So I finally got my 200cc Jetmoto atv runnign good and ready to test. I got on started it right up and went, then I tried to stop. The front brakes work prefect, but the back ones don't really grab that much at all. When I cranked on them I was expecting the back wheels to lock up and stop me instantly on the cement, they didn't! It was like almost as if I was doing nothing. I lifted the atv on the rack and tested it by pressing on the brake lever with my hand and I cannot spin the tires. The brakes grab. As soon as I put the bike down on the floor and hit the brakes with my foot, I can still push the bike around with not much resistance. Am I missing something?

 

Sorry to bump myself on this guys but has anyone had any ideas. We want to take the quads out for the first time this fathers day and I am stumped. I cannot ride it without brakes. Any ideas would be appreciated. I already drained all the old fluid and put in new stuff. The problem is still there. Could I need new pads? There is plenty of pad on there but who knows?

 

try bleeding the brake line.. maybe there is air stuck somewhere in the line.

 

Thanks for the reply, do you know if bleed them like a car? Three or four pumps, hold the brakes down, then open the valve, close the valve and repeat?

 

im not sure if its the same.. i would think it is since its almost all hooked up the same way...

good luck..

 

Ok I will try it and well see.

 

They can be bled like a car but its a pain...i use a vacuum brake bleeder (harbor freight sells a cheap one) (mighty vac sells a not so cheap one) With a brake bleeder you pull the fluid thru the system.... as long as you dont let the master cylinder go dry during the process your good..

 

Thanks I did it the normal way over the weekend and it feels like I have a bit more grab, but its still not solid. I am going to take the pads out today and clean them good. I will also sand the disc a bit too to remove any gloss. I am going to see if I can pick up one of those bleeders this afternoon at AutoZone and try it. Thanks for the info.
