Hey everyone, I’ve got a brakes question….
this kart used a 4” band brake and the drive sprocket on the right side of the axle, with my setup plan I have I will be switching the sprocket to the left side so the TAV and gearbox will all be on the same side.
i want to change the brakes out but wanted to get some opinions first.

:Keep the band brakes
:change to a mechanical disc brake
:change to hydraulic Brakes

the main issue with the hydraulic brakes is I won’t be able to use the stock brake rod if I Go this route. I didn’t get a picture before I took them apart but the throttle and brake cables were about 18-20” long, they went from the pedals, then to end of the rods then the cables connected at that point. Also I don’t really have room for the brake booster or whatever it’s called for the hydraulics.
i am going to very carefully mount the F/R gearbox handle on the inside of the cab as well as the ignition box, I plan to make a plate under the black plastic inner body and cut out the holes I will need for those items.

let me know what you guys think….

You can keep the rod from the pedals and use a cross shaft and bell cranks to switch sides. Then tuck a hydro brake kit in the rear area.
Sprotors are kinda cool and space saving.

That’s pretty cool, havent seen something like that before, I do see a stopping issue if oil gets on it, as Denny pointed out.

Ordered some parts that will be coming my way soon. New axle, bearings, 4x4 hubs and 4” band brake kit. Me and the boy will hopefully do some engine work soon to, need to install charging coils and get the wires straight for the ignition box.

You cannot hurt this thread by posting more photos. I am realizing that this is not the usual basic fiberglass body over a basic go kart, this is a clamshell deal, for lack of a better term, that encloses the driver and the frame itself is some levels above a basic kart frame. Can you show us some “anatomy photos” of the frame with the lower body or fenders removed?

It’s got a lot of unique features.

Rough mock up while I wait on part, I’m glad I’m at this point because using the gearbox I’m going to have to offset the engine about 2” to the left for the sprocket to clear the frame.
I also laid out where the shifter and ignition box will be. I’m guna have reinforcement plates
on the underside for support for both pieces

Got the axle and bearings roughly installed (nothing tight yet) along with sprocket, unfortunately the “aftermarket “ band brake hub and drum doesn’t line up almost at all, I contacted seller to see what we can do but worse case I can drill new holes and bolt it up.

so looking at the gearbox again, this is going to take some thinking to get lined up correctly, it’s kinda hard to explain but since the shaft of the gearbox sticks out so far and the small drive sprocket is tucked in further it’s hard to see where the sprockets will line up without hitting the engine or the frame. I’ll try to get a better picture soon, I may need to drill some holes in flat bar that I can bolt to the gearbox to help with alignment.

Hey everyone, still in progress with the kart, had some welding jobs come in that needed to get finished before play time resumes. Still thinking on the gearbox issue as well. I did get a chance to tack weld my ignition Box together. Since this one is going to be bolted on, I did it a little bit different than my other one.
i welded nuts to the inside of the box, top and bottom with a rubber gasket and a larger reinforcement plate. At this point this is where I’m at….

Finally had an afternoon to work on the kart, I made some brackets to weld to the frame for the gearbox, spent A LOT of time today and part of yesterday making templates and prototype to get this roughed in, once I get far enough i will make new gearbox brackets next week. Also made a new tensioner for it as well to tighten the chain with. And I’m going to need a new belt because of the center distance of the clutch and driven. So I have a bunch of things all at once that I have been pondering to get where I’m at. As I’ve said before sometimes you just have to sit and look at things and think of how you want to tackle them.
