Spongy Brakes on you Dad’s Chevy Truck

[Mechmann]

Hi Eric,

Your Dad’s truck has a combination brake valve (a proportioning valve,a rear wheel pressure hold-off metering valve, and a failure mode pressure switch). You did not mention it during the bleeding process at the rear wheels, but the little rubber button on the end of the unit (metering valve) must be held in using a makeshift tool or by having an assistant hold it in. Otherwise, it is my understanding that the rear brakes will not bleed properly. Hope this helps.

Great step-by-step “how-to” video.
