I bought a used Roketa ATV-06. My first mistake was buying a used quad that someone else beat the hell out of and ripped apart. My second mistake was buying a Roketa. Buying used would not be a problem if there were resources available (Service Repair Manual). My friends (whom are Polaris mechanics) and I blindly rebuilt the engine, honed out the cylinder, and replaced the broken compound gear. The problem now is since we got it to actually run, is trying to stop it. The rear brake line was damaged (looks like the line touched the exhaust at some point). And we cannot properly get the brake line bled. With the front handgrip we got pressure which is somewhat pushing on the back brake caliper, but nothing to the front. When we try to bleed the front brakes using both the foot lever and the front brake lever we get some fluid but hardly any pressure. The front caliper will not close and there is no tension what so ever on the back brake lever. The way the system appears is that the hand grip has a 60” line that runs to the rear caliber. From the caliber it has another line running back up to the front brakes which splits to go to each wheel. What we are assuming is that when the line got damaged maybe a piece of braided steel got in the line and froze up in the rear caliber. Has anyone experienced this problem in a Roketa, or possibly another quad? I am open to suggestions. The only way to avoid all of this troubleshooting is to replace the whole brake system from Roketa’s website running me about $200. Another problem I am having isn’t as aggravating. Now that the bike is running it seems like the clutch plates may be bad. It feels like after you shift gears (4 Speed +Rev) it wants to slip and then build up torque. Is this a clutch issue or possibly something within the engine? Again, I am open to suggestions even if it’s saying to scrap it and buy something better haha. Thank you for taking the time to read this!

 

you're right, roketa cables are bad about fraying inside the jacket housing. glad you got it running. use DOT 4 brake fluid. did you use roketa's website or this other one?

I used www.roketa.com. Has the whole hyrdolic brake system for 180.

 

Jaster thank you for taking the time to research my problem. The rear caliber has two hydrolic inputs. The banjo fitting on top is from the handbrake and the banjo below runs to the front to connect to the footbrake and front two calibers. It is a brake system I have no experience with. Trying to just find a new rear caliber is starting to get annoying. Again thanks for your imput.
