when i stop the brakes pulse like your taking your foot off and on the brake only at about 10 - 15 miles an hour the pedal dose not pulse any ideas

it pulses at highway speeds?...sounds like warped rotors

no just like at 5 -15 mph when stopping not while driving

youve most likely got warped rotors. Gotta get em resurfaced at a brake shop, tire shops should do it to i think.
