I am converting to disc brakes on my 71 Nova. Right now, it has a drum master cylinder with no booster. I have ordered a disc brake master cylinder with a booster, and was wondering about the brake lines? Obviously the booster/master cylinder will extend the position a little farther away from the firewall. Will I have to get new brake lines, or is it possible to bend the lines or somehow make them fit?

I'm hoping that the stock lines will be okay to use.

thanks

You should be able to stretch them, if need be (there is a coil in the line to limit stress on the lines from body flex). If you need to change the ends (metric or different size fitting) you can add a 6" piece with a slice made up of Weatherhead™ brass fittings from your friendly neighborhood NAPA jobber. As far as that goes you could use steel AN fittings and Teflon™ lines braided steel hose designed for high pressure (power steering out put and brake lines exceed the rating of normal braided line) to dress up the package a little and splice back into the line closer to the frame (be sure to use a double flare on the line were you splice).

are you buy everything as a kit? if not you will need to get a different proportioning valve. also the size of your lines will be different.

i cant remember the exact size of the fitting though

I am getting confused with the location of each brake line. The old setup was a no power drum/drum prop valve, and i'm upgrading to a power disc/drum prop valve. I have noticed that the old setup had the brake lines in a different order. Is my assumption correct?

thanks

Didn't I mark the line ports on the valve I sent you?

No offense, but if you have 35+ year old steel brake lines on that car it wouldn't hurt to put in new lines. You start trying to bend lines that old and you could very well cause stresses in areas you don't see and cracks or weak spots could form! Would hate to see you go for a drive and have the brakes go out and it seems to always happen when you need them the most!

Philip you did mark the location of each line on the prop valve. I am just surprised how the old brake lines are backwards in relation to the new location, and was wondering if that was normal. It is a little confusing and frustrating looking at the bare lines for a "rookie" like me. :D I just like getting a second opinion about my progress, and double checking my work.

Thank you for the bracket, it came today. I am going to try to tackle this job today.
