HPM guy just told me that he is machining up a run and they will be between 30-35 clams including hardware. I'm on the list. If any of you other FFs want one better shoot him a PM so he knows how many to make.

Brake lines I buy at cyclebrakes.com--excellent customer service and they can make custom ones for a nominal fee.

Hello All,

As SoloLobo has mentioned, I will be producing a batch of the adapters for this conversion. They will be CNC machined, with radiused ends and, as requested, will have the blind hole for the top bolt. I have sourced the fasteners necessary for the conversion in zinc plating, and they will be included in the cost of the adapter.

I would appreciate it if anyone who has already purchased a caliper (Tokico or Nissin), could measure the thickness of the mounting ears where the M10x1.25 bolts attach. I need this measurement to finish the design, and to make sure I purchase the correct length bolts.

Please email or PM me if you are interested, and I will put your name on the list.

Regards,
Guy

Adapter

Guy, I have both, mounting boss thickness is.

Nissin: top hole 13.47mm bottom hole 13.08mm

Tokiko: Top hole 15.35mm bottom hole 11.80mm

Now fire up that mill we're waiting for REAL brakes. Thanks, Doug

I purchased a braided line from cyclebrakes.com - good product, service and price, but ---

the banjo was slightly thinner than the OEM and the bolt grounded out in the hole just as I was applying final torque - so measure the OEM before you fit the new one aqnd shortten the bolt if necessary .

There are several on eBAY, but they don't always give you the information you need.

Spiegler and such will cost approx 15 more than ebay people, but you get a better service and lifetime warranty.

I may have missed the memo, but AFAIK it is NOT tribal knowledge that there are different sized banjo bolts for different brake systems.

The airhead GS caliper and master cylinder require a 10mm banjo bolt at each end. banjo ends vary slightly as to their width, so you might need extra crush washers to shim.

To get rid of the metal brake line on my GS, I just got 2 10mm ends and a second bolt (screw) and ran it right into the caliper.

You can use plastic tubing to make a mock setup to decide exactly how long of a line you need. Centerstand, front end hanging at full extension, and then run it just like you want it and measure.

Brakeline length is measured from center to center of "eyes" on banjo fittings.

with the stock GS fender that has the rubber grommet in it, you can run the new line through there, and everything works fine and approx 37" is perfect. Just make sure you put a 90 or at least 45 degree bend in one end if you need it to reduce the bend in the line or get around handguards.

My 1990 GSPD has a flaired fitting at the master cyl end.
My local brake man made my hose with a flair nut up top, and a banjo at the caliper end. Works perfect.

Pic please. I don't have any idea what a flaired fitting is.

Flared fitting. You flare the end of a piece of tubing to look like a trumpet horn. That fits onto a dome like threaded piece and is compressed with a nut.



Its the nut job on the metal tubing in this pic:



They're a good joint, as long as the flared part of the metal tubing doesnt split.

Not just copper

Do not use plain copper tubing and fittings, as in water lines. It is not made for the pressure and will work harden and crack. Not good. Steel, stainless or best if you can find it copper/nickel, like Volvo has been using since the 70's. I just redid my old Rover with some from Automec, really easy to work with and lasts way longer than the other stuff.

You should allways use a double flare. And use proper brake tube.
My brake shop made me a braided line with crimp fittings.
He is a licensed hose maker.

Sorry, dont have any picks at the moment. Must do some.
