Ok now I have a new to me IDI with a problem.
The truck is a 1992 1/2 with serpintine belt 5 speed.
The problem is the ABS light keeps coming on and lately when I first drive the truck the brake pedal feels as if there is no boost until I go about 10 miles.
I have checked the Vacuum. It reads 15 at the pump. But as soon as the brakes are aplied the vacuum goes to 11 or less.
I have blocked off the brake line it does not bring up the vacuum.
I am begining to think the pump is bad.
HELP this is my daily driver
