I’m not sure to be honest. I think so though. Thanks!

And yea it does look good when it’s clean but man, it’s a pain to keep clean. And to keep from scratching!

Nice! I was out in mine as well! Did you have the louvers on the last time I saw it? The car looks mean!

Number Crunching / 400 casting code

« Last post by 81Resto on April 30, 2024, 04:14:34 PM »

I have been searching out a Pontiac 400 block.  I had a couple of near misses, responses saying it was just sold.  A new one popped up and talking to the seller, he gave me a casting code of 039962 and y4.
I know y4 is an engine code but can't seem to find out what the other number means.  I looked on some websites thinking he sent me a wrong number, it doesn't match what I can find for heads, intake manifold,
exhaust manifolds... For the hell of it I put it in google and the AI part of the search said it is a sbc.  So I found some other websites for chevy and cannot find the number there either.  At this point
I am just curious.  Also looking to avoid the 500557 blocks based on advice from some books I bought about building a Pontiac engine.

Tires, Brakes & Suspension / Re: Brake pedal sticking to the floor with delayed release.

« Last post by glhx on April 30, 2024, 12:59:12 PM »

I replaced the master cylinder with a new one and bench bled it.
The master cylinder problem is solved and the pedal not returning is solved.

However…….after fixing this. The pedal was back to very soft. It had been like this for a long time now. Long enough to not drive the car for a while.

I replaced everything. Power booster, lines, proportion valve…..calipers all 4 corners.

The pedal was still soft.

I adjusted the parking brake for the rear disc to 1/16” of an inch to activate. You pull it 1/16th and it grabs. I think 1/8th could be ok but I don’t know. I saw where 1/16” was where it should be.

Either way. The parking bakes are adjusted well and I have a very good understanding on how to do that.

So……I still have this soft pedal. I bleed the brakes over and over and over again. The fronts bleed fine. Quickly and done.

The rear passenger  side bleeds fine. Takes a while…..but bleeds fine. No air whatsoever. Not even the smallest bubble.

The drivers side rear however. I bleed it and over and over again small puffs of air keep coming out.
So

I got some Teflon tape and wrapped the bleeder screw very thick so it would seal while being open and not draw air into the threads. I then got some 3/16 clear vinyl tubing and ran the tubes from the open bleeders all the way to the master cylinder.
I did this to both back calipers.

The passenger side……no bubbles.


The  drivers side however…….would not stop pulling air. Pump after pump…..probably 200-300 pumps of circulating fluid. It kept pulling big 1” long bubbles of air over a timed sequence.
As soon as the air was pumped back into the master cylinder. Another 1” of air would come out the tube from the caliper.

So what this means is that my drivers side caliper WONT LEAK FLUID. But will pull in air and not allow me to bleed the system.

With both calipers hooked up at the same time in the back to the 3/16” tubing. It’s only the drivers side that pulls air. I checked all connections and they are tight.
This is a new caliper from O’Reilly.

I have caliper cores so I know what the system looks like and exactly how it works.
I guess…….its pulling in air from one of the 2 seals?

There is a check valve on front of the piston but no fluid is coming out of it. Which I don’t think fluid is ever supposed to come out of it. I think it’s meant to get rid of air behind the piston and not let any back in. I will add that when I took the check valve off. It had some rust under that seal.  Not much but some.

So……I have warrantied out the caliper hoping the new caliper will be sealed.

What do you guys think is acceptable for for inches of travel for an e brake adjustment?
1/16”
1/8th”

And

Why or how do you think that one side is not leaking fluid but is pulling air.

Keep in mind……every part of the system is new. Hoses…..brake lines.

All of it……

It’s just this one caliper and it has cost me about 15 hours to diagnose.

I will add that putting in that clear vinyl tubing and pressing the brake pedal over and over again has helped a lot to figure the problem out and instead of using my pressure bleeder in this car. I will be using this method. As it cycled the fluid over and over until the air was gone
At least in 3 calipers.

If I can get that drivers side to stop pulling air. The system will work to 100% again.

Good for you and your car. It looks sharp. Black sure looks good when it’s spotless!

Looking good! I replaced the ones on my 79 TA. Word of caution, on my replacements the seat belt bolts weren't in the exact same spot. I had to make new mounting locations.
