I OWN 2 POLARIS SPORTSMAN A 500 EFI AND A 600 TWIN BOTH WITH EBS. BOTH UNITS WHEN I SLOWLY ASCEND DOWN A STEP HILL THE FRONT AXLE SEAMS TO DISENGAGE ONLY ALLOWING THE REAR TO BRAKE AND MOST OF THE TIME IT IS SLIDING CAUSING A NEAR OUT OF CONTROL SITUATION. IS THIS THE WAY THE UNITS ARE DESIGNED OR DO I HAVE A PROBLEM WITH BOTH UNIT

 

This one thing I HATE about Polaris they desined with only rear wheel engine brakeing thoe the new ones (07- newer) have adc controll which gives you four wheel engine brakeing thoe I have never rode one and cannot attest to how good it works!

So to answer your question like it or not yes your machines are working normally!

 

I have'nt as yet gone down a hill steep enough to require the use of the brakes at all! And yes, I've gone down some pretty steep ones! (09 850 XP)
With the ADC switch ON It just creeps down the hill like theres nothing to It.
Here's a quote from the sales brochere about the system, "Active Desent Control (ADC) and Engine Braking System (EBS) work together to electronically monitor and control four-wheel engine braking to give you optimum control and smooth, even deceleration during descents."
It works just like they say it will. As far as I'm concerned It could'nt work any better!

yes that is the way thier designed. the ebs is only for the rear tires unless you have a07' or newer one w/ adc

 

If this helps, it does help me, burp the throttle going down descents to engage the clutch and continue in and out of throttle to keep rear wheels from skidding.

 

Working the trottle like outback said is probably the best way to deal with it,other than using the brakes. Some like burping thr throttle and others say it works well to just give it enough to engage the clutch and maintain that but I would think that would get you going pretty good. Either way it will take some practice.

Dodge57hemi-The ADC works very well,makes the machine easy to control even on pretty steep desents. You can start out on a hill with it off then click over to ADC and feel it slow the machine to a creep. But I only turn it on when I need it as the more you use it when not needed the faster the components will wear IMO. I could see some getting in the habit of pushing the switch all the way over to ADC when they just need 4x4 as it's easy to do. Hill or no hill if the right prerequisites(throttle at idle,less than 15mph and ADC switched on) are met it engages.

Thanks for the info. Thoe my Popo is on rear wheel engine braking only it does work good in most situations sometimes to good I hate having to blurp the throttle on small downhill runs!

 

What kind of tires are y'all running? Reason I ask is with stock tires my 850 would slide the tires on slick hills covered with wet leaves with the ADC off,ie same rear wheel engine braking. I switched to mudlite XTRs and it hasn't slid yet. More traction should overcome the EBS and help it not slid. Just a suggestion.

 

I still have the stock Good Year Rawhides! Thanks for the help!

 

Yes it is hard top believe that is the way it is suppose to "work" but it is. First time I rode a Polaris with EBS I thought it was broken. It started skittering, sliding and the back was trying to swap ends with the front. It was a friend's brand new machine and I thought I'd broke the thing a few hours after he got it. Not only that but I almost wrecked the thing coming down a graveled hill because of the stupid EBS.

I took it back to the house and I told him I thought I'd broken it and that I was very sorry and would pay for any repairs. I told him what happened and he explained that it was supposed to act like that. I was shocked.

If I had a quad with EBS I'd try to have it removed. I swore I'd never buy a new Polaris until they got rid of that horrible system. They finally added ADC which is as good as the EBS was bad. ADC rocks. Probably the one of the best engine braking system there is. Just as good as Can-Am maybe a little better. A night and day difference from EBS.
