Brakes make unusual noise when stopping

[fireman70]

If anyone has any advice heres my problem. When coming to a stop after picking up speed the brakes make a weird noise. Hard to explain what it sounds like. When I press the peddle it feels normal then it feels like it releives pressure and the peddle goes farther down but doesnt go straight to the floor, theres also you can feel a vibration in the peddle also. I've bled all break lines and new brakes are on the truck. It was doing this before i done new brakes and bled the lines. could this be something to do with the ABS system? or the booster?

First welcome Fireman70! Your post is a little vague. You lack what type of RBV: year, model, engine, 2wd or 4wd etc.... You feel it in the pedal? Does it sound like a squeal or a grinding noise? You put brakes on but did you put front & rear? How far into a brake job did you go? Replaced or machined the drums & rotors? Did you replace the hardware?

Sounds like a classic ABS speed sensor problem.

Take it into the dealership and get them to scan it for codes. They might need to test drive it while watching the live data from the speed sensors to see which one is dropping off.

It's usually one of the front 2 sensors.
