so i working on multiple issues with my truck have different posts.. but i waiting for parts for the rear brakes.
and i had to take both calipers for the front to parts store so the master cylinder drained out.. reason i had to take it.. the replacement ones i got were wrong size. i guess the company that recores the old ones stuck the wrong calipers in for a1500 2000 truck or ould been they retapped the brake line hole bigger so the bolt cant go through the rubber line square... or was told in 99 00 dodge had issues with brakes making there own and getting from other brands like Gm so there are several listings

but so i wasnt able to stop it so it leaked out.. and i got the proper brakes after 3 calipers later.. different ones
i bleed it normally did the pass side front then drivers. but brakes still went to the floor and no air.. but i guess there is air in the master cylinder.. so instead of me taking it off and on a bench i just gonna get a kit or chop off parts truck and run 2 fittings and the line into the master cylinder and pump it with my foot like 20 times so i get the air out

but my question is there is 2 modules one as a stiker and a rubber nipple with FB on it i think now yellow sticker.. around the rubber .. and then goes into the 2nd module... are these both ABS? is one ABS other is something else.. what does the rubber cap do. and do you have to bleed the ABS too a i remmember someone told me on gm car you need special GM Tech tool to cycle the brake to bleed it..

so not sure what the procedure is. i havent checked the fsm annd i ordered 2 new rear cylinders.. but i figured id ask here if there is procedure.. but ill be reading the fsm later tonight

 

There is air trapped in the ABS valve. It needs to be activated to get the air out. Next ti me push the pedal half way in and block it. Then the fluid won't run through.
