As far as the brakes go, it looks as though you have a mechanical caliper. From the pic it seems as though the wear pattern on the rotor is not right on the outside edge. If the pads are okay, and the caliper is working correctly, it seems you could increase your braking power by mounting the caliper slightly further forward so that the wear surface on the rotor is right to the outside edge, this will give the caliper sightly more "leverage" on the rotor. It would cost you nothing, but a little time, to find out. BTW, good job on the jackshaft!

That's what we're all about; sharing information & experience so others don't have the same problems. It's give & take; we teach as well as learn (well, maybe not so much of the learning for toystory ).

I have learned quite a bit thanks to the fine membership of this forum, and still learn things! There's a phrase I use periodically- "Nobody is good at everything". I think we can safely alter that to read: "Nobody knows everything". I don't care how smart, educated, or experienced a person is, there's always a weak point. I hold the highest respect for he who can admit it.

Well said & very true. I have 25 years of professional experience when it comes to mechanical, welding & fabricating but, even with all that, the guys on this forum have taught me so much in the last 6 months I can't begin to explain...

Best forum ever

I found one on Ebay. 24 tooth 5\8" bore. This should torque me up. Also found a bigger brake caliper. It's heavy duty and comes with mounting bracket that allows it to slide a bit to keep it from binding on the rotor. 14.99 for sprocket and 41.99 for the caliper. Hopefully it don't take me a block to stop it now.

Good! Because frankly, a single-piston caliper that does not feature either a floating bracket or a floating rotor, is a total chunk of spit! Poor engineering, nothing but. You've got a piston pushing from one side, but no consistent method of equalizing the pressure from the other side. No wonder you couldn't stop!

Incidentally, (lopsided caliper aside) you would increase the braking force by moving the caliper as far outboard on the rotor as possible. Think leverage.

Wow, I didn't see page 2 on here when I posted my last post. Will try moving my caliper out to the edge of the rotor. Will let you know how it turns out. Although, I think I will get the new caliper on its way. The brake pads on this are only about 1\2 as big as the ones on my other kart. These may work on a light kids kart or something else. I throw away nothing... Oh, and thanks to all for the very useful info. Off the subject but does anybody know anything about pinion angles in automobiles?

What about 'em?
