I need some help with the brakes on my '96 Tahoe. I think the brake booster is on its way out (very soon), but I'm not 100% sure. The pedal has always been very mushy, and the truck is definitely underbraked. Recently, I noticed that when I depressed the brake, I hear a very loud woosh, a vacuum type sound. I thought at first that I had a vacuum leak, and that may still be it. The sound was always there, but not as loud. If I pump the brakes on my truck two times or so, the mushy pedal goes away. However, recently (the past two days), the pedals has been much more firm at times, too firm infact. When the brakes are pumped it becomes VERY difficult to depress the brake, the pedal gets that firm. Today in traffic, I was on and off the brakes, I came to a stop light and began to roll forward, when I tried to stop, I had to really push the pedal, and it only moved about 1" down, but the truck did stop. I had to hold some pressure on the pedal as well. When the light turned green, I let off the brake and stepped on the gas lightly, the truck felt as if it were in neutral, it began to roll forward, but very slowly, and then the brakes released I guess, and the truck started to move, after it slightly jumped forward.
What do you guys think is causing this?
Bad brake booster?
Pressure in the lines?
Vacuum leak?
It cannot be anything with the ABS, because it is disabled.
I'm going to go outside now and try to figure it out, but I need to get this fixed asap, as this is my only mode of transportation.
Thanks for the help,
