Okay so as many of y'all know I've been having an ongoing problem with my brake system. This spans back a handful of years. Come to find out your supposed to bleed the ABS box after the brake job because the system had went dry and changed the master cylinder so air got in the ABS box. Month or two ago we put hey tech 2 scanner on the truck and did the auto bleed feature for the ABS. After performing the bleed I noticed that the bleeder pin on the ABS box that faces the engine was missing. I know it was there before we did it. I will post pictures so you know what I'm talking about. Evidently there is only a lower bleeder facing the engine if you have drum brakes. Anyhow as I said the lower pin disappeared I don't know if it fell out somehow or if it got sucked into the box somehow.. so I got another ABS box from the junkyard this week. I checked and made sure all the pins were present Honda upper bleeder facing the fender the lower one facing the engine and both of the ones under the brake lines. I installed the ABS box today. I gravity bled all the lines. We hooked up then tech 2 scanner, ran the auto bleed feature. And guess what.. the same pin on The New abs box disappeared. WTF.!!! This one has me completely baffled.
First pic is the upper bleeder showing what pin I'm talking about. Bottom one should look same and did until we performed Auto bleed second pic is lower bleeder after auto bleed
