So, I am now focussing my attention on putting the new brakes on the deuce. I just got a quote to get some new radials on the beast, and now I'm looking for ideas for the brakes.

I have the option to do one of to things:

1. Pull out the stock brakes ENTIRELY and just run completely air-driven brakes, including a new pedal and totally new lines to Front and rear circuits.

Pros -
· already balanced, airflow is known etc.
· very easy "engineering"
· pedal will likely be butter smooth to work

Cons -
· NO brakes when air system is depressurized
· lose air to the trailer connection (not a big deal for me)
· have to install many more air lines and retrofit old air connections where stock master currently is


2. Use only ONE of my new air packs, and drive it off of the stock master cylinder, splitting the air output of the stock MC to drive both the original air pack, as well as to the new air pack. The new air pack would drive the rear circuit, and the existing would probably be repurposed to the front only.

Pros
· Keep the unassisted brakes when air is low, even if only one circuit (this is why I'm thinking of keeping the stock master, with the failsafe, on the front brakes)
· Keep trailer brakes
· Keep stock pedal

Cons
· Tougher to "engineer"
· Who knows how this will work, unknown how the balance will pan out, if the air will be apportioned correctly by the stock master cylinder to drive 2 air backs.
·

Each system has its benefits. Has anyone done a retrofit like this before? I'm really torn on what's going to be easier and ultimately most advantageous. I'm leaning towards simply throwing another air pack on for the rear brakes, and just running the stock up to the front.

My goal is basically two fold:
· to split up the singlehydraulic circuit into two, for some redundancy and safety
-and-
· to increase braking power by pushing more fluid

Thoughts? Yeah, I know I'm trying to teach another polar bear to tapdance.

Cheers
Bob
