Brake line question...

[joescott]

Hello all
I have a 1967 gmc longbed. In an effort to get better brakes I got new shoes. When I went to install them I found I needed wheel cylinders. these led to new rubber hoses. and this has now led me to new hard lines. When I am done this truck will have all new brake stuff.

My question is this. I have small hard lines running the front brakes but a larger diameter line going to the rear axle. Is this normal?

Thanks
Joe

Yes!

Think of it this way: 1/4" line for each axle, 3/16" line wherever you are pushing two axles. So, from the master you will have two 3/16" lines running until it breaks to go each individual brake.

Thanks nandress

That makes perfect sense. more volume through the big lines, and cuts off smaller to the individual wheels. The lines are not original and thought I would check to make sure they were not installed improperly.
