Rear Disk Brake Hard Lines

wompninja · Posted: Tue Mar 24, 2015 7:20 pm Post subject: Rear Disk Brake Hard Lines

Has anyone installed the CB Rotohub rear disk brake kit? How did you route the hardline? It seems like they gave me about a foot too much line. What's the best way to do this? Just a big loop down into the caliper?

is the end of the hard line flared? You can get a flare tool at Sears for semi-cheap

Yeah it's flared, I have a flare tool so chopping it is not a problem. I just don't know if having a big loop hanging off the end is a good idea since it'll be so close to the tire.

Just don't use it ,, buy a front disk brake flex line and use it in place of what was in the kit,,I did it fit perfect, and I thought it should have been flex to start with,,,
Good luck

I wonder if the rear brake lines have to be equal length.

But yea, loop it so it's nowhere close to anything moving.

No I don't have any pics as I'm in Hong Kong right now and the car my 70 vert is in Oregon,,I'll be back in a week if you still need pics .
Its simple just get a pair of front disk flex lines they are just a bit shorter than the ones for drums and turned out to be a perfect fit,,

Good luck

And, no the lines do not need to be the same length. It is a closed hydraulic system, so length plays no part in this equation.

I'd run it. I like hard lines because they don't bubble. Also if something happens, say a line fault, you can pinch the line.

DON'T use the hardline at the caliper! The caliper is supposed to slide freely to prevent pads on one side dragging. The hard line will fail prematurely due to the stress and vibration,thats what the flexible brake lines are for.

Have to agree with that, if it is currently a floating caliper, a hard will def prevent that.

Good to know, I thought it was a little weird. Now I just need to find a brake hose that will work.

I got these from Jon at Topline. Great for when you need to remove the calipers without undoing the hardline and re-bleeding.

I have that setup and here's a pic of how it is bent:

I have 6.5" wide rear wheels and there are no clearance issues. Not sure if a hideaway muff setup would clear it, but I think it would.
And as far as this setup stopping the caliper from sliding, that isn't an issue at all. The movement of the caliper from the brakes being applied is so miniscule, it couldn't possibly affect the hard line attached to it. There is more than enough flex there to even pull and hang the caliper away in the wheel well to work on the rotor, bearing, etc. like I did.
The stainless flex line isn't a bad idea, I just don't see the benefits of them being installed justifying the cost.

You are right, they aren't necessary but neither are rear disc 😋
I went through two sets of hard lines then went to the stainless. Much easier but each to their own.

To bad no one makes a rear disc brake kit with backing plates to give it that oem look. Sad
