I've been getting some pulsating in the pedal when im at slower speeds, i just had new rotors and pads installed, i thought that would fix it, i dont know what to do now, they work great until about 15 mph then it gets bad. any information will help, thanks a lot

 

Year and model please. But I would say wheel bearings or just a little out of round tire. My bearings are bad and in need of replacement but the garage I going to use for the day well the dude is out of town lol so have to wait a week. I have the same felling coming thru while not bad but its deffently a cause considering I have new rotors as well on all 4 with pads as well.

Is there any sound coming from it by chance?

 

there's a chance ur new rotors could be warped. and when u say pulsating in the pedal, brake pedal or gas? also check ur lug nuts, i kno it sounds dumb but **** happens man

 

I have a 2001 a4 2.8l. its in the brake pedaland its been doing the same thing for a month or so now, i did the front brakes and it still was going on, a week or so later i did the back and its the same exact thing. when i use my hand brake evething feelsfine so i thought it would be the front but nothing has changed.

 

so what fixed it?
