00 Brake Issues, what to do??

[SkylineNXS]

So i was wondering if anyone has or had the same issue as i do. With the truck in park and running, i can pump the brakes a couple times and get to a point where i cant push the pedal down any, but when its in drive i can never do this. In normal driving conditions, i can push all the way down on the brake pedal until it hits the floor. When braking, the pedal has a kind of nothing zone where it does nothing and then the braking starts, id say about half way down. I am assuming this is a master cylinder problem, but has anyone had this problem and fixed it? Only reason is that when u slam on the brakes, the stopping distance is huge, id never be able to avoid an accident with it like this. Thanks...

my truck you can push the pedal all the way to the floor too. but it stops good. I think its something to do with the abs. mine acts up when im in 4wd and bouncing around.

Yea thats what me an my dad were thinkin about, cause he had a bit of a run in with another guy and had to slam on the brakes, and he said the abs wasnt doing anything, which u would think it should since the brakes should theoretically be able to lock up the tires.

How many miles on the truck? what does the fluid look like? im sure it could stand a flush and fill with new fluid.

[SkylineNXS]

its around 81k, and the fluid looks good, but hasnt been changed since last time the brakes were done, which im gonna be doing soon anyway, so i figured it do anything else at the same time

The ABS should not affect pedal feel/performance until the wheel sensors detects a wheel lockup and activate the ABS pump/system. I would suspect a bad master cylinder or booster.

Sky have you had to replace the speed sensors on the front wheels. These trucks had a recall on them. the abs would kick in at 18 mph down to 10 mph during normal stops. they were either cleaned or replaced. i had both of mine replaced a few yrs ago.

[SkylineNXS]

The wheel sensors have not been replaced as far as i kno. My dad has owned the truck for its entire life so i will be sure to ask him. The truck has had this "issue" since we can remember, and i am finally addressing it is all. Thanks guys....

sky, find out about the speed sensors. and bleed the brakes. may have a air in them. all else fails try a new master cyl. hopefully u wont have to go that route. good luck man!

Thanks fx, i was kinda hopin i wouldnt have to do master either, haha. My dads in virginia and i can call him, so i gotta wait untill he gets back in order to find out about the sensors...looking at em i cant really tell if the have been touched or not...
