Look good and clean. I've been thinking about doing this latly. I hate having clutter in my engine bay. Plus mine it making some noises here and there.

In giving up ABS you give up a slight margin of safety... but then again, FD's are so well set up and usually run such good tires that its not that much of an issue.

Just make sure your bias is set up right if you get aftermarket brake stuff, use good pads and tires, and learn to threshold brake. Nothing beats stopping on a dime with that slight sound of the tires partially locking (limit of traction).

Somehow, I think Jordon will be OK in this area.

I'd imagine you can just get some bulk line and bend, cut and flare to your liking.

That's what I'm doing this winter. Might put in a line lock too. Can't wait.

Vosko put in a line lock didn't he?

Question. I was under the assumption that brake lines to the left and right side of the car should be equal length. Unequal length lines could result in uneven line pressure between left and right sides of the car equaling uneven braking left to right. Hence the reason we see OEM brake lines coiled in certain sections?
*shrug*
Personally I don't see the point unless this is done on an all out race car for weight savings and used in conjunction with dedicated MC's. Someone help me out...why do this?
Regards,
Crispy

Negative. As long as the calipers are identical, the hydraulic pressure exerted on each should be equal throughout the system.

I agree, but it's a free country I guess...

Kento explained that's not true (hydraulics don't care about the lengths of the lines, just the sizes of the pistons) but the coiled lines serve a purpose. These were frequently seen on older cars and the coil in the line helps limit the amount of fatigue the line sees due to vibrations or movement between two different parts. For instance you might see a line with a coil in it right out of the master cylinder before it runs down the firewall. The coil can absorb much more vibration and movement without breaking than a simple bend can.

Me neither. Of course I've seen plenty of dual master systems that also show people had no idea what they were doing either...

All the ones I see fall into a few catagories:

1) The inane belief that anything modified is better than it was before

2) My ABS is not working properly and I won't fix it, I'll discard it! Cheap and easy!

3) My nuts are bigger than yours because I can drive without antilock brakes

4) My engine bay is so danged pretty now that I threw away everything but the engine!

Thanks guys. I understand that the hydraulic lines aren't concerned with the length in general but moreso when speaking of overall brake performance disparity due to the lengths side to side. Specifically anything that migth indroduce inconsistant braking side to side like perhaps more propensity for contaminants in a longer line, thermal expansion of the fluid as the system heats up that may have an effect...I dunno...talking out my a** I guess
The fatigue issue of the metal lines themselves certainly makes sense though.

Oh and I like the reasons suggested for doing this...or lack thereof

Pascal's Principle states: A change in pressure at any point in an enclosed fluid at rest is transmitted undiminished to all points in the fluid.

If piston #1 has a wieght of 10kg pushing down on it and the Area is A and the Area of piston #2 is 50 * the area of piston #1 then the weight on piston #2 has to be 500kg to reach equilibrium.

I was bored.
