I put a set of GM disk brakes on the 67 and I'm thinking of running DOT braided lines on the front, all of them from the master to the brakes. These are the 10,000 pound burst variety, tested etc. I have them on the back with the Mark Williams brakes.

I put the motor in the car before I put new lines on, duh, and now it would be a large pain in the butt to retro fit.

Any pros or cons????

Wally, I did the same thing. i have the engine and the huge headers in the car, and the front brake lines aren't routed. I'm thinking that it's gonna be a major hassle to get them around the headers. So have you tried using the stainless braided lines yet? And shouldn't they be of the teflon lined variety? I believe they would need to be either -3AN or -4AN, correct?

I have a 69 Chevelle and I am runnng a Manual Wilwood brake system (13"-6 piston, 12"-4 piston). While I ran my front to rear line with the frame off I didn't have any trouble running the stock line from a "T" to the passenger's side with the engine/headers/transmision/driveshaft and body on the frame. I did use SS flex lines from the "T" to the driver's side and back to the MS. I also used SS flex lines from the MC to the frame where the proportioning valve is. If the front line was hard to get in I would have run the SS flex-lines. I had already bought SS stock lines and tried to use what I could (i.e. rebent the rears, front to rear and the front to passenger side lines just enough to use them).

Okay, thanks for your reply. There's one place on the passenger side where it's really tight. I may be able to re-bend the line. I have big headers that have 2 1/8" primary tube diameters, so that's probably why.

Just a thought...

I would be cautious about running a teflon hose in a high heat zone myself. I would be much more confident of a regular steel or stainless steel line anywhere around headers.

I believe that stainless braided lines can be had with or w/out teflon. But I'm going to first see if I can use the hard lines anyway.
