Hey guys, I'm replacing my brake master cylinder, and booster, along with front lines and hoses, as my brakes have been going almost to the floor lately.
I know it was leaking somewhere but not exactly sure as to where. Anyway, I bought a spare brake booster off a facelift 318i to replace mine (pre-facelift 1987 320i), but upon taking my booster and cylinder out I realised that my entire setup was actually different to the one out of the 318i.
You see my car has a second piece underneath the the master cylinder, like this one:
Assembly (internet example as my phone camera is horrendous):
Piece (also from internet):
The new setup I've bought doesn't come with the extra piece. I've looked the part up and there's not much information on it, some call it a "Pressure Regulator". A Link I found after googling Pressure Regulator, calls it an ABS pressure regulator, but I'm 99% sure my car has no ABS. I'm 99% sure that the car I bought the setup from also doesn't have ABS.
My thought was obviously to just replace my cylinder and booster only but not the pressure regulator. But my cylinder is actually different to the one I bought, and so the lines don't fit and I'm still not sure what the extra piece does, meaning I'm not sure whether I can just run the new setup, or if I need to make up new brake lines to fit the regulator to the new cylinder.
My cylinder (which Ireland Engineering sells as an e21 Cylinder):
New cylinder I've bought (which doesn't have the brake line to passenger side front in the same spot):
Anyway, I'm unsure how to proceed. Do I just whack the new brake cylinder on and ignore the pressure regulator, or do I make new lines up and fit the old pressure regulator (which could still be the part that leaks, I'm not sure), and go from there?
Also I'm broke, that's why I'm buying used parts rather than new, I gotta get to work.
Anyway, any help would be much appreciated, thanks a lot.
PS. My car is Right hand drive if that makes a difference.
