Dual brake system plus 2

PostPost by: Dieschelan » Wed Oct 16, 2019 4:36 pm

Hi

I have in my plus 2 the federal brake system (my car is lhd and swiss market)
My system has dual brake máster cylinder and 2 servos.
Now I don’t have enough space for the 2 servos. So I considering to convert the car to a single brake system.
Wich parts should I need?

Regards

Dual Circuit brakes is a safety feature and not one I'd be looking at removing. (Actually one I want to add.)

Potential other options:
1) Smaller dual circuit booster - https://www.carbuilder.com/uk/compact-d ... rake-servo
2) Mount one booster in the nose (as suggested by rdssi)
3) Go to none assisted. A Spitfire small diameter dual master should fit a LHD +2

Note sure what the Swiss would make of you going to single circuit, my assumption is they quite strict and it may cause you issues.

Thanks for the answers.
In Spain and rest of Europe the original setup was single system.
I was also thinking in putting a servo in the front, but can this affect the air flow to the radiator?
If I convert it to single system should I need only the servo and a new master cylinder?

You probably won't need a new master cylinder.....just a remote servo ( 3.0:1 ) placed wherever you want...
