TRUCK LOSING BRAKE PRESSURE AT RED LIGHTS

2004 Chevrolet Colorado • 130,000 miles

My 2004 Colorado, can stop on a dime with no problem. But if I am at a red light or in traffic, I will lose brake pressure. So I either have to push the pedal in further in intervals, or let off and re-apply. There is no visible leaks of fluid, the brakes have been bled, and the master cylinder has been checked. I keep rolling into traffic, and the only thing I hear from 2 shops is my foot most be falling off the pedal. Please help me.

Sounds like air in system or a bad master, Or a leaking line. It could be an abs problem as well. Power bleeding is the best for brake bleeding.
