Owning a car means constant maintenance, and high-performance brakes are one of those parts you really should not ignore once you hear the first squeak. When you replace them, you are paying for both the parts and the labor to get them installed correctly.
Prices for good pads are usually fairly steady, but you can sometimes find deals during slow repair months like February or August. If you have the cash, pay it upfront, but if you need to stretch it, we can look at a specific card strategy.
Remember that the 0% intro APR window is a deadline, not free money. If you have any balance left after the 15 months are up, the card will start charging you interest on whatever you still owe.
