Hey guys im new to the forums. I recently replaced my front pads on my spectra and now im getting like 15miles to the gallon, about 220miles to the full tank. I was getting 300/tank until i changed them. I have the right pads for sure but i am getting a rubbing sound when the brakes are pressed lightly when at low speeds, like barely moving speeds. I had a little trouble compressing the piston on one of the calipers but i dont think that the rubbing is coming from that caliper. Could it be the rear brakes locked up? Maybe the right side, even though i had no problems compressing the right side caliper? My car only has 60,000miles. Any suggestions would be greatly appreciated.
