Early Sportvan Brake Lines

Hello everyone,

When I got my 1966 Chevy Sportvan there were no brake lines at all, and I am not too sure how they originally ran them. Does anyone have pictures of the underside of their van on how they ran theres? Anything will be helpful. Thanks

I will be working on mine this saturday and will take pics if someone has not already posted some.

I also had another question. I have the original master cylinder in it now, how much work and money would it cost to put a 2 line cylinder in it/

What Don said:

Best modification that can be done to a 1st gen is a duel circuit master. If you use the corvette style 1.125" bore master with the "ddep hole" for manual brakes ans a couple 10 lb residual check valves you will have a good solid brake pedal . Providing you blead it all correctly.

Where can you get a decent priced cylinder like that?

Finally going to be doing this upgrade on my van this weekend. Im gonna make up some blocks for the sway bar. Don, are the little cut-outs on the blocks in the pictures above so you can turn a wrench inside there?
Im assuming you're bolting the block to the frame, then bolting the sway bar to the block with separate bolts?

Any other tips you have for this project? Thanks!

Shoulda used the search function earlier….answered my own question.

I suppose it would be just as easy to get longer bolts and go through the bracket and the block, since mine has tapped holes in the frame for the sway bar (?)

Don,thats great on the layout of all lengths for a dual set up.I was lookin,that single system has to go.When time will permit.
Also,your sq.tubing,looks like 2" 11ga..Is that about right,for the sway drop?

Don, would you be able to give me a breakdown of which length lines are used where?

Might be easier going with Braided Stainless if all the mounting and everything is gone already? More expensive though I guess.

This was great to see. Think I will get this rolling on the 66 also. I have a bunch of 2x2 11ga tubing scraps in the shop from my Van Lift build. Nice info Don. Thank you!

Don rocks.

If I am just upgrading my stock drum brakes to the dual line system, will I also need to add combination or pressure differential blocks?

Perfect! Thanks for the info. I may be giving you a call this weekend if I run into any unforeseen problems.
