i removed that ****ty old ABS system on my golf when i converted it to G60..
and i’m in the process of putting a newer system from a golf mk3 into it
much easier, and it then has ABS brakeson all 4 wheels. not only the fronts
this way i can remove that ****ing seized up brake proportion valve in the rear.
and there is way less wiring involved the ECU and everything is built into the Pump. and you also retain the Vacuum servo. so you don’t have to worry about burning up your million-drollar old abs pump
some small mods are needed tho. but they should be managable
