110cc Go Kart Brake Issues!!!!!
 

My frist question is how to take the calipers apart? Next… on this go kart there are two disc on the front and one on the back. So there are 3 lines. I have tried bleeding all lines and no luck. I have look for any leaks and none. I did notice the washers on this go kart where a little different. These have a rubber ring on the inside of the washer and all my other honda atv's have brass/copper looking washers. Should i replace them with the brass/coppper ones?
