Master cylinder question

Can I fit a master cylinder with just 4 outlets to my mk1 GTI ? I was going to put the brake light switch on the pedal instead.
Thanks

Yes you can, later cars and cabriolets used a brake pedal switch.  

Nice one thanks!

The Cabriolets also had the proportional valves for the rear brake shoes/wheel cylinders on the MC on opposite corners.

What do those look like please? Where are they on an 83 gti please?

83 gti they could be on the fender passenger side or next to the rear axle as they are possibly weight controlled.

I have a 93 Cabriolet they are on the MC.

Mine has a valve near the rear beam where the rear brake pipes go into, then out to each wheel. Is this it?

Picture?

Just to be 100% sure before giving advice as it is part of important equipment needed on a car…  

Still not sorted this but getting closer. There are 2 sizes of master cylinder for the cabriolet according to VW heritage, 22.2mm or 20.6mm. Any ideas on which will fit my servo and brake system please?

these are the valves fitted to the master cylinder as per later cabbie set up . 22mm m/c are for the larger servo upgrade
