OK guys... this one's a little tough, but I think someone might have an answer. I've got a 2000 Trail Boss, and the brakes are horrible! The pads are fine, but the whole system is way too small. Any of you with a TB will agree if you look at the rear brake assebly. The sproket is the same size!. I want more stopping power, and was wondering if anyone knows of a company that will sell bigger brakes for Polaris models, and how much they are. Or should I just get different pads? I believe small brakes are a problem on all Polaris models however. My Magnum's brakes are small too, but with EBS, I only use them for stopping short and on tight trails. Any help with this would definately be apriciated. Thanks!

 

You can't judge the Polaris braking power by the physical size of the brake rotor or caliper.

There is absolutely no relationship between the braking power and the sprocket size. The brake rotor is mounted on a shaft within the gearbox that has excellent mechanical advantage. It is not the same shaft as the sprocket is mounted on, so there is absolutely no relationship between the size of the brake disc and the size of the sprocket.

Brakes on equipment are often mounted on a mid shaft within the gearbox, a shaft that has good mechanical advantage. This allows for physically smaller brake rotors and calipers that will still provide excellent braking power. Case in point is my John Deere garden tractor. It has a brake rotor that can't be more than 2 inches in diameter. The Deere will easily lock the wheels with little pedal effort.

The rear brakes on my Sportsman look small, but given their positioning in the drive train they have incredible power. All 3 wheels will easily lock if desired.

This is the first time I have heard someone say the Polaris brakes have inadequate stopping power. I have always found them excellent. My Honda Four Trax on the other hand ...

Deej the rear brakes on a trailboss are on the back axel not on the gear box like a sportsman. I have a 2000 trailboss and the brakes are tough to squeeze.Upon close inspection I noticed the rotors were painted after a 100 miles ore so it stopped much better. How much time do you have on the machine Pineykojack? Once the rotors cleaned up it stopped much better.

 

Heres what I heard: I went to my dealer last week, brakes shot again after 50 miles... He just returned from a Polaris training session and told me that the instructor said that there should be a recall on this years models to replace the braking system. It is only hearsay so do not count on it yet.

 

My second pair of y2kboss rear brakes are gone after 80 miles. The rotor is really grooved and chewed up also. My dealer suggested I bring it in to make sure the calipers are ok.

Can you get the rotor turned or do you need new ones. How hard is it to change ?

 

sixty9,

Im not totally sure about how much time I have on the machine because I have no odometer or hourmeter. I'm pretty sure it's close to 60 miles and about 10 hours going by the numbers on my Magnum. We usually run them at the same time for about the same time on trail rides.

 

Xplor,


What models would the brake recall be on?

 

The dealer told me on all 2000 models. But then again we hear a lot of speculation out there! He said that the technician from Polaris said that they finally realized that the braking system was not up to par. My own dealer has had about 50% coming back with used brakes. He even had the nerve to tell me that if your riding technique involves a lot of braking it is normal for brakes to wear out fast. What a crock! He told me to try and not use the brakes so agressively. I own a Scrambler400 with a few mods...brakes are esential!!
