hey bro, im having he same damn problem i just replaced my brakes and my front passenger brake caliper and it didnt do **** still acts like it is catchin on something also since i put new brakes on it i can smell it burning the new brakes bad. Also the check engine light is on but its saying EGR tho(paperclip trick) So i bleed the brakes to, didnt do anything, the master cylinder looks like it has been replaced before tho, because its new and shiny. i have had my toyota for 2 months. and it hasnt been nothing but a piece of ****. anyways where is that abs sensor thing... the brake problem is coming from the front i know that much... next time im going to let them lock up after driving and then jack it up and spin the wheels which seem to be like they locking up. any tricks or secretes i should know please let me know!!

edit!!!
also the brakes work fine till after about 20 minutes of driving then brakes get hot then they seem to lock up
