That's good info LazyK. Thanks for sharing. I once had a Master Cylinder fail and had the same symptoms. I wouldn't have thought of the RABS system.

 

Just pulled the spring out of my RABS module and the pedal seems to be holding. So from your description the module is bad. What happens if I just continue to drive it without the spring installed? I'm assuming my back brakes will lock up. Not sure how much pressure it takes now to lock them up.? It's not like I drive this truck long distances, its only used locally.

Thanks for the help btw

You can drive as it is now. On wet or loose surfaces under moderate braking you may get rear brake lockup. I drove my F250 for years with the spring removed with few problems, just means you no longer have RABS which a lot of guys bypass anyway.

 

That's cool, I live in Southern California so its not like I have to worry about driving in snow unless I go to the mt. and we don't get much rain. Think I'll leave it alone for now. Don't feel like bleeding brakes and I like the feel of the pedal and how it stops.
Thanks again.

Ya know there should be an area on the forum where you can go to get the fixes for problems such as this.
