Brakes too close too floor!!!

[kewlgye]

Okay guys,
This has been talked about before. I've got a 98' z71 k1500. The brake pedal travels way too close to the floor for comfort, sometimes all the way. I've tried everything most can think of. On top of bleeding the system, the right way, about 15 times, I've replaced the master cylinder, front brake lines, pads, and rotors. I took it to a shop and had them bleed them, but no luck. They did however have a scan computer for the ABS system. They ran a bunch of tests on that $1000.00 ABS module, and everything works perfect, including all of the motors in it. The last thing the guy did, was run a self bleed with that scan/computer tool. After he did that, I got a very little bit of my pedal back.
I then went to the dealer and talked to the head tech. He said I had air stuck inside of my ABS brake module, and the only way to bleed it is for them to hook the truck up to their computer, and bleed it a certain way. He said there are a bunch of motors and valves in that module that have to be in a certain position in order for it to be bled.

Do you think that sounds right??? Any other ideas????

yah, i kinda get the same thing. new pads, one new caliper (drivers), replaced rear shoes, bled lines....a lot, watching the master cyl...had a mech adjust brakes for me cause i thought i mnusta done sumthin wrong...but i still get more pedal travel than i would like and i get the abs kicking in very easily...seems touchy....in places that you wouldn't expect abs to kick in.... wtf????

a coupla days ago replaced the badly worn out rear brakes and found that the wheel cylinders were pooched. couldn't take care of it then (i did the repair after my 12 hour shift at work....NAPA was already closed....), had them replaced the next day at a shop.....pedal travel was the best its ever been! and the ABS doesn't act up like it used to.....
so have your wheel cylinders checked? notice any uneven, excessive shoe wear?? not sure if that's any indication but it's a thought....i'm learnin' as i'm going....
