Many Questions

Okay.. again:
They WILL fail! (not an "if condition" that's a "when condition")
And by case of emergency I mean, you're going a tad too fast, the road is a tad too short and you are going to be hurt and not just a tad .

And to be clear on that, professional hydraulic downhill brakes may stand the force you need.
But that's NOT what is mounted on a regular mountainbike,
that is what I consider professional bicycle brake (I wouldn't try those either to be honest):
http://www.vitalmtb.com/product/guide/Hydraulic-Disc-Brakes,11/Formula/2013-T1,11399#product-specs
(take a look at the price tag.. one brake +master cylinder, no rotor!)
So after all if you mount the "right" bike brakes you'll spend around 1200 USD

for that money you can buy a used quad with enough braking power to stop your kart easily, and you'll get a motor on top, and wheels, and maybe a steering setup, and suspension and....

anyways, try it if you want, but don't hurt yourself.

Ok thanks for the warning. Will having 2 brakes on the back be better than 1? These are gokart breaks I'm taking about...

 

[itsid]

Depends, if you have a mechanical brake maybe, a hydraulic brake I doubt it.

I think band brakes or drum brakes can be doubled up without any issues.
Hydraulic disks on the other hand may cause problems.
Because the large scale hydraulic brakes if used in pairs may completely lock your rear axle.
That is indeed a faster deceleration than with a turning axle of course,
but the kart may loose traction and most of all, you may need new tires afterwards

So if you think one kart rear brake will not be sufficient, I'd add front brakes (that's where almost 60% of the laod will go when you hit the brakes anyways)

Yeah, I know. My reason for wanting to use bike brakes is because they were small and relatively cheap. Because they were small I could put them on the front wheels relatively easy. If there is a thread that has a guide or something about using front brakes I would love to see it. I haven't been able to find one on the site anywhere.

Quick question…

If I get one master cylinder and one caliper today then if I get two more brakes for the front then do I need two more master cylinders?

 

[itsid]

One more for the two front calipers.

[hackintoshMan]

Why one more? Can each master cylinder handle 2 calipers?

 

[mysteryboy28]

you want seperate front and rear master cylinders - or at the very least seperate pistons in one large master cylinder, in case a brake line ruptures, or a caliper fails. that way you're guaranteed to have at LEAST front or rear brakes - for a moment anyway (till you run out of brake fluid).

Oh I see, so it is making a redundancy?

And if I want to move the fuel tank and I end up needing a pump then how does it operate? Does it need a battery?

 

[hackintoshMan]

When you build a go kart, do you order all of the parts at once or do you buy steel and make the frame, then buy everything else in sections?

 

[mckutzy]

IF money wasnt a barrier, id say get everything till your hearts content. But if your on a budget, get what can get you going make do with what you got till the next buy or scrounge session.

 

[hackintoshMan]

Ok and I could see myself getting parts and then they wouldn't work

 

[chris_the_poser]

Just ask before you order and we will help you and tell you if it will work or not

If you're running a live (solid) axle, A second brake becomes redundant unless the one is severely under efficient; it's very easy to have overefficient brakes...

When you build a go kart, do you order all of the parts at once or do you buy steel and make the frame, then buy everything else in sections?

I find it's better to build around the major parts; nothing worse than having to undo work coz a part doesn't fit... but that's just me...

 

[hackintoshMan]

Does this frame look OK? The design is from blackley1's frame.

 

[OzFab]

I haven't studied it in great detail but, from what I see, it looks pretty good
