Maintenance / Disc Brake Proportioning Valve

« on: August 27, 2009, 10:49:15 PM »

My '69 Z28 has the factory front disc and rear drum brakes. The front disc brakes used a proportioning valve which has a boot/button on the back side of the valve. It's my understanding that this a "pressure button" which allows you to basically bypass the function of the proportioning valve to allow for bleeding of the front calipers.

The button on the valve that was on the car when I bought it didn't seem to work - when I pressed on the boot I didn't not feel any button release or movement. I was not able to bleed the front calipers.

So - I bought a new "original type" proportioning valve with the boot/button. Before installing it I tested the button to see if I could feel it release - it was hard as a rock with no movement. I presumed at this point that the valve needed some pressure in the system for the button to operate. So I installed it. Guess what - I still am not able to feel in movement in the boot/button when I press it. I am still not able to bleed the front calipers.

Does anyone know how the boot/button on this original type proportioning valve is to supposed to operate? What am I supposed to do that will give me the ability to bleed the front calipers?

Your wisdom is appreciated.

Maintenance / Brakes Not Working After Brake Line Replacement - 69 Camaro

« on: August 22, 2009, 02:43:22 PM »

I replaced the brakes lines on my 69 Z28 (front disc/rear drum) during a restoration of my undercarriage. I did not remove the master cylinder or power booster nor did I drain the fluid from the master cylinder. I simply removed the old lines and installed new lines. The lines were bled in the typical fashion starting with the rear brakes and working to the front brakes. After extensive bleeding - the front calipers aren't moving at all when I depress the brake pedal. The pedal bottoms out without any resistance to speak of.

Any Suggestions?

Maintenance / Vacuum Reading - 302 Engine

« on: June 19, 2009, 10:08:47 PM »

I have a 69 Z28 with the original 302 engine. The vacuum reading is 12 to 13". I am unsure if it has the original cam.

A couple of questions for anyone who may have the answers:

(1) What should the vacuum reading be for a factory stock 302 engine with no additional options other than the factory installed items (front disc brakes, no A/C)?

(2) How (if at all) does the vacuum affect the funtioning of the cowl induction system (mine does not appear to be working)?
