it makes braking systems for the tiny motors and diesels that are popular there.
g) VW or SAAB dealers may have parts but having the unit remaned by Prior is usuablly cheaper than buying parts.
