So, I just swapped out my front brake pads, turns out the shop that had done the brakes previously decided they would only shim three of the pads and not the fourth. Anyways, one of the pads (inside right, I think) is now rubbing, causing the car to pull. What do I need to adjust to take care of this?

 

if its rubbing... or should i say GRINDING... its probably trashing your rotor or drums right now!!!!!!!
tho i ve never heard of shimming brake pads myself... but ive only done the rear drums on imports and then just american cars....
i havent done my front brake pads on my civic yet but i do want to replace my rotors and pads eventualy. so i guess ill find out when i get that far...

 

It might be possible that the previous mechanic forgot to place that last shim on.
Or maybe the caliper is not releasing properly,(frozen).
Don't forget that disk brakes are always dragging,(slightly).
