1970 L/78 Nova brake valve setup question

[nuch_ss396]

OK Tom,

Let-er rip.

That's the general setup, but something doesn't look quite right. I'm going from memory here, but I believe there should be a plated steel bracket that holds the proportioning valve to the booster stud. I'm not sure how the one in the pic is attached. Also, make sure you use a m/c with dual bleeders, painted black.

The bracket is there is the pic.but not seen at that angle.I have the M/C with the dual bleeder,But painted black?

[YENKO DEUCE REGISTRY]

Black.

Pictures below of Jack Seymours unmolested, survivor 70 Z-28 with SAME parts you are refering to. Also pic of Dale R's ORIGINAL owner 70 L-34 Camaro showing black M.C.
M.C. lid should also be Yellow Zinc and Hold Down bail was natural steel (but most restorers paint with "natural" stainless steel paint)

L-shaped bracket swedged to brass valve should be Yellow Zinc DiChromate plated, as well as curved shaped bracket supporting Unpainted Cast Iron prop valve.
All the special locking nuts securing M.C. to booster and Booster to Firewall are Clear Zinc (silver) plated.

What is a good paint to use (spray bomb) for the Black M/C.? Thanks

[JRSully]

Also, what is the generally accepted practice of preserving a freshly yellow zinc coated booster.? clear it.? boeshield it.? nothing .? Thanks again

[L78steve]

The only paint that will hold up to the brake fluid is POR 15.And for the booster I just keep it wiped down with Super Lube.

[WILMASBOYL78]

Try turning it around and using silicone brake fluid...then you don't risk damaging paint or plating...we use it on all the restored cars...

Some semi black spray bomb choices are KRYLON 1613, RUSTOLEUM 7777, etc etc.........

I would think any of the GOOD Rust Inhibiting sprays on Yellow Zinc.........used consistently would help the plating survive........(I am NOT a fan of WD-40, versus BoeShield, Fluid Film, etc)
