Hard Brake-line routing details

Post by sdb8100 »

I've checked the topic of brake line routing and there are pics on this site for high level understanding. However, the detail of how the OEM hard lines go to/from the firewall components [distribution block & master cylinder] to the front RH and front LH wheel flex line isn't clear. Anyone have some detail shots of that? Also details around the clips/brackets that hold down the engine bay hydraulic lines would be valuable.

This might help a bit-- this is a stock 69 2000:

We threw all that away and redid it to look like this:

I've seen these, thanks. These are a great overview for sure. The routing under the master cylinders and along the rail of LH side gets hidden. Similar with RH side rail under the distribution block.

So from the distribution block, would you run the right side line forward and then across the radiator support or the along the front frame to keep the line totally hidden? Maybe put the line splitter inside the left wheel well?

From our latest build thread-- more ideas here:

Before we could put the body on the frame, the brake and clutch systems needed to be built as they would be difficult to do after the body was on the car. As many of you know, we love rebuilding the brake lines to make them as simple as possible, and this car had another evolution on that process.

The Datsun 240Z 7/8" master cylinder was mounted to the firewall, as well as the standard clutch master cylinder, and new lines were built-- I like to get the out of the engine compartment to clean up the look:

Image

These poke thru the inner fender, and start their transition, either forward for the front brake lines, or to the rear for the rear-- the clutch line will follow the front brake, but instead of going across the firewall, will go around the front:

Image

Since the brake lines are outside of the engine compartment, they are armored with stainless steel brake line spring.

And across the front:

Image

And back through to the other side-- clean and simple, and really cleans up the firewall.

Beautiful work! Thanks Michael! Kinda what I thought you would do for routing line in front. Now, any suggestions on a duel master cylinder on a 66 without to duel cyl pocket? Smaller air filter with duel MC? Aftermarket MC?

With the early, flat firewall, you would need to go with a dual Tilton master cylinder setup--- something like this:

Bringing this hard line thread back...I got the routing of the hard lines in the engine bay. fuel, clutch, oil, brakes pretty well understood and routed thanks to this site.

The detail that I'm missing is clutch hard line to slave cylinder soft line...I have a braided slave cylinder line I got from one of our vendors, but it doesn't seem to match the connection to the clutch hard line.

MY INITIAL THOUGHTS:
-I am missing a coupling piece
-I got the wrong slave cyl. soft line sent to me or there are multiple variations I wasn't aware of.
-other?


Can someone post a close up picture of the slave soft to clutch hardline installed and also uninstalled [the two ends]?
