Default Re-routing brake lines

Yes, it could by my OCD kicking in but I've always felt my car's brake lines needed to be relocated. Two reasons; one cosmetic, they've been bent and reshaped sometime in the past (ugly). Two, didn't like the proximity to the headers on the passenger side.

So, when the brake master started leaking I removed it and before I knew what was happening, I'd pulled all the lines from the engine compartment all the way back to the tee on the right side of the rear subframe.

I've bought a 25' roll of copper/nickel 3/16 tubing, already had a good flaring tool kit so now it's time to go to work. The plan is reshape the bracket on the passenger side/front so the line can connect outside the frame rail and route the lines from the master cylinder to the right side of the car using the windshield wiper area below the windshield.

We'll see. RR

I really wanted to do this too but I decided to wait till shes up and running. After bending all my fuel lines I couldnt get myself to do it all over again! I'm interested to see how you route down and out of the wiper area to under the car...

I have found that if you first mock up your lines out of some wire coat hanger, they are much easier to duplicate out of the actual tubing.

When I ran my new lines, to avoid the crossover at the firewall which I feel is redundant, I went down from the brake master and ran back along the outside of the driver side frame rail. Then reversed the crossover line that runs alone the back axle carrier. Just had to fab one bracket in the back where the line tees.

Makes sense to me. This is in the works for me as well. I've really wanted to keep ABS on my NB, but its looking like it will be difficult with modified axles/hubs I have. I'll come up with something, but haven't figured that one out yet.

As to why, If anyone else is driving my car, they are going to be expecting abs, and in rain/ice/snow we inevitably get, its a good aid to have. If I could get a good 4-channel setup, it would actually be a benefit in many cases.

Great idea on the reroute behind the fire wall instead of in front of it! Not that I would ever make any effort at tidiness but it is a really good idea.

It's done. Not to bad a job, just work. As was suggested by jreid1000, running the rear line down the outside of the driver side frame rail is a great idea, to bad I was already committed when he posted this excellent idea.

Lessons learned...make all holes for lines 1/2", this allow a bit of wiggle room and makes it easy to utilize grommets. Take Tbone's advise and make a wire pattern for bends out of coat hanger wire. Take your time and have help available when pulling tubing, it's a bear by yourself at times.

Was it worth the effort, I don't know...I'm not particularly satisfied with my results or rather my craftsmanship. But I consider it a success as a proof of concept. Now lets see how many images I can post. Oh, I do still need to make a shield for the lines near the right front wheel and the larger line is the fuel line I rerouted. No lines crowded by the passenger header now
