Technical Fiat 850t 1977 brakes

[Perojo]

I'm looking for someone who might have experienced this. I have a problem with my brakes. It's a 1977 Fiat 850t.

I had no pressure left, so I ordered a new master cylinder. It was the same one in the photo, but unfortunately, the upper cylinder is different from mine.

I've had it adjusted, but I can't get it right. Who can help me?

A bit more detail would help.

A 1977 should have a tandem master cyinder I suspect. What is the main problem .... can you not get the air out of the system or is the pedal low? As mentioned .... more detail would help.

Please include photos.
The 850T / 900T / 900E master cylinders are slightly different. I only found out when I ordered a replacement for my 1978 900T and it appears to have the later 900E version fitted - so I had to swap it for the later version. On the plus side, if I ever get around to a disc brake conversion the (bigger) master cylinder should be up to the job.

Are you talking about the piston sizes or the reservoir size as both releavant especially for a disc conversion.
