hi all
bit of a problem with my 93 wrx i had new front pads and rear discs and pads fitted the other day and a day or so later on my way home from work i noticed a grinding noise coming from one of my passenger side wheels i think it may be the front but there is a possibility its the back. it sounded like a dull but repetative grinding noise and its only audible at low speed really but i think is down to my exhaust being loud. and now its really loud a few days and about 60 miles later the handling is fine and everything and it seems to dissapear if i press the brake lightly then come straght back but its a really annoying sound what could it be help please
