Didn't see whare anyone answered the question about pulling while braking....the reason it doesn't pull is the rear is a locked differential...so when one wheel is slowed so is the other...

Hope this helps..

Yep, didn't think of that... makes sense.

 

it doesn't pull because the rear end is solid ,both wheels pull at the same time and stop at the same time. power is less on the 550 so you don't need as much stopping power.

Here is a comparo between the 850 and the 550 not much diff than the obvious! [IMG][/IMG]

Never noticed that there is nearly 50 lbs difference between the two machines. Most of that must be in the block. Hmmmm... maybe there's room in that 850 block for a 950. LOL

 

Actually almost all ATVs have a single disk or drum brake on the rear axle, ( some have a sealed internal wet disk), this is more then sufficient on most bikes since the brake bias runs something like 70%/30% front/rear.

 

I wish Polaris would go two a two brake lever system like the Grizzly's (4 wheel disk front and rear 550 and 700 both)have esp on the 850 it would make it allot more sporty to ride and IMO give you more controll of the bike!

That wouldn't be too hard of a mod really...all you would need would be a R/H lever/master cylinder,a hose,a junction block, and 4 plugs..
You could use polaris OEM parts for the block and hose if you wanted to...
Mount the master cylinder/lever assy. The junction block is up front below the rack,mount the 2nd block run the hose from the master down to the block,hook the brake lines to the block,plug the open ports on both blocks..bleed and you are done...you choose which side you want to control what brakes..
The hardest part might be finding a lever assy that will not hit the ETC when you pull it hard..

Edit-Actually you wouldn't need the block,just a ftting to connect the hose from the lever to the hose to the rear brakes..it's a single hose...but that way would make the rear foot brake inop...if you want the pedal to work you would need to also hookit up to whatever junction block you have the rear brakes working off of..
It you wanted,but with the 2 lever ssytem no need for the pedal unless you wanted triple redundancy in case both main mastercylinders went out at the same time,lol..

Not on the back, if one wheel locks so does the other unless something is broke ,there is no simited slip on the back end unless it has truff mode.

99% of ATVs only use a one wheel brake system on the rear.

 

The 800 Touring has 2 rear disks and that along with the extra fuel capacity and turf mode was how the salesman kindly helped to sell me on it.
