Parking brake stuck


Recommended Posts

Need more details.  Tranny to Neutral.  Raise both rear wheels on jack stands.  Park brake  disc is on diff drive shaft.  Have assistant rotate any side rear wheel...open diff....opposite rear wheel will turn in reverse direction.  If TRUE, diff is ok.  Try to rotate drive shaft, if park brake locked.....NO GO.  Have seen master cyl hold pressure to FR and RR locking them up....thus the jackstand test.

Lever has stepped rack, button release....problem with release?

Cable stuck in sheath?

Mechanical brake cam/lever stuck on full pad pressure.  Need answers to go forward.

Thanks Ben 98. Took off plate and tried turning the rotor but brake too tight. I then pulled the cotter pin from the cable adjustment end and got the pb pedal to release. This freed up the pb back at the rotor and I can run it without using the parking brake. I think I just need to adjust the cable, but I’ m not sure which way to go with the adjustment nuts. At least I can ride it if I don’t have to park on a hill. Thanks Ben

The cable "pulls" the lever and thus cams the pads together in the calipers.

Reassy with slack in the cable and then adjust (tighter) to no drag at RELEASE and but make sure it will hold on a hill when set before end of pedal travel.

After thought...woods riding can snag a cabe and pull the brake tight.

Ben, thanks again.    Question:  Is there an electrical connection to the pb other than the obvious one with the cable leading to the regular brake?  The pb is supposed to release with the ignition on and stepping on the regular brake.  There are two cables  leading to the regular brake pedal. I am assuming that the cable on the left is the adjustment for the pb. The one one the right is adjustable too, and Am I right in assuming that it leads to an electrical relay, maybe for both the pb release and the brake light switch, or is it just for the brake lights?

      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?

      Hey guys! Newbie here. I'm an old man who's better with plowing a mule (4-legged kind) than these newfangled beasts. I, and a friend of mine, just bought new Coleman sxs and are having to finish the assembly. I've been reading on this site and I'm falling on the mercy of you experts. The only way I'm an expert is that an "ex" is a has been, and a spurt is a drip under pressure. LOL First off, the 2 buggies have no ignition switches. They seem to mount on the dash, not the opening in the steering wheel shaft cover, so we ordered new ones that are supposed to fit. They are 8 inches long, and have a 4-wired white plugin which is slightly rectangled when looking at the end of the plug. The trouble is there's nothing to plug into. There is a three-wire grey plug close enough to reach the four-wire plug, but of course, they are not compatible. 
      Secondly, the blinker, light, ect. unit on steering wheel just spins around when touched. I see no way in heaven or earth to secure it. I've looked at a diagram on the Powersports site, but can't detect how it mounted. Fellows I'd be so grateful for any help with this. Me and my mule will even plow your garden for free, for your help. LOL
