Xp 850 still having brake issues
Ok talked to the manager at my dealer. they called polaris to see about extending the warranty to the brakes as they are 300 miles old. No such luck "wear and tear item" . I then called 1-800 Polaris and they were no help at finding who I need to talk to. Again they said "wear and tear" . For instance to me this is like buying a brand new car and having to replace the pads after 3000 miles. That would be ridiculous. Anyone know a number I can call ? If not what do I need to do so I am not replacing pads again at mile 601? And no, riding it like a regular utility quad is not an option . I bought an XP to ride the hell out of it.

By my 2008 800 manual the adc only works below 15 mph.
adc works as a engine brake....so as I take it does not work on the caliper system.
Did you check you back pads?
I was also wondering if they use a proporition valve in that 850 machine?
You buy a machine you need to buy a polaris repair manual for r model and year as it seems there changing things every year it seems.
To my understanding ADC uses engine braking in conjunction with the brakes....
and on another fourum i'm on there is a few posts about this problem as well and it seems most just switch the pads to a better higher end pad(different material) and it seems to fix the issue....i will lookfor the posts again..

My bike is still at the dealer and I cant get it till friday. when I get it I will take a look and confirm how many pads ill need. they didnt mention the rear pads but they looked as bad as the fronts. Let me know if you come across any after market pads .. maybe a different rotor setup would work better as well?

Daledo,
You shouldn't need any aftermarket rotors/brakes. Thes OEM set up should last a long time.
If you didn't do anything to cause the issue, then there was something wrong with the rotors, brakes, calipers, or all of the above... I don't care what Polaris says... period.
If the new brakes/rotors do the same thing, and you are sure you are not doing something to create the issue... I would go back to the dealer screaming. At that point I would suspect there is something wrong with the calipers or the brake system (hydraulics) affecting the calipers.

ADC it totally independant of engine braking and the wheel brakes. ADC uses an electro-hydrualic brake of sorts that is contained in the front differential.
The whole reasoning for ADC is that the differential cannot utilize engine braking due to the over running clutch design. In other words under engine braking the front wheels are allowed to free wheel and over run the speed of the differential.
This overrunning clutch is key in the operation of the on-demand AWD,so to allow all wheel deceleration they came up with ADC.
ADC engages a "brake" in the front differential that is connected dirrectly to the front drivetrain through the ring gear assy...this coupled with the way the system activates..ie throttle released, less that 15 mph ect,simulates "engine braking".

i agree with DCT on this one. There is something that has caused this problem to arise and the dealer should stand behind the product that they have sold you. 300 miles and putting brakes on it is insane. Fix the problem and in 300 miles take it to them again and loose $200 in parts. Then they will say you prolly put them on wrong to cause it.
