s13brakes HELP!!
 

Ok so here is my story.. I took a drive thursday and it felt like my calipers were sticking(It sounded like iwas brake boosting). So i got it back home jacked it up and spun each wheel and they all spun freely. So the next day i started to go to school and it started doing the same thing again. So i pulled over and went by each wheel and took a wiff and both front brakes had a strong smell of burning brakes but the rears didnt have a smell at all. The brake pedal felt normal but then would get stiff. I need to fix this asap. Any help would be great Thanks.

Sounds like the pistons are going out, new calipers or a rebuild

Im going to see if the pads are getting stuck in hte retainers first before i spend any money on calipers.
