have being bleeding chinese quad rear disc brake but jst dosnt seem to do anything...is there anything else i could do to get brakes to work??


also starter button wont work on handle bars quad starts up no problem when jump the relay/seliond..dont have a tail light to test it that way .... any help appreciated thanks

 

Read my post about this. I had the same problem with the solenoid issue it ended up being the remote box. I replaced the key starter/kill/light switch and solenoid. You need to get a test light and start at the ignition testing wires

 

On the brakes you may want to unbolt the caliper. raise it above the master cylinder while bleeding. We also take the line to help any air rise up to the caliper. It is a trick we use when normal bleeding and vacuum bleeding doesn't work.

 

...or you can get a large syringe and push fluid from the caliper to the master. This is how I do them. The plunger is so small on these that if there is even a little bit of air in the lines, the plunger won't do anything.

 

thanks guys got it sorted thanks !

 

I would say it's best to end your thread with what you did to resolve your issue. This helps others in the future.

 

I fixed problem by trying both methods above I first tried the syringe as was quicker method it did help but I still found it wasn't clamping on brake dic as good as it did so tryed second method by unbolting that caliper and rising it up over the master cylinder and bleed it while it was rising up now working grate thenks for help !

 

Awesome. I always found that sometimes a combo of a few things seems to work too. When I syringe bled my front calipers, it got most of the air out. Once, most of the air was out, I could use the traditional method of bleeding by pumping on the brake handle (master cylinder). The issues are the ATV's have very small master cylinders, so there really isn't enough pressure to push the air out. Unlike in a car, there is a lot of volume pressure to pump the air out by pumping the pedal.

 

I use a brake bleeder I got from Harbor Freight for about $20 on sale... use it for all my dirt bikes/quads and my cars and trucks..

 

Is this the vacuum bleeder one? If so, I found this to be a hit n miss. When it does work, it works great. I found that some systems don't like the sucking, I think some systems have diaphragms that don't allow this. So far, pushing fluid has always worked for me. As long as the lines are clear.
