Bike powered smart brake set up ?

[JRM Rossi]

Now im ripping to bits a zx12r smart car due to BAD engineering. (not mine) whats the best brake set up for road/track use ? At the moment its on standard smart set up , do i go for bias set up or find a way of getting servo to work with better discs,cailpers ect it needs an mot next year but i want to do it right 1st time

Why would you need a servo for a car of that weight? Why not just keep it simple (and effective) with a balance bar off the pedal, 2 master cylinders and some decent disks/calpers? Maybe even the standard disks are OK? Certainly if the car already has disks on the back I'd be inclined to keep them as the rears really don't do that much work and it'll save faffing about trying to rig up a handbrake (for the MOT) if you move to plain calipers.

I was more worried with mot regs ? It has drum on the rear which i think is ok as i dont want overbraking rear brakes,was thinking of drilled & vented discs with good pads up front & mabe a bigger caliper just with new regulations with mot,s was more worried with servo removal....i have all the race pedal box & the smarts is still intact just no vacuum

Can't help with new MOT regs, but there are a lot of cars out there passing MOTs (mine for example) that don't have servos on the brakes. Pretty sure none of the 'Seven' style cars were ever specced to have a servo. Only thing might be if the relative sizes of the master cylinders to calipers were specced to give decent feel with a servo you might have to put in smaller diameter master cylinders to get the right feel back without a servo.

I'm stopping 1000Kg of [fairly rapid] motor without crazy pedal presure on AP 4-pots up front with no servo.
