Looks like you have a 300x that is stretched to a drag bike. The jack shaft requires the wheel to be flipped to the other side for the wheels sprocket to line up with the jack shafts secondary sprocket. Flipping the wheel makes the disc brake obsolete because there is no sprocket for the brake to stop. There are a few options you can do. 1) Take the jack shaft off and flip the wheel back and install a disc brake 2) move the disc brake mount to the other side of the frame and put in the Kelsey Hayes 200m original disc brake setup. 3) just install a band brake setup on the clutch and leave the disc brake off.
Awesome bro. Thanks for all the information. So I’m planning to remove the Jack shaft and flip the wheel and restore the disc setup. Any idea where to source the caliper? If it’s no trouble I’m going to shoot a pic of the weldments on the frame if you could let me know how they look to you? Thanks again!
It looks like your brake mount has had some work done to it. The welds are sloppy. It may have been added in or relocated at some point, and the additional mount located behind the axel on your bikes frame does not belong on the bike. I’ve attached a few pics from my bikes that show original locations for the disc brake mount on both sides of the frame (red 400x & black 400TS). The Kelsey Hayes 200m is a difficult set up to find. Someone here might have one they’ll part with or others here have modified aftermarket disc brakes to work. I’ve noticed The original disc brakes never work that well. They’ll slow a bike down, but I just don’t think they have good stopping power. I don’t run the disc brakes on my bikes. Instead, I’ve converted all my bikes to a clutch band brake setup.
