Hey guys please did a 100 miles on my trooper this weekend I noticed that sometimes I hit the brake the pedal seemed low or soft and I noticed that sometimes after braking a little hard the next time I hit the brakes the pedal was hard. No leaks still got meat on the pads I'm assuming maybe internal master cylinder leak any ideas has anyone replaced a master cylinder and with one

I do have a little play in my front bearing but I have talked to Casey at jmc a few times about it and he feels like I am Probally with in spec. When I take the wheels off and grab the rotor the play is minumil and no grinding or noise from the bearings I have tried to get the bearing tighter nothing has worked and they r tappered bearing last time I replaced one there wasn't much difference

Charlie...your brakes should be 1 master supplys 1 front,and the opposite side rear brake..the other the opposite front/rear combination...kinda like an X ..makes them fun to bleed,normally have to remove 1 of the "push rods",bleed,then switch sides. A common problem is when the master cylinder piston does not return all the way back (up against the circlip) sometimes just cleaning out the "gunk" in the end of the master will allow it to return...bigdan,have done a number of heaters,where did you plumb in and out ? what are you using for a heater ?

sounds like you already know the problem...the input to the heater is the "almost" 5/8 line,not exactly sure where you returned,but sounds right...that circuit kinda bypasses the rad and themostat...the air lock can be a bit#% to get rid of...can you get your core lower (below head /rad upper hose) at least to bleed out air?...even loosen clamp(s) at heater core while running (carefully) to allow air to escape?...just my 3cents...Hardy

Charlie,its awkward...but if you look where the brake "push rod" goes into the master cylinder,you can see the end of the piston...when the brake pedal is released,the piston should come all the way towards you untill it stops right against the snap ring if it doesnt come all the way back it wont allow fluid into your master from the resevior ...sometimes all it takes is to blow the dirt etc out from the end and work back and forth a little to get piston to come all the way back...just my 3cents...Hardy

      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.

      I have a 2020 axis 500 and I have replaced the TPS twice and the whole throttle body assembly once and still have code 122. I can barely drive the thing. It bucks and surges like crazy

      We recently purchased the Axis x550. Fueled it with 93 fuel and drove one time around the farm and the 02 fault error appeared. Any ideas?

      so i just picked up a 2008 1100 trooper and iv ordered a few parts for it now and 99% of what i got fits perfect my issue now is my rear wheel hub is stripped out got a new cv and it fits great but i order 2 different hubs from 2 different places now and they are both wrong the spline opening is to small to fit the factory cv shaft and yes the shaft factory part #s are the same paid 250 for an original new replacement if anyone has anything that works to replace the original hub please point me in the right direction

      Hello all. I purchased a brand new Massimo Buck 250 EFI in June for our farm and I've had the parking brake fail on me twice. I have approximately 250 miles on the vehicle. The first time was less than a month after receiving the UTV. We all of a sudden lost brake pressure and it would not start. I tracked the issue back to the parking brake. Upon removing the chain cover, I noticed the brake pad was missing and the caliper piston was touching the rotor. I found a set of brake pads online and replaced them myself. It's worked for several months and just happened again. Seems like a design flaw. I'm reaching out to see if there's an upgrade option available, or if I should replace the entire caliper with the brake pads? Thanks in advance for any advise.
      I submitted a warranty claim, so I'll keep this updated with what Massimo replies.
      When I replaced the brake pads the first time, back in July, my Son made a video on YouTube to show the unique caliper design. Here's a link if you wanted to check it out:
