Brake Question

I have a 98 GMC 3/4 Ton 4X4 Ext cab short bed pickup, I have a question about the brakes, I got the truck about a year ago and when i pushed on the brake pedal the truck would stop fine, but i could keep pushing the pedal and it would go all the way to the floor. when i asked the used car dealer i got it from they said it was working fine, because it stopped with no problem.

Last week it developed a bad antifreeze leak from the intake manifold and since i have an extended warranty i took it to the dealer and had them fix the leak and the brakes. after replacing the front pads, the mechanic said it was fixed, i picked it up and took it back the next day because i could still push the brake pedal all the way to the floor. after going for a test ride with he mechanic he told me that from late 97 to early 98, GMC used a different 2 stage ABS system and that was normal for those models and that my brakes are working properly and that is normal so that no matter what the brakes cannot be locked up.

here is the question, has anyone had this problem or heard of this, i have never seen any vehicle that i could push the pedal all the way to the floor. i really think this guy is trying to pull one over on me, but you never can tell sometimes. thanks in advance

Re: Brake Question

the pedal shouldn't go down to the floor. you might have a leak in your system; your master cylinder might not be working correctly. how's your fluid level?

Re: Brake Question

there isnt any leak and the fluid level is normal. I think it may be the master cylinder also, but the tech at the dealer said it was normal for late 97s to early 98s.
