Need Mech Brake Advice and pinion/ motor shaft help...

[Jahay]

sorry guys, i didnt make it clear...

I wanted to run dual discs front and single disc on the rear :)

What you are looking at in the pics are my front brakes...
BUT

as the motor is in the way, and i need a spacer to pull the motor from the mount so the brake assembly has space.
So it looks like i can only have one brake disc on the front, unless i use the tekno long shank pinion (but i do not like the idea of only being able to use a single type of pinion) ....
i can still have two on the rear, but as we all know all the braking is basically done with the front... so only one will be necessary....

So as i can only really have a single disc on the front, im wondering what are the best discs and pads that will work for my applications???
