Hi Guys,

I replaced 2 front calipers and 2 rear wheel cylinders. When I went to bleed the system I thought all was well when I didn't get any more bubbles coming from the bleeder valves. When I started the truck up to take back the cores for the calipers the brake pedal went all the way to the floor...no brakes. I crawled back under the truck and started to bleed the rears again but I didn't get any fluid coming out and pressure could not be built up enough to produce any. The front calipers bleed ok but I still had no brake pedal pressure. I went out and picked up a one man brake bleeder from Craftsman but couldn't get the pressure up enough to draw fluid from the cylinders without sucking air in around the bleeder threads. How did I get so much air in the system??

I'm heading out to get the components to build my own power bleeder as listed in this site and I'll keep you up on the results. I just wanted to run this by the "experts" to see if I missed anything. And yes, I did maintain adequate fluid in the reservoir to keep from sucking air from the master cylinder :>)
