Check engine light A world to learn
Any auto parts store can sell you brake pads, but be sure to give them the make and model of your car as the pads may vary from make to make. Back home with your car in the driveway, the next step is to jack it up and remove the wheel. You will have completed the bulk of your brake repair with these two tasks. If you still are not sure that brake repair is necessary, you can eyeball the pads through the brake housing view port before removing the wheel. If you determine that brake repair really is necessary, then your next step is to remove the wheel and the bolt or bolts holding the brake housing in place and swing the unit out of the way.
