I am in charge of Georgia Tech's Mini Baja Team's suspension this year and I need to find some good brakes for the car. I have done a lot of research both from books and the field about suspensions, but I do not know much about brakes. What brakes would you recomend for a mini-baja car. Price is of little importance, and the spindles will probably be designed by me, so I can make any calipers fit. The car weighs around 300-350 lbs without the driver and we will most likely run 22" tall tires. We plan on using a single brake in the back, and one for each front wheel with dual master cylinders. If you need any more information, let me know and I will get it to you ASAP. Thanks for you help!

 

The best brakes would be the R1/R6/FZ1/etc brakes.
They're 4 piston, an dif they can brake a 400lbs bike (+ rider) from 160mph...they should brake your 10hp buggy. They can handle 1800kJ of energy, so you would be on the safe side...hehe. You can try to find smaller "rotored" brakes, so you don't have to bother if the caliper will take a smaller rotor or not.
The only thing you have to look for if what rotor size goes along. For this, you will have to call the caliper manufacturer so they can tell you the maximum and minimum rotor sizes. MAYBE they're written on the caliper itself, but I'm not positive about this.
If you want to keep a certain balance between front and rear, you might need to change mastercylinders (bigger=less pedal travel and more force needed, and smaller piston=less force, but more travel). You might want to use stainless steel braided lines, and "drilled" rotors (or even, if you can afford/fit, wave rotors like found on KTMs or sold by Braking, they kick mud out very efficiently).
I DO NOT recomend ATV brakes...except maybe the 650 prarie rear one. They usually $uck...no wonder TT pros put 2 calipers up front...

Any brake questions, go ahead, I'll try to answer.
