If it is your first time changing break pads, I would do the following :
- Get a DIY manual from Canadian Tire on your model, or look up how to do it on the internet.
- Remove the bolts and place them in a line, this way you know how they came off the car. When you put them back on, it will be the reverse order.
- Remove the break pads from the caliper, if the new ones do not slide in easily you may have the wrong replacements. ( I once had the wrong pads, do not force them in or the pads may bind in the calipers )
- You may not need to sand the rotors, if they are smooth let them be. If you scrape your finger nails on the groove and they are quite rough, you can sand them with a cordless hand drill and sander head doing circular motions around the edge of both sides of the rotor.
- Reverse the process to re-install the brakes.
Most likely you will not need to replace or sand your rotors. If the grooves are not too deep, you do not have to sand the rotors. I have been doing my brake jobs for 12 years and I have had no problems just replacing the pads. If your rotors are not in good shape, check out the prices for a new rotor, it may be almost the same price as resurfacing the rotors. Go with ceramic brake pads, they will last 3 times as long as regular pads.
