I should be receiving my front brakes lines in the next day or so. I'm starting to look through catalogs in anticipation of ordering the remaining lines and looking through them I notice that the front to rear lines can be ordered as either 1 pc or 2 pc.

Why the difference and what's preferrable?

Thanks,

John

Bump for getting an answer on this. I too see that brake lines are sold as 1 piece or 2 piece front to rear lines.

My 1969 (factory p/b and A/C) has 2 piece front to rear lines originally ---- read on this forum that it is because "1969 Firebird A/C cars had a prop valve on the 'frame' under the driver door".

Called a Disc Brake Proportioning Hold-Off Valve. From a website: This brass valve controls the hydraulic pressure to the rear brakes to evenly distribute braking force front to rear to keep the vehicle level during braking on models with a heavy front end.

So is that why was it on A/C cars? Assume I can delete that valve and run a 1 piece front to rear brake line if desired, since I have a Wilwood adjustable proportioning valve at the master cylinder for the rear disc brakes.
