42 pickup brakes issue, difficult bleeding
I have a 42 pickup that i have restored the brake system. All new parts and attempting to bleed the system. I managed to get full fluid to 3 out of 4 wheels and then it returned to air. I have no leaks and wondering where the air is coming from. Thanks

Re: 42 pickup brakes issue, difficult bleeding
Bleeding early Ford brake systems is usually a challenge. The location of the master cylinder in relation to the wheel cylinders is the cause. Using the "pump and hold" method can waste a lot of fluid. If you can get the vehicle to a brake shop with a power bleeder, that is a good idea. There are some DIY bleeders available as well. At our shop, our old bleeder uses a tank with a bladder that is powered with compressed air, making the job easy.

Years ago, I'd made an adapter for the power bleeder to accommodate the Ford master. One of those little things that I look back on and wonder how I'd managed without it for so many years.

Re: 42 pickup brakes issue, difficult bleeding
I've got Speed Bleeders at all 4 corners of my truck. Takes under 10 minutes to bleed brakes. I think all the Ford wheel cylinders were 3/8-24 on the bleed fittings, so that would be the size.

I, too, am sold on "Speed-Bleeders". Life has been better since I found them.

Re: 42 pickup brakes issue, difficult bleeding
I just purchased a vacuum bleeder. Hopefully this will solve my problem Thanks

Re: 42 pickup brakes issue, difficult bleeding
I have used a vacuum bleeder with good success. If you use too high a "suck" it will draw air in past the bleed nipple threads and possibly the wheel cylinder seals. Low vac and slow gets the job done.
