I have a 2003 Yukon denali. I have replaced front hub assemblies on both sides. both front calipers, hoses, rotors and pads. and also drivers side rear caliper. also replaced master cylinder. manually and electronically bled the brake system 10 or more times. if stitting at a traffic light after about 10 seconds the brake pedal falls to the floor slowly and the truck starts moving forward. what can cause this?
Ist dies eine gute Frage?

A “soft” brake pedal that goes all the way to the floor can be caused by a number of reasons.

I agree with [ Mayer ]
I know this is an old post, but just in case anyone looks at it.
Always check for leaks first. You must check brake fluid level is not dropping. Only Then look for the other things like the Failing master cylinder, (internal seal failure). In my case I already replaced the master brake cylinder, so think I have a faulty ABS module itself ( faulty valves ), intermittently causing the pedal to go to the floor. It can also be caused by sticking calliper's. If a brake pad is moving away from the disk, then the pedal must travel further before the brakes go on. Also check your hand brake adjustment is correct.
Thanks just starting to have this problem
