Putting my 1969 US spec 1750 Spider back together after it was "restored" by a competent but greedy shop 18 years ago. When I realized they were soaking me, I brought it home and parked it for another day - or as it turns out, a decade or two - to be put back together by me. I now am at the get the clutch to work
stage and it has been driving me nuts. I took the old brake master cylinder (MC) to be restored and they said it had been defectively done previously, so I ordered a new one from Alfaholics and had new proper pipes made up as well. But of course, there was no record of how it was taken off by the shop, so I'm operating blind.
there is a drawing of how the MC is supposed to be piped, with the pipe coming from the brake hydraulic reservoir on the top.
In my Alfa Recambi parts book, it shows the opposite with the reservoir pipe going into the bottom (2) of the MC.
Neither way has worked for me, but before we get to diagnostics, which is the correct way to plumb? I attach a photo of my MC with both positions numbered.
I tried both ways, and it looks like the Alfa Ricambi way is more likely with the bottom (2) coming from the reservoir and the top (1) going to the slave.
I filled the reservoir and it empties OK with gravity, so fluid seems to be getting to the MC
The MC is new, I presume it will work once I know what to do.
- Disconnecting and lowering the pipe to the MC produces fizz but very little fluid.
- Loosening the #1 position (to slave) does the same sort of fizz, but very little fluid.
Do I need to pump dozens of times or what?
I've never run into this before and would appreciate instructions for dummies.
I am flying to the US next week, so if I should be buying something (such as a hydraulic hand pump or something), I would appreciate the advice on that as well.
