M54A2 Brake line size ?

[firefox]

I have to go work on my brakes in the next town over
where my truck is and want to go prepared.

What size is the brake line?

Thanks a bunch!

Impossible to help with that information. It all depends on which line, there are 3 sizes of hydraulic lines on the M54 and then the air lines for the brake system.

Thanks! I don't even know if I have a leak, or it's just air in the lines.
All I was told is that the pedal went to the floor with no resistance.
I was hoping that all the hydraulic brake lines were all the same size.
Now I know that they are not.
