Brake Hose AN859-4D-10

[6643]

how long are they?

I believe the -10 indicates 10 inches, but I could be misremembering...

Ok what is the correct setup for these? I'm guessing a 45 degree angle at the caliper and then make shorter hoses? These hang out in the breeze and probably cost me 1mph

At least!

Mine have a 45 at the caliper. IIRC, the -10 in the part number indicates 10 inches from the centerline of the 45 degree fitting to the sealing surface of the straight fitting.

I agree it is probably over 1mph in cruise.

The new hoses and 45 degree fittings just showed up so I will transfer the ends to the new hose and hook it to the 45s. Haven't bled these before but I imagine there is some sort of ripple so maybe I will use the pressure bleeder I use on my cars.

Sounds about right. The end fittings add some length and I think I measured it at just under 12" to the fitting ends guestimating where the 45 fitting will connect.

Don't mix hydraulic fluid with automotive brake fluid!

Years ago I bought a large pump-type oil can and a piece of plastic tubing. Drain all the fluid out through the caliper bleeder then fill the oil can with fresh fluid and pump it up into the brake reservoir. Easy-peasy. Just make sure you have enough fluid in the can to do it in one go because if you have to reload you'll probably introduce an air bubble.

Ah yes. I noticed this thing takes hydraulic fluid. I have a can so I will see if there is some small tubing around that I can use to pump it full. Thanks.

Well, using the little pump oil can didn't work at all. Either it doesn't generate enough pressure or it leaks back through the pump too quickly. Not at all what I expected. Guess I will buy a better one at harbor freight and try that.

Are you sure the master cylinders are returning fully? If the pedal doesn't return then you won't be able to pump any fluid up. The pressure required should be less than 2 psi.

This one works surprisingly well:
