disc braks

[jeffm352]

im looking for a 3/4 bore brake disk for my axle. im running a brake band now but with a 16 hp motor i dont think that will have to much stopping power. ive looked every were on line with no luck. they are all 1 inch or bigger.and changing my axle to 1 inch is not an option. thanks for all input

I have not looked, but can you get a 3/4" hub of some sort that a disc can attach to?

 

[jeffm352]

i havent bin able to find one on any of the gokart sights.a hub is one thing getting a disc to fit it is another.you would think some one would make a 3/4 bore disc brake set up for karts. but i will keep looking

Why is 1" not an option? How bad do you want better braking?
Try this-
1) Get yourself a caliper, any caliper
2) Get a sprocket hub for 3/4" shaft
3) Use a SPROCKET for a brake disk. (I'm about to do this on my kids' kart)
4) Stop better.

Cheers! Chris

How about cutting a 1/4" keyway section out of a bushing like this: http://grizzly.com/products/G2450
And then use it to adapt a 1" rotor hub to fit your 3/4" axle. You'd then just need to find some appropriate 1/2" x 1/4" bar stock for a custom sized key to lock it all down to your axle.

Depending on how your rotors set screw system is designed, you might also need to drill a hole(s) through the bushing and use longer set screws if necessary so they go up against (or possibly through) the axle just like origanaly intended.

here you go for a disc: http://cgi.ebay.ca/Go-Kart-Mini-Cho...s?hash=item5ad2cb6a88&_trksid=p3286.m20.l1116

and here you go for a caliper!: http://cgi.ebay.ca/1995-1998-Honda-...ries?hash=item5ad1fee125&_trksid=p3286.c0.m14

i have the same disc with a raptor 660 caliper on my shopping cart and the stopping power is just... overkill!

16 hp...I think changing the axle is gonna be an option in the future.

lemegacool that disc is a 1 inch bore, i also have a 3/4 inch shaft on my kart and the best solution i can think of is using a 1 inch bore disc plus a bushing to reduce it to 3/4

 

[jeffm352]

why you dont think the 3/4 will hold up with the 16 hp motor.so i should start collecting the parts for a 1 inch axle now.

oops yeah i forgot i got a 1" axle LOL

if you go the bushing route, you could put 3/4" locking collars on either side of the disc hub to hold it in place. you still need a key to keep it from spinning.

i got it. i can burn a coller on the plasma table the thickest i can burn is 3/8 steel. a 3/4 bore and a 1 inch O.D and weld it on a disc. that should work as long as its true right. do you think i can make my own disc out of like 12 gauge steel. just thought of that one. i can burn most any thing at work.

Use a sprocket - turn off the teeth if you want
