Fresh out of the sand and packaged ready to go, should bring the project on another tiny bit,



Brian,

WOW,,too cool,perfect addition

Cam end plates? You'll have to show us how you make something like this some day.

You guys are just Masters of the art. Again, just WOW.

This weekend got off to a really slow start. Saturday was Valentines....didn't dare go into the shop even after Lana said it was fine...I'm sure it was a test to see if I want to spent the day with her of my Italian mistress.

Today was to be car day but one of the kids wasn't feeling well so I waited until Lana was up and BAM! power went out, I finally got to the shop at 3

The exhaust parts aren't here yet and I forgot I wanted to shim the engine mounts so I tore into the brakes.

Pedal assembly out
Old Mouse nest cleaned out
Booster removed
fiat van master cylinder which was a bolt-on if I left the boost adapted.

I THINK this mast is big enough to make make the new calipers work and small enough to correct the pedal ratio for no booster. I'll try it and see what I have.

Next up is figuring out what to do for a clutch master and getting parts on order.

The thought that crossed my might today is I think what I'm looking forward to the most is washing 8 years of dust off it....it just looks awful

So Mark , the plan is to loose the brake booster completely ? As per race car ? This is because you don't have enough vacuum ?

yes, yes, and yes.

A stock 308 QV idles with 18-20" vacuum and boosters typically need about 15+ to operate properly so all is well. I expect about 8-10" vacuum at idle so that's not going to work.

On deceleration I'll pull that much vacuum so I could charge the system and maybe add a reservoir and end up with a system that gives me 2-3 brake taps at the redlight or in the parking lot before the power fails...so that would just suck.

I could add an electric vacuum pump to the system and it would work but comes with the sound of s vacuum pump running plus weight and if the pump or the wires or the pressure switch or the relay fails so do the brakes so it's not ideal.

Then I remembered my 1965 corvette with big 4 wheel disc brakes and no power brakes. When I first drove it I knew it was manual brakes so I stomped on the brake pedal...and nearly went through the windshield. The brakes in that car were GREAT! I've done a bunch or reading recently and universally when the people with big cams and no vacuum convert to manual brakes they are happy and wonder why they ever even tried messing with power brakes because they have exactly the same experience I had with my '65 vette....manual brakes work great on a 3200lb car.

I may need to play with the pedal ratio a bit...I'm not sure. I just went up to a 1" bore master to get enough volume for the calipers....maybe. 1 1/8" bore is the standard answer for 4 wheel discs but the stock ferrari master is 7/8" I think but a couple 308 owners have reported switching to big calipers and the fiat 1" master with no problems so I think it has enough volume...but they were still running the booster so I'm not sure I'll have the ration right. We'll see.

The housing got a quick clean-up and the adapter a radius on the exposed face and looks nice.

The clutch master I'm not exactly sure what I want to do.....so I ordered something and I'll see what I can do with it when it gets here. The throw out bearing says .700 or .750 bore, since this is a street car I went with .700 to get better modulation and hopefully its as good as i had with the mechanical setup.

Shim the motor mounts 1/4" so the engine won't bounce on the frame - Check.
