So I'm looking at an Airhart mechanical disk brake caliper for forty bucks plus shipping
and then I see this Stens/Manco mechanical caliper on Amazon Prime for twenty bucks.
I'm only gonna use it to hold back the horses when it's parked for a driver change for instance
or parked on a hill.
So I get the caliper in a couple of days, no shipping, but.......there taint no where to mount the
damn thing! The Airhart caliper has to grooves which allows it to slide on the 'C' shaped mounting
bracket that comes with it.
Question is.....anyone with a mini bike with one of these on it that i can see how you float it on the
disc??????
I'm temped to put it in the mill and put two slots in the casting and make a bracket like the Airhart
caliper uses. Or get real complicated and design a floating bracket of some sort.

Put longer bolts through it and use them to make a floating mount?

The little Model T that I built for my grand daughter has the exact same caliper, except there were holes in the little ears under the arm. That's how I mounted it.

Oh i can engineer a bracket that will allow it to float Charles, I'm not worried about that.
I was just hoping that someone could snap a picture of one mounted on a mini bike or
lawn tractor and save me a few steps. God knows I've reverse engineered enough on
this Cyclekart already!!! And yes, already thought about making a couple of studs from
some 1/2" hex I've got on the shelf, which I could then mount to a some sort of a slide.
If you look at an Airhart caliper, it's free to slide, i.e. center it self up with disk, on the
bracket it came with.

Rick, that was my first thought when I took it out of the box. You can see in the snap shot
that one of those tabs already has a stop pressed into it. Again....you had to make some
sort of a brackt that lets the caliper float on your granddaughters mini T other wise it would
only be pushing on one side of the disk. A disk brake caliper has to float to accomplish
a pinching action with both pads.

I think the best solution is to not waste any more time on this piece of Chinese crap and
spring for an Airhart caliper and just get on with the build.

Just for once Denny, I think Louis has hit the nail on the head with those pocketbike / minimoto brakes, both of them slide on pins on the bracket.

Only of any use for a parking brake though. There are dynamics with brakes which relate to wheel diameter. I am sure the reference will be posted soon smiling smiley

This is just a parking brake Rhys, I could drag a shoe on the ground or carry a wheel
chock with me but.....I gotta do it my way, you know. I've already got the dual hydraulic
disks mounted outside the rails. Just wanted to get a simple, clean bracket welded to
the frame while I'm waiting for material for my wheel hubs.
And......I've just come in from doing a little mock up of that piece of C'#%! that I have here.
Guess I'll spend the day trimming all the fat from the design and making a nice floating
bracket for it after all.
No pics of the go kart/mini bike/lawn tractors???? but thanks anyway!

p.s. Oh...and Chris, those pins are where this cheapo caliper is bolted together, can't
use those spots and the casting is to small to find new places to bore holes.
That's why I'll need a floating bracket. Whatever, it's got to be simple, minimal
and clean looking. Now that I'm retired and have "all the time in the world", I don't do cobble.

Denny, this is how the one I have on the Model T was mounted on the snowmobile that it originally came from.

I modified the bracket, added a bronze bushing, and made a new arm to fit my application.

I attached the arm to the frame with a bolt and nylock nut, left a little bit loose.
It only requires making two simple parts and it allows the caliper to float.

It's simple, minimal and clean looking.thumbs up

It's the only brake the Model T has, and it'll lock the rear wheels easily.

Well thanks Rick, but I'm well into the bracket already this morning. Making an
aluminum adapter that is attached at the bolts that sandwich the caliper together.
That bracket has two holes bored in it that slide on two 5/16 dowel pins
pressed into a bracket that's attached to the frame.
Will work/float great and will only take me a day to make, thus avoiding my
spending sixty bucks on an Airhart caliper. $20 and eight hours labor in the
machine shop!!!!!!! WOW.....WHAT A BARGAIN,
But what the hey......I'm retired now and I got all the time in the world, right?????
Got me a fresh coffee.....back to work now.
G'day

I think ya'll might like to hear something from me
nice and easy but there's just one thing
Ya see, I never ever do nothing nice and easy

So I'm gonna take the beginning of this build
And do it easy
then I gonna to do the finish tough.

Woops, didn't I hear that some where else?????
