I am Bending my own hardlines and I was wondering

I know fluid does not move throughout the whole line but would longer brake lines effect tempurature of brake fluid?

basically since there is more fluid in the lines will it work any differantly

It shouldn't matter unless you're using a brake fluid recirculator system.

 

technically increasing the volume of your brake system would increase its potential for heat dissipation but I don't think the change would be noticable. If you've got a bunch of time on your hands you could make some really cool little aluminum foil cooling fins running the length of the line. or not.

 

In theory the hard lines *could* dissipate some heat. But fluid gets hot and boils in the calipers, not the lines, so I cannot imagine any measurable cooling advantage to using longer or aluminum lines to shed some heat.

My concerns would be making them serviceable and routing them out of harms way.

PS: I've asked a few World Challenge guys about using aluminum vs. steel hard lines. The rule of thumb is to use steel for fuel and aluminum for everything else.

What's the reasoning behind that? Weight savings?

 

Does steel or aluminum transfer more moisture? I know for a race car it doesn't really matter because they change the fluid quite a bit.
Adding more line (I would think) could change peddle feel as well.

Yeah. Easier to work with, too. I didn't think to ask if there's a cost difference...

The amount of hard line wouldn't affect pedal feel, the amount of rubber brake line would.

BTW, I just used mild steel for my brake lines which is what comes stock I believe. It didn't weigh much at all.

 

you can also run braded lines the whole way but that gets pricey

And braided lines still flex some compared to hardlines.

 

You guys are all drunk. Matt Nicholson uses pee for brake fluid. It's supercooling and non-compressible.

 

If you are using Aluminum tubing for anything, make sure:
1. The pressure rating is good enough. The booster on power brakes car can really generate some pressure.
2. Make sure you brace the tubing correctly and there is no contact to other materials. The aluminum tubing is very prone to abrasion. Since everything on the car is basically steel, if the two touch the aluminum is the one going to give.
3. Make sure it is out of the way so it is not in the way when you do your regular maintenance or taking engine in and out. See #2.
