This is what I use...and it works well...

The only thing is you need two people...one to keep the fluid full in the master cylinder and one to hold the hose at the brake caliper.

I have never found an adapter cap for pressure bleeding either the Reliable or the UFP....

Amazon amongst others carry them at a reasonable price.

Motive does have an adapter for their power bleeder, it's Part Number 1130 on their website. I have one and it works great.

Thanks for the info. I also have a Motive power bleeder and was wondering how I could use it on the trailer brakes!

TKS Jerry......... How does part #1130 fit and seal on a internally threaded master cylinder? I looked on the motive web site an they have a couple of internal threaded adapters (1 5/8 and 1 3/16 at the threads ) my 08 trailor measures 2 inches.

Sorry, should have been more specific. The Motive adapter is for a UFP master cylinder. It has a large rubber cork or stopper on the end that press fits against the opening in the top of the master cylinder. It's held in place by chains and hooks, the same as most of the Motive adapters. I don't have any of their screw in adapters, but do have a push on and turn type adapter for a brake master cylinder in a car. I've also made my own adapters using a master cylinder fill cap, and some 1/4" NPT brass fittings. I've used a Mitey Vac before as well, and the Motive is so much better to use. You can also use it "dry" to flush out brake lines, or to pressurize a full master cylinder.

i used the motive UFP adapter (rubber cork shaped head) for my trailer rehab several months ago. worked great. fill it up and pump it up and then ignore it while you bleed the brakes. i used the motive on my wifes ford with the screw on adapter. worked great for that car (expedition) as well.

I used this harbor freight kit. http://www.harborfreight.com/brake-fluid-bleeder-92924.html

very easy. If you dont have an air compressor, the bottle can be used with a mityvac system to act as a resivoir so someone does not have to stand over the master cylinder refilling.

If a person is proactive enough to be doing it on a trailer, it has probably already been done on their truck. If not, its worth the 45 min to do it on the truck too.
I just did a system flush on my 2008 gmc, wow bad smelling and funky dirty!
