Chevelle updates

Wow looks great! Keep it up.You're giving me ideas.

Rainy Sunday morning here yesterday so I spent some time back on the Chevelle. Still waiting for the fuel pump - will be a couple more weeks I guess.

Last week I was able to get the rear brake cylinders assembled and installed. My plan for yesterday was to install a new rear flexible brake line and bleed the brakes. I bought an AC Delco line rather than a repop figuring I wouldn't have any issues - but guess what...the hole for the attaching bolt wasn't machined big enough. I should have known when I saw the Made in China on the box....

I hooked the old line back up and started to bleed the brakes, was able to get fluid to the back but for some reason I am not able to get fluid out of the front calipers........will need to diagnose that next. So it sits for a while longer now.

Might want to try bench bleeding your master cylinder, since you had it all apart and reconditioned.
All the parts turned out great!!

If you have the piston style proportioning valve, it may have tripped from pressurizing the rears and has cut off fluid to the front.

I think that may be my problem - I bench bled the master last night with no issues, but still no fluid to the front calipers. I stopped by a friends shop this morning on the way in and borrowed a tool to re-center the valve and will try that tonight.

Thanks

Ok. Good luck.

Re-centering tool won't work on my prop valve as the pressure switch does not appear to be removable from the valve while on the car. Getting fluid to the valve from the M/C but nothing out of the front port, so it has to be the valve being un-centered.......ugh. Tried compressed air into the front port multiple times to re-center it but no luck. Also tried tapping on the side with a hammer with no luck. Think I am going to have to remove the valve to try and disassemble it or send it out - but the rear brake line is not playing nice and does not want to come off, as it is the original to the car and I don't want to twist it. Soaking the sh*t out of it and letting it sit overnight. FUN!

Crack open a bleeder on the rear and you should be able to push the plunger.

I tried compressed air pushing back through the front port of the distribution block (I am using this term interchangeably with the proportioning valve - on my car I have a cast iron distribution block that is mounted on the frame under the master cylinder - unlike the 69-70's that have a brass one attached to the master cylinder) with no luck. I assume the plunger is pushed forward since there is fluid to the rears - so pushing air from the front should move it to the rear to allow fluid flow to the front? Interesting thing is that the compressed air comes back through the master cylinder but yet no flow the other way.............??? Are you saying to crack a rear bleeder to relieve some of the air pressure in hopes the plunger moves?

Appreciate all the comments and suggestions.
