I have a 1965 fj40 and am converting it from a single master cylinder to a dual master cylinder. The flexible hoses are kinda weathered. i know that they use a 9mm fitting on the hard line end. The end that goes into the brake cylinders are those also 9mm? Or can i take new flexible hoses and then just convert them to 10mm? And then just run all new lines?

Thanks for your help and input

Hey matt, Yes, you can use a new flexible hose and convert them to 10mm. That is actually recommended so your system will use only a single type of brake line fitting. Plus your new master cylinder will use 10mm so you would have to make a transition at some point.

In my thread, I converted to a dual master cylinder with a brake booster/ all 4 wheel disc brakes/ new lines/10mm fittings. It is not the hardest thing in the world, just a little time consuming.
 
So just to clarify the fitting that goes to the brake wheels cylinders is 10mm to 9mm on a 65 fj40. And if i use a new flexible brake fitting its 10mm into the brake wheel cylinder to 10mm is that correct?

My wheel cylinders are all brand new for a 65 fj40

Thanks

The fitting that goes into the wheel cylinders is 9mm, all the fittings on a 65' should be 9mm for original equipment. If you use a new flexible brake line, you would need a 10mm to 10mm, then an adapter to go from 10mm to 9mm. I do not believe that there is a 10mm to 9mm flex brake line.
