According to customer reviews the best brake pads and rotors are EBC brake rotors and pads. They are manufactured in Britain and can be found at any auto store including Canadian Tire in Canada.
When rotors need to be changed usually the pads have worn down. It is always a good idea to change pads when changing rotors.
There's nothing better then the GM. factory pads and rotors.Bendix rotors and pads are real good if you can find it.Wagner brake parts are good too.
If the rotors are in good condition, not warped, not scratched, then you can replace the pads without turning the rotors. Inspect the rotors carefully.
If rotors are smooth and shiny, they are good. If still not certain, ask at brake shop.
I recently got a quote for my 2003 Kia Optima brake pads & rotors to be replaced in the rear and it came to $183 before taxes. This price is to replace both pads and rotors completely. Usually rotors don't cost much to be turned.
In may area around $150.
Expect to pay about $275/300 per axle for quality brake pads and new rotors.
pads
Brake calipers are the hydraulic devices that wrap around the rotors and pinch the brake pads into the rotors when you stop.
Some as the pads and rotors break in but it shouldn't be excessive.
Possible wrong rotors???
