Nicked Hard Brake Line From ABS Actuator Curly Q

Well I nicked hard brake line going to the drivers brake rotor, you know the extra long one that has the crazy curly Q circles at the end. I went ahead and ordered one from some dealer somewhere. My question is is it possible to bend that whole set up on your own or just bite the bullet and get it from the dealer. If I went out and bought the tools and the tube it would have ended up costing more up front but down the road if I do it again it would pay for itself. Also why does Toyota make those crazy long ass curly Q lines lol

 

I'm not sure about the toyota brake lines but i know in pneumatic lines they put a loop in certain areas to trap condensation and such. Id be interested in what you are thinking of doing and thought about getting into the tubing trade but I don't think I would start learning on my brake lines. Maybe start on someone else's lol.. just kidding. There is definitely an art to it. Always good to have a new trade/new knowledge as long as you practice first id say

 

Might get more input to your question if you had a title like your first sentence? Good luck either way

 

Personally, and this is just me spit-balling here, but I believe the reason they add the loops into the brake lines is to add length to the line. Based on my observations, all brake systems that I've seen will have the brake master cylinder and a looped line near the brake on whatever side of the engine the master cylinder is on. I can only guess that it is because when the master cylinder activates and pushes the hydraulic brake fluid to the brakes (at the 60/40 split or whatever the proportioning system is set at), the increased length allows both front brakes to actuate at nearly the same time, that would be my best guess. The brake lines will constantly have brake fluid in them because you don't want to wait until the system pressurized before actuating your brakes in emergency situations. So that loop being a condensation collection point wouldn't be viable. In addition to it not being a condensation collection point, water in the brake lines isn't good for the brakes too. Water compresses differently than hydraulic brake fluid which is where you get the "spongy" feeling in your brakes. A second reason for not wanting water in your brake fluid is that it will cause your brake components to rust out from the inside leading to a failure of the system.

Thanks for the feedback, editing probably post a pic too

 

Yep, I also read because its hard line and the rest of the car is always flexing and moving it has to have "cushion" like the mater cylinder moves, the fluid moves etc. and it needs that flex. I'm wondering if I could put something similar together until I at least get the new part? Maybe I should just buy the tools and 25 foot of line and practice with it. I can't drive the truck anywhere at the moment because no brakes, glad I'm about to go out of town for a week because I hate waiting on dealer parts lol

 

water doesnt compress at all, its air that you're thinking of.

Tiny air bubbles get in the brake lines because the fluid actually boils when the brakes get very hot, like during panic stop situations

The coiled up sections of line are there when some flex is needed.

 

Try nickel copper brake line, easy to bend easy to flare, no rust.

 

Some time back vehicles, OEMs, started to come with coated brake lines to prevent rusting.
