What are the possibilities of adding a right-side brake lever to control a second braking system on the rear axle of a Scrambler? (rotor/caliper/etc) Could this be done? Just splitting the brakes does not seem to be "enough" but to add a second rotor and a whole other set of pads somewhere on the rear axle...

It's crazy...maybe even silly...but is it impossible?

 

It can be done, but for the price of a yamaha complete bike
Why don't you just get an anchor? drop it when you want to stop!!

No kidding, it will probably be cheaper (and less maintenance) to put a big disc and new caliper (get a 320mm disc with 6 piston caliper...don't get too powerful on the rear...and check your front/rear splittage...sounds to me too much rear brake. Anyway, it's possible but maintenance is gonna get real "invading". Get a single giant disc and works caliper. That will brake.

 

RCR makes a kit to split the brakes, but polaris rear brakes are junk I would'nt waste the time and effort to do the work.

I know that the brakes are junk...just spent over 75$(can.) for rear pads which are shot after two days... Tomorrow I call Boxbrakes. I just want it to stop good and last longer between changing pads. What about Zorro's idea of getting an oversized rotor?

I don't know of any company that makes oversized rotors for polaris, but if I come across one I'll e-mail ya the site, now you got me scratching my head.

Go to www.brakingusa.com
Check their wave disc...that is cool (should be expensive...and I don't think they make one for the scram...anyway, that's the kind of rotor you need).
They're the best disc brake makers (or most popular aftermarket discs). I know they have discs for about any MX bike, I don't know about quads.

Without being that extreme, get a serious disc...have you looked at the size of your rotor?? It's crazy how small it is!! Shame on Polaris (finally I can blame polaris for something, and for real). The scram is 200lbs heavier and the disc is half the size of my shee...no wonder pads can't handle it.

I don`t think it should be too difficult to get one for a Polaris the only thing different is the bolt pattern. Personally I `m not to crazy about the loss of ground clearence. Adding another disc would be possible. You could make a spacer/adapter that bolts to the sprocket (like the guard) then make a mount for the caliper add some lines and your done LOL. I have thought about putting a nice big 4 piston caliper from a bike in place of the stocker it would be more stopping power. I wonder how much more longevity the pads would have however. I have heard and I tend to believe the holes in the rear rotor are what excellerate the wear. If you get a different one consider a solid one. HTH

Why would holes wear the pads??? They don't. Their utility is to clean up from sand, dirt... (which wears the pads). Their other role is to keep the disc cool, so they don't melt the pads. Take a look at the KTM (bikes) catalog (don't know the URL). Look at their discs...think it would wear the pads?? no.
Look at www.brakingusa.com , thet know what they do, look at their discs...

I agree the holes aid in cooling but they also hold the mud and allow it to get between the pad and the rotor causing increased wear. Also once the mud is in there it gets baked in and closes the holes anyway. The front rotors do not have holes and last twice as long even though more brake pressure is applied to them.

I know there is a lot of holes in motorcycle rotors and they work fine but why doesn`t Yamaha put holes in the rear rotor of your Banshee or the Raptor I think they would benefit more from holes than a Scrambler.

Then tell me why my rear disc (full) looks like a plate (completely bent), and since I changed it to an EBC (whith holes), there's no noticeable wear on the pads, and NOT ONE SINGLE PERSON has adviced me to put back on the original one.
Please, I know what I'm talking about.
The cause of the pad wear is more probably the poor design of the polaris rear brake...
After all, believe want you want.
