Title: '68 Z28 Need pic - prop valve/splitter mounting and line layout
Post by: barsteel on August 17, 2015, 08:12:48 PM

Hello -

When Jerry looked at my '68 Z28, he remarked that I was missing the brackets that mounted the proportioning valve and line splitter block to the power brake booster.  Right now, they're just hanging in place by the brake lines.  I've since ordered the correct brackets from Rick's Camaros, but I'd like to see a pic of how they're supposed to be set up.

Also, I'd like to make sure that my lines are run correctly.  I've attached a pic of the setup I have now, although I already have the correct MC on order.

Forgive my ignorance, but on every brake system I've ever set up, I had the line for the rear brakes (the smaller, rear reservoir) feeding into the proportioning valve;  As I understand the valve's purpose, it is to restrict brake fluid flow the to rear brakes so as to prevent them from locking up before the front brakes.  Please excuse my ignorance if I'm wrong.

As the system is set up now, the front brake lines (large front reservoir) feed into the proportioning valve.  Is that correct?

Thanks in advance...

Chris

Here is a picture of our system on our 68Z. Might want to consider re-doing a few things (master cylinder) since your making some corrections. When was your 68Z built?

Here's a CRG site article that explains the correct description and function of the various brake system valves:
