Why the cork screw in the master cylinder to distribution bl

Post by born4ford »

Hello Slick geniuses,

I'm busy making new brake lines for my '65 F250. I added a dual reservoir master cylinder a while back. The old line going from the old single res MC to the brake line distribution block was wound around 3 - 4 times, like a corkscrew. Is there a reason for this? I think it would look cleaner to make a more direct line but I need to know if the corkscrew added fluid volume or something else that isn't obvious to me.

Oddly, Googling "why is there a cork screw in my brake line" didn't produce anything.

It's there to dampen any vibration the line is subjected to, which could in turn result in a stress fracture = rupture = loss of line pressure

Thanks. Makes sense. All the other lines have multiple brackets for the vibration, I guess.

It also helps compensate for the flex difference between the cab and chassis as the cab moves on the rubber mounts.

Another good point. I figured that Ford wouldn't want to waste steel line just because they thought the spiral looked good.
