Currently, my Mk2 is running G40 brakes with a Lockheed remote servo. I understand the Lockheed servo is designed for cars with a single circuit braking system; the Polo is a dual circuit. I noticed that the person that fitted it has joined the pipes (via a T-piece) for the front brakes from the master cylinder to a single pipe which connects to the servo. Once the brake line leaves the servo, these are then T-pieced back out to each of the front brakes. If my understanding is correct, I think this renders the dual circuit braking setup useless in the event that part of the system fails. If this is the case, I'd like to remove the remote servo altogether.
I have a few questions:
First of all I'd like to check, can anyone confirm, is my understanding correct? Does the current setup remove the redundancy in the braking setup?
Secondly, I have the parts required to upgrade the brakes to a 256mm setup. How are people's experiences with Mk2's with 256mm brakes and no servo assistance? Is it decent enough? What's the braking effort like compared to a modern car?
Finally, the pipes from the master cylinder that have been joined are the one from the bottom, front and the one from the offside. If I return to a servo-less setup and want to feed those lines directly to each front wheel, does it matter which one serves which wheel? If it does matter, does anyone know which one goes where?
Many thanks in advance
