Tires, Brakes & Suspension / Re: Brake Help
« Last post by glhx on May 10, 2024, 08:58:17 AM » Mine isn’t leaking fluid. It’s pulling in air.
What I did was several things
First I used a pressure bleeder. This didn’t help
Then I bled them with help of a person…..the normal way. It didn’t help
Then I hooked 8’ of 3/16” tubing to the bleeder screw and ram it all the way up to the master cylinder to cycle the fluid. Like bench bleeding but on the whole car. I sealed the threads with Teflon tape for the bleed only. Then cracked the screw and left it open. 200 pumps later and it still pulled in air.
To rule out the Teflon tape being the problem. I drilled a bleed screw down the center so it could be tightened down all the way but still flow fluid. Still hooked to the 3/16 tubing to the master cylinder and cycling. 200+ pumps later it’s still pulling air.
So then I got a second person. Went back to the original bleed screw and hooked back up the 3/16 tubing back to the master cylinder.
I don’t see why the fluid needs to go into a bottle when it can just go back to the master cylinder.
Bled the natural way…..
3 pumps and crack the bleed screw.
This showed me.
For sure that somewhere in the drivers side back caliper or the lines in between are pulling in air.
It’s timed air.
I pump it up 3 times and crack the screw. No air.
Pump it again and crack the screw. Same amount of air every other time and it cycles like this.
3 times….no air……3 more times…..air…….3 more times…..no air
My next step is to take apart the caliper and look for putting in the seal area.
And remove the brake line and re seat it.
Other than that…….it has been a long expensive problem.
The whole system is all new. I’ve replace everything.
I will add that bleeding this way with the hose from caliper to the master cylinder. With this type of caliper will allow you to pump the Brakes as many times as you want with no mess and it will get all the air out of the system. If there is no leak.
I’m 100% sure I’m pulling air in the drivers side system.
I’m hoping you have better luck.
These are calipers from oreilly but they are cardone rebuilds
I have solid knowledge of the system. Especially how to set the e brake and how the caliper works internally.
I have some old calipers taken apart showing the whole thing.
I have a good idea which seal is leaking and im pretty sure it’s the e brake seal.
The yellow thing in the center is typically not a leak point. There is a large o ring in the piston itself that should seal all of that. It’s buried way down inside the piston ratcheting system.

Is your rear bumper cover still the rubber type? I noticed the 499735 strip installed. My 78 bumper cover was close to immaculate but had slight ripples or waves between each hole where riveted. So I've also sourced a couple of the strips to clamp it all down. Not original, don't care. The jacking brackets often had me thinking too. Originality aside, not going to ever use them and they are a tad clumsy otherwise. Could just as easily unbolt, leave off and panel over the cutouts if respraying covers. I'm sure others have done it but not really noticed. And cheaper to do nothing.

Tires, Brakes & Suspension / Re: Brake Help
« Last post by roadking77 on May 10, 2024, 04:36:49 AM »I am having the same issue actually. I have a 'mighty vac' hand pump that I used on the fronts and it worked like a charm. I got the rear caliper hooked up and started with the mighty vac last night and I pumped until I couldnt stand it any longer. After letting it sit a bit I found a leak where the main hard line attaches to the flex line that leads to the splitter on the rear. I have a very clean shop floor and saw a drop of fluid. I tightened that up and pumped some more but no luck. I figure I at least have fluid to that point in the system. I am going to get help today on the brake pedal and try it that way. If that doesnt work I am planning on going back over the system.
When the shop did my 77 the mechanic told me he could not get the rears bled and found out it was a bad master cylinder?
He swapped it out and solved the problem.

« Last post by glhx on May 10, 2024, 02:12:38 AM »I have this system and I have had a very hard time getting it bled. The fronts bleed fine.
The back passenger side as well.
The drivers side keeps pulling in air and I think it’s pulling it into the caliper from the parking brake system.
If you can get this bled. Please post and let me know what you did and where you got your parts from.
My whole system is all new. All the hoses, brake lines, calipers and master are new
