Maintenance / Re: Disc Brake Proportioning Valve

« on: August 29, 2009, 07:57:31 PM »

Thanks John,

Unfortunately - the button will not depress on my old one or on my new one.

I am using a vacuum system attached to a compressor (similar to a mytivac). It pulls some fluid through but not much. That's why I was trying to use the release button which is supposedly what would allow the line to open up for bleeding.

Any thoughts on why the button is not operating correctly?  Do I need pressure in the rear lines for the button to work?

Also - I have heard the brake components called by different names.

Like you - I thought the valve attached to the power booster was called the meter or hold off valve. The company I bought it from calls it the proportioning valve.

I always thought the the proportioning valve was the one located directy under the driver's seat. But they call this the "hold off" valve.

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?

Originality / Re: 69 Z28 Grille Emblem

« on: July 14, 2009, 01:07:43 AM »

Here's the issue -

I have an original grille emblem and an NOS grille emblem.  Neither have any type of stamping on the back.

There's a guy on eBay who has a grille emblem listed as NOS that has the original part number stamped on the back. What's make me even more suspect is that he says it came to him in a GM box but the GM logo had been cut off.

Thoughts?

Originality / Upper Control Arm Bushings 69 Z28

« on: June 25, 2009, 11:29:55 PM »

I have located someone with what is supposed to be an original set that are in an original GM box with the correct part number of 3711826 on the box. However, the mold mark of the bushings states "Clevite Silentbloc 62659". Is anyone aware or know where to confirm if Clevite manufactured any of these bushings for 1969 camaros.

To ensure correctness of originality - how much of the underside of a cowl induction hood for a 1969 Z28 should be painted the same as the body color?
