This is the E Brake, the one that is on the center drive shaft rotor below the dump bed. It is NOT related to any of the wheel disc brakes.
A few months after purchasing my Coleman Outfitter 550 (Hisun) new, the E brake stopped working. Thought it had got water or oil on it as it gradually went from good holding to poor holding to literally NO holding. Been lazy using a piece of 4x4 to keep from rolling, but that's a pain. So, into the barn I went with work light to see what the heck is wrong. E brake pedal worked, but hit a hard stop and felt like the cable was froze up from rust but that was not the case. As it turns out the E brake is actuated by some kind of weird actuator lever/cam arrangement based upon the actuator lever being moved about 15 degrees from its fully released position. That makes the adjustment pretty critical with such little movement. Bolt "C" in the pic below is the adjustment bolt, held in place by lock nut "B". Working from below, here is what I did.
Removed the skid plate below the E brake. 6 bolts and washers. Next, looked at the brake pads which still had a good amount of pad left on them. Looked to be a little less than 1/8" each. Verified that the cable from the E brake pedal "A" actuated the E brake arm "D". Cable "A" pulls and released lever "D" in the direction of the curved arrow. Applied E brake and checked the actuator arm, it was all the way up with no bare cable "A" showing. Released E brake and checked the actuator arm, it was all the way down with bare cable "A" showing as in the pic below. That spring pulls the lever to fully released position. Note: I disconnected the release spring from at the lever with needle nosed pliers to make working with the adjustment easier to do without that pressure on the lever. With E brake released, loosened lock nut "B" and backed it off the lever about 1/8" or so. Tightened adjustment bolt "C" by hand just until it stopped. Retightened lock nut "B". E brake now holds securely on my hillside driveway, and releases completely. Reinstalled skid plate. Hope this might be of some help to someone as none of this is in the owner's manual or in diagrams.

Released brake and rechecked the actuator arm, it was all the way down.

I have had my E1 since late last summer and I have always noticed that the parking brake was weak or non existent. About a month or so after I purchased it I mentioned to the dealer that the parking brake did not function well. What I was expecting from the dealer, ' well bring it in and we will correct the issue.' What I got was the typical dealer response, "it may just need to be adjusted." No shit! Well I finally decided to adjust it. A very simple process need only two 10mm wrenches. Open the bed, remove the pin holding the bed to the strut and move the bad out of the way. Right in front of the electric motor is a brake disk. That is the parking brake. It has a small set of brake pads that are actuated by a lever attached to parking brake cable. There are two 10 mm nuts on the shaft to moves the pads. Release the inner nut and hold it in place while screwing in the outer nut - that is really a bolt. After screwing it in about one turn, tighten the other nut. Check the parking brake. If it is holding when activated, then you are good, but if not, then you may have to turn the bolt another turn. Do not turn to far or you will lock it up.

I'm sure many of you are aware of Michigan's emergency brake requirement. I'm wondering if anyone has a good solution.
Beyond paying the few fab places $$$$.. I'm curious is there another rear caliper with e brake style that would interchange with slight mods to the Maverick sport rear mounting bracket?

The conversion took about 350lbs. off the vehicle. It never rode great, but now I feel every crack in the road. I have backed off spring compression nut to the point just under where they would move around if suspension was at full extension, but it is still very stiff. I would like to put some softer coilover springs on it, but I have no idea what the spring rate is with the original springs so I would just be guessing on what to order. Does anyone have the data for the original spring compression rate? I am willing to give up a little ground clearance for a softer ride. Right now when sitting still the rear suspension is at or near full extension and the rear tires have several degrees of camber which will cause uneven wear if allowed to continue in this state.

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:
