I have a 69 Type 3 Squareback and replacing the Brake Master Cylinder. The old one is a THREE circuit two prong and all replacements are two circuit. What are the three circuits for and can I replace it with a two circuit?

I have not found a three circuit replacement. What are the three circuits for and can I replace with a two circuit? |

Yes. In fact VW replaced it with the 71 and later style dual circuit version themselves. They obsoleted the 3 chamber set up at the same time (why you can't find one). You'll need to switch the brake light switches to the 3 wire units, and alter the wiring as shown in the brown Bentley to keep the dash warning light function. If you're not worried about it, you can use your 2 wire switches. Keep in mind you might have to replace your left front hard line depending on the port configuration of your new master cylinder, with a longer line. Most of us have already done this.
I hope this helps. _________________ Bob 65 Notch S with Sunroof
