Stainless steel front brake hose

Stephen Hill · Mar 23, 2017

I am making a custom stainless brake hose for the front brake on my 1972 Combat.
As per stock installation, a short steel brake line runs up from the caliper, then connects to the rubber brake hose.
Is it better to run the stainless hose from the master cylinder to the steel brake line?
Or is better to remove the steel brake line and run the stainless hose from the master cylinder directly to the caliper?
Either will work, but there may be advantages that will only be clear after installation.
Example, if I remove the steel line is the hose more likely to rub on the tire?

I built a steel line to adapt to an AN braided hose at the stock fender bracket mounting point, but getting everything to play nice was a pain, owing to the 37' versus 45' difference of brake line styles. Assuming your supplier can get the hose end to match the caliper, I'd rather go the single piece route, snaked through the bracket at the fender mount. Less joints to leak...

eliminate the hassle and additional joints, run it directly into the caliper with a AN3 male end fitting

All the way to the caliper is the best.

Norton Lockheed (and Triumph) brake fittings have 45-degree SAE tapers, AN is 37 degree.

Could I take a 37 degree fitting and turn a 45 degree face on it? Assuming 45 degree fittings are hard to come by locally.

I doubt you would have much difficulty finding 45-degree SAE fittings.

Steven,
Is this what you want for the caliper end to go from 45 degree to -3AN SS hose?

Rocky Point Cycle is very familiar with the two strategies (and fittings) and can set you up with a plug and play braided stainless (with color options) brake line that goes from the master directly to the caliper or from the master to the bulkhead bracket.

Using the bulkhead bracket and hard pipe adds an additional sealing joint, but is a bit more elegant in that you won't need to screw the master, or the caliper, around the brake line fitting and risk leaving some torque in the braided line; fortunately Spiegeler lines allow for a small radial adjustment, so either strategy will work safely.

Yeah, that's what I was looking for! Where were you when I built mine three years ago?

I'd rather have the solid pipe going to the caliper and an extra joint where the flex line meets the hard pipe at the support bracket. I don't like the look of a braided line threading into the caliper. If it was a banjo connection at the caliper with a braided line, then I would approve... I'm wierd...

Like the CNW Brembo.
