Second gen camaro brakes will not bleed

[charlie79z28]

I installed new everything on my 79 z28--properly bench bled MC, 4 wheel disc prop valve, lines, hoses, wilwood 6 piston front kit, 4 piston rear kit. I went to bleed the system and I can't get fluid at any of the bleeder valves. I tried the pump method with no success, and it has been unsuccessfully gravity bleeding for about 3 or 4 hours. Pedal just goes to the floor, master cylinder is full. Any help would be appreciated, thanks!

Okay... Might be a it basic but do you have the correct length rod to reach the master cylinder? There are different rod lengths depending on which master and booster you have.

Granted, it should still gravity bleed but I would check to make certain the piston in the master cylinder is fully moving when you press the brake pedal.

[charlie79z28]

Pretty sure I used the right rod, I remember it made a point of mentioning that in the install instructions. I had the short pocket, so I used the shorter rod

Did you bench bleed the MC? If so, by what method, recirculation or plugged?

I had a terrible time with mine. I had bench bled it, tried gravity bleeding, pumping, and even a vacuum bleeder. If you replaced all those components I think it can get air bound in the section of line under the drivers frame, and you proportioning valve can stick to one side if you try to bleed the fronts first. I borrowed a pressure bleeder from work and finally got mine to work. The pressure bleeder has a cap that goes on top of the master and slightly adds pressurized fluid to the system. I cracked that right rear bleeder and after about a quart of fluid there was a loud hiss and out came a bunch of air. Good luck, I know how frustrating this can be.

If you close all the bleeders, pump the pedal numerous times...does pressure build up? If you bled the MC, you know that works. How old is the booster?

[charlie79z28]

All parts are new. Pressure does not build up after pumping. I could always borrow my school's pressure bleeder and see if that works

might sound like a basic question but which way are the bleeders pointing?
are they pointing up or down?

This sounds similar to what happened to a friend of mine and he spent ages trying to bleed his brakes on his 68 Firebird until I told him that he had installed the left caliper on the right side and vice versa.

Once corrected, the system bled straight up with no issues. LoL

They're wilwood calipers so they got four bleeders, but even still I installed them according the arrows on the calipers

[Smoker03]

So are you bleeding from the top bleeders or the bottom.

[charlie79z28]

I've been bleeding from the top, like on oem style calipers
