Hi Klumzer

I think you will find that the red wire you can see travels up behind the master cylinder and that the extra outlet is blanked off. If my memory serves me well in the Alpine/Horizon cars the two front callipers had separate pipes running from the front of the master cylinder with a single pipe running to the rear brakes.

Regards

Ah you mean brake proportinal valve mounted right in the rear.
I never tried but this should be a solution.

It is adjustable and you put it in the rear brakeline.
The original valve you can replace by a T-piece.
If you mount it in the car you can adjust brake balance in the car wich could be nice in bad weather.

Yes, I meant that one. I tried to translate the Hungarian expression... Cheesy
First we try to save the old valve, but it is in bad shape. So if it fails now there are two other options. Thanks.

Yes. Try to get a used valve in better condition.
