You should have the "upgraded" brakes on the 2009. Early 2008's had smaller rotors. The brakes still stink though. I upgraded my front calipers with brembo dual pistons with some improvement. Lenny has had the most success. He added an extra caliper in front. My next step will be to go to smaller master cylinders and try that. We have a automotive size master cylinders pushing ATV size brakes (too much volme, not enough pressure).

Rocmoc was going to switch his brake lines around so they are not criss-crossing, but I haven't heard if he has done that yet or the results.

I have my brakelines switched, 2 fronts on one master and 2 rear on the other. works good. I guess with the stock setup that if you were in 4x4 full lock out and one master cylinder went bad, you would still have brakes on all 4 wheels and you wouldn't be in 4x4 full lock unless you were trying to climb steep (or in mud) so this would make some sense. Switching the brakes would eliminate this marginal advantage plus 2 brakes won't stop it anyway. I have my parking brake on the driveshaft so I do have all 4 wheels braking if I'm in 4x4. Even if both of my masters go out, I still have good braking. Two calipers on each wheel is fairly easy and gives a lot better braking.

See the "Joyner Trooper dragging brakes" post for pictures of my brake setup.

      2014 Intimidator Brakes
      By Mike McDonald
      I have a 2014 Intimidator and need brake pads and calipers. The price for pads and rotors are outrageous through the dealer. I have heard Intimidator used the brake assembly from a compact car when first building these UTVs. 
      • Can anyone tell me of a less expensive source to buy brakes for Intimidators from,  or
      • Can anyone furnish information on what make and model vehicle Intimidator  used their brakes from?
      Thanks so much for any support you can provide me on this topic.

      Joyner trooper Fuel injection
      By Nutcase
      I have a Joyner Trooper 1100 4 place that has been sitting for a number of years. I have everything taken care of but i can't get the fuel through the injectors. Fuel pump puts full pressure on them but they don't turn on or spray fuel. Any ideas?

      Brakes
      By Greg Kilgore
      This started back in the summer. 
      While on a ride with the wife. Applied the foot brake and the pedal went to the floor. Thought the brake pads were gone. Ordered new pads. Removed the wheels to install new pads and they were in good shape.
      So I bled all 4 brakes cylinders. Got thin dirty fluid out. Almost like dirty water. No air. Got a good pedal.
      Then about a month later, same thing, brake pedal back on the floor. Could pump the pedal and get a little pedal back. Bled again and finally got a good pedal. The fluid was nasty like before. No air. And the fluid was topped off in the reservoir before I started the bleeding process.
      Now same thing. Pedal going back to the floor. Reservoir still full. I'm thinking the master cylinder is bypassing. So have a new on on the way and will report back.
      What do you guys think. Could it be something else.
      I used one of those hand operated vacuum pumps to pull the fluid out of the reservoir when I was bleeding before. First time I've used one. And after a small amount of fluid filled the catch bottle. Seemed like the vacuum pump quit working. Had to close the bleed screw. Pump the brake one time. The start the vacuum thing again.
      Again just wondering what you guys think. Using DOT 3 and DOT 4 brake fluid. Whatever I can get at a reasonable price at parts store.
