Spring is a great time to administer care toward your Volvo luxury SUV. Your Volvo most likely incurred some wear and weathering over the winter. And any issues be they noticeable or not may exponentially become worse if not remedied in a timely manner. With brake calipers and rotors, the telltale signs might be obvious and others perhaps not.
Obviously, brake calipers and rotors need to work in conjunction. Should there be serious wear it could signal issues with tire alignment or just a simple refurbishing.
It's easy to inspect the brake system of your Volvo. While bending or kneeled, look through the spokes and note if the rotor has been ground below the casing. Such a condition will be noticeable when applying the brakes given squeaks or grinding.
