Joyner t2 break problem

First the trooper has 2 master cylinder.1 cylinder dose L/F  R/r the other 1 dose the other 2. We have a pressure bleeder.Some times we use to fill the brake line at the master cylinder till it comes out the bleeder of the caliper bleeder.Close the bleeder and attach the brake line to master cylinder.Then bleed at master cylinder.You may have a clog in the brake line blow it out.Be careful blowing out line.Cover the ends of the lines.If this doesn't work call me on Monday. 928 246 6819

Here's something to look at, this happened to me on a 2014 R2 I bought used. I had weak a spongy brakes so I tried to bleed them and kept getting air out the system. I had a vacuum pump and even went and bought a pneumatic brake bleeder, still was getting air bubbles. So I pulled off the master cylinder. While doing this I noticed that the rod from the brake pedal to the master cylinder was at a down angle. I then took the master cylinder apart and found scoring on bottom of the piston and the cylinder bore. I replaced the master cylinder and changed the rod position and it now works fine.

I tryed everything and I still couldn't get any pressure... so here's what I did.. I bought break lines for a chevy truck.. there are a 10 mm banjo fitting just like the Joyner but on other end they are a 3/16 standered break line..  i also bought a 25ft roll of 3/16 break like and made my own lines and bought a master cylinder for a very dune buggy..I have great break now...!!!

      My "R" light on the dash will not go out when I take the UTV out of reverse and put it into any other gear. Is this just the light switch issue or will this effect engine performance in the other gears?

      In the market for side by side. Narrowed it down between the pioneer 1000 or defender Hd9. Looking for pros and cons of both. Any info would be helpful in my selection process. Noise, speed, reliability, ride, all of it.

      Hello, All!  I've decided to replace the traction batteries in my 2018 Sector E1 with a 48V Lithium set. They may be expensive, but I figure the Discovery Dry Cell are, too. I am not looking for the max driving range, as I have never received near the brochured range to begin with, but a good mix of charge/ get work done/ charge is what I am expecting.
      I have settled on the 48V EAGL kit from bigbattery dot com. Each battery pack provides 30Ah. The kit ships with a charger, as well. The packs would be physically connected in parallel (using a busbar) to one another, maintaining the 48V voltage, but together would be able to provide the amp draw the buggy pulls when going up hill or towing a rake (rated 320 max continuous Amps). This is in comparison to the serial connection the eight 6V lead batteries. Each of the EAGL batteries looks to have its own BMS; am I correct in thinking I will have to use their included charger rather than (simply) changing the onboard charger to lithium mode? The chemistry of the pack is LiFe PO4, for what it's worth.  I haven't torn anything apart yet (to diagram), so  I am not sure how the dash will interpret the AMP draw, but the kit I am looking at includes a dash mounted charge indicator.
      If anyone has completed a similar conversion, do you have any tips? Specifically, how did you remove the original batteries, and how did you secure the new ones? I am guessing that almost any change from the stock batteries would involve at least some modifications. Any tips would be appreciated, especially things I may have failed to consider. Thanks!
