2nd Gen Non-Engine/Transmission Loss of power-assist brakes

[pausma]

I have been experiencing an intermittent loss of power-assist in my 01 2500's brakes. I suspect it is a worn out hydro-boost pump because it usually happens as I'm idling to a stop. It feels as though the brake system is in an ABS event and in the worst scenarios I really need to stomp on the brake pedal. The thing I'm curious about is could a failed wheel speed ABS sensor cause the lack of power-assist brakes? My ABS and brake warning light occasionally come on but I haven't noticed any relation between that and when the brakes act up. Could temperature affect the problem? It usually gets better one everything is warmed up.

This would also apply to hydroboost brake systems. https://www.turbodieselregister.com...ering-assist-fix?highlight=low power steering

Is there a relation between the the wheel speed sensor/ABS and brake light and the loss of power assist? Or are those systems completely unrelated?

Based on the knowledge of my '97 they are unrelated. I suggest you go to www.techauthority.com and invest in a factory service manual. It will be the most used tool in your shop.
