Hello. I am new here and just recently picked up a 1999 Tahoe 4door LT. I have noticed the brakes are spongy and go down pretty far when stopping. Also when i start it up for the first time in the day and drive like 5-10 mph and press the brake it stops super quick...too quick. I was sitting at a red light with my foot on the brake and it started moving, and i have to press even farther on the pedal which i know is not right.... Anyway I took it to goodyear and they said I need a new ABS pump becuase its leaking fluid right onto the wheelwell, but its a really slow leak it seems like. They said its like a 700$ part and 400$ labor to fix which i dont have right now...I was wondering if anyone else knows much about these ABS Systems?? Thanks
