There is some variation on what Volvo installed on 700 & 900 series cars from the factory. In order to ensure you get the correct pads for your car please consult the front brake caliper photos above to eliminate any confusion. Externally, the calipers using #D508 and #D1198 pads look similar. To discern the difference, you must visually inspect the spring style on the pads. Once you remove the wheel, there is a small opening in the caliper where you can see the springs.
