I tried for 2 hours today, with the wife getting lots of leg exercise, to bleed the brake system in my 68 Cuda. I had Wilwood rear discs put on a Ford 9 inch. I cannot seem to get the air out of the system. I went through a 32 ounce container of brake fluid filling the master cylinder and still no pedal. I have checked all of the fittings and they are all tight. Any suggestions?

I always used the 1 man bleeder from the parts store with good luck. Are you following the directions from wilwood? Not being a smart alleck but I had to read the steps when I did mine. Since they have 4 bleeders on the calipers.

you ARE making sure the master cylinder never runs dry before adding more fluid right???

Yes I have read and understand the procedures from Wilwood. And yes I am making sure the master cylinder is full and does not go empty. But doing all of that has netted zero results. That is what lead me to check all of the fittings to ensure they are tight. Air has to be getting into the system from somewhere is all I can figure.

don't know the wiliwood set up, but 2 things to look at.
Are the bleeders on top? A lot of people swap calipers and don't realize it for some reason.

2 even if they are on top, are they at the very top?
One of the after market setups could not be bled mounted. You had to take them off to get the bleeder at the top.

Is the master cylinder new? I had one go bad out of the box. Try opening all the bleeders and try gravity bleeding. Other than that re bench bleed the master and move on again.

I would bleed the MC by itself then put a brass plug in one side of the MC & hookup the other half & bleed it out then hook up the other half. A problem area that has snagged me in the past is not having the bleeder screws tightened enough & air being drawn back in. My procedure,crack bleeder screw,helper pushes pedal down 7/8 & hold, I tighten screw,have helper let up pedal.

Thanks for the replies guys. I will start again at the master cylinder and try the brass plug idea. The master cylinder is the one that came on the car when I bought it. It has the large fittings on it so finding a bleeder kit was hard. Maybe I will just make up some lines to bleed it with. Again thanks.

Get some speed bleeders, you'll never go back once you try them. I have the Wilwood caliper bleeder size if you need.

That said, the one man bleeders are the same thing except you can't get any air past the bleed screw with the speed bleeders.

Bad Boy you might grab 2 brass plugs at your parts house & cap off the MC & if it's good (& bled out) the pedal will be rock hard & virtually no travel, then hookup one half of the system & get it bled. This helps narrow down where the problem is. You might put a block of wood of the proper thickness under the pedal so your helper wont push the cups past their normal wear area which might hasten their demise. A small detail but I get anal about these things & it lets your helper easily keep the pedal motionless until you close the bleeder.

Just make some that loop into the MC bowls and you can bleed it on the car. Keep pumping till there are no bubbles and then a few more for Murphy.
