Hi..I have a 2005 Champion trike kit for my 2005 Goldwing. I put new tires and pads on both rear wheels and bled the system very thoroughly. The braking improved quite a bit. However, what I did notice is that when I step down really hard, the left wheel locks up, but the right wheel does not. It does this consistently. I even noticed it before the new pads, bleeding and tires. Road condition is dry at all times. What can be the issue with this uneven braking? Thanks
