Bolts arrived today and I made time to install along with a salvage master cylinder which appears to be a Drag Specialties item.
One woe seems to follow another. Couldn't get the connection at the master cylinder to stop leaking. And I noticed a crack going through the disk.
The disk still seems to run on the warm side.
I may sideline this project for a while. I was going to take a 500-mile trip with this bike but it seems like a bad idea at the moment.
The handlebar wiring harness I installed has had the Run and Brake light switches fail already which makes me uneasy.

Does anyone know how to spec these Goodridge brake lines for an '81 Ironhead layout? This is a right-side master cylinder crossing to oil tank mounted tee with brake light switch then on to the rear brake caliper.

Has anyone tried to rebuild the the nut holes by pouring babbit material in there ( coating the nut with something like copper stained glass copper trim) ?

I don't think those calipers are worth rebuilding, they were not very good when new.

Could you JB Weld the nuts in?

VTwin has GMA? replacements

Or you might look at a 82-86 retrofit

On my 1980, I was never able to get the JB Weld to hold on the brake calipers. Too much vibration I think.

You are probably right. The nuts are a minor issue as you can pin them from the back with a long screwdriver. They do not function as bolts. They function as pins in a floating caliper design.
I would like to get through this riding season before moding the brakes.
On a lighter note Goodridge lines for the front calipers from the t-fitting down are available for $65ea.

Has anyone installed the GMA caliper on their bike. The description mentions it requires a 5/8ths bore master cylinder to work properly.
