Thru-frame fittings

I am having trouble getting brakes on the front of my '34 Ford. I have bled and bled and bled the system, including bench bleeding the master cylinder.

Could the Billet Specialties thru-frame fittings be holding air? If so how do you bleed the fittings?

The bleeder valve must be below the master cylinder to correctly bleed the brakes. You may have to remove the calipers (or backing plates and wheel cylinder assembly) from the spindles and place them on the ground to get them below the master cylinder. This is for a system where the master cylinder is mounted below the floorboards. Also be sure that the bleeder valve is facing up when bleeding.

The thru the frame fitting should not cause a problem.

What calipers do you have? I have Wilwood calipers and you must bleed both sides of each caliper, starting with the caliper furthest from the master cylinder.

My master cylinder is mounted on the firewall and the bleeders are on the top of the calipers.

I am using GM calipers, wish I had Wilwood.

I cannot get the brakes to work properly. I bled the brakes several times and with just one caliper hooked up I barely get brake pedal. I am using a 1 1/8" master cylinder. It appears I get a good volume with each stroke of the MC. This makes me think that the Thru-frame fittings are traping air. As much as I have bled the brakes I do not know where the air could be trapped.

CAR FOR SALE CHEAP, no brakes HAHA

Tried to post a reply just now, seems like it did not "take". I'll try again, sorry if this is duplicate.

I read somebody else had a similar problem and it turns out they had the calipers reversed, left one on the right side and the right one on the left side. The break bleeders were therefore higher than the fluid in the caliper, so the air wanted to go up above the bleeder. When they reversed the calipers, right on the right side and visa versa, the problem stopped and the breaks worked after bleeding.

Hope this helps and sorry if it was the first thing you thought of.
