like the title saids my front driver side brakes spark when i press the brakes even when im goin slow i took my tire out and everything look good so wat can this be..ok i took it to my uncles shop cuz they were the one that did my dics and pads job bout 2 to 3 month ago so i took it back to them to check it out and see if they see something i didnt. this is what happen me and my homeboy riding when he pull next to me and said there is spark coming from your left front wheel i saw it than it stop for a few days than it did it again two nights ago driving home from a meet so

 

what brake pads?
how hard were you on the brakes when this happened?
do the rims/rotors get hot when you drive it?

 

Kinda out there, but check the little metal piece on the brake that's supposed to squeak when your pads get low. Also, I had my dust cover behind the rotor touching, that made a few sparks, but it also made a slight screeching sound, so I noticed pretty quick.
