Hi, I have a Heald Super Tryke that I use like a small tractor, the problem is that it hase mechanical drum brakes that are poor at best, wanting to change it over to hyd disc brakes. I can get a master cyl for a reasonable price but the calipers are just too much money so I've been looking a cheap Chinese calipers now the here's the question they have metric banjo fitting and that will not work so can or is there a way to change over to US flare fittings?

(quoted from post at 15:44:07 02/08/13) Imperial measurements were British before there even was a
USA.

And yet the Brits have yet another entire series of plumbing than we do..BSP.
 
Any good hydraulic shop should be able to make you up hoses with whatever ends you need on them. I use Colliflower,they are on the east coast and they have made up brake hoses for me, and have a machine to pressure test the hoses after assembly.
 
This is the only time I've ever heard some one that makes up brake hoses in their shop for a customer. I hope they test them for up to
10,000 lbs of pressure.
 
You are in MN? Snow mobiles changed from mechanical disc brakes to hydraulic disc brakes about 20 years ago. Both styles are reasonably easy to mount on a shaft. If your trike runs at slower speeds a mechanical brake off a larger sled might be more than adequate.

Motorcycle disc brakes would work too, they might be harder to mount the disc.
 
I'm watching this one with interest. I have the Heald three wheeler my dad bought us boys through the mail. It works good to pull a yard cart but those brakes are the worst. I wore out tons of shoes stopping that thing as a kid.
 
Suprised someone else did not answer. Real easy solution. The banjo bolt that screws in can be taped there on the end to accept what ever us fitting you want. Takes a small short piece of open like pipe to fill in where the original pipe would go.
 
Always wanted a Heald kit bike as a kid. Never expected that there would still be some around?
Wonder what ever happened to Heald?
 
The Brits do like their own little twist on things . Very similar
but just different enough to be non compatable , slow down
progress and require extra inventory.
Whitworth threads, the 505 Gibs instead of the 50bmg and
the Webly 455 instead of a 45 colt. Then just to add insult to
injury, they drive on the wrong side of the road.
 

Thanks for the replies guys, I had a set od f disc fabricated and my original plan was to use a couple of simple mechanical calipers but the location of the brakes just would not work no matter how I tried to locate the calipers. Mounting the calipers is not the problem is routing the cables that couldn't done. I researched motorcycle and snowmobile brakes they are too large to fit in the area and I can have new OEM caliper made but at $100.00 each it more than I want to pay.
The idea of drilling and tapping the original banjo bolt is worth looking in to I thought of this, also if there is enough material the caliper maybe could be redrilled and tapped for 1/8th inch pipe thread. As for having a hyd shop make up new lines that would cost more than I want to pay, and I sincerly doubt that they would need to be tested to 10,000 PSI this is a thre wheeler not a 3/4 ton truck.
