Installation Notes and Tips

Verify the vehicle’s brake system configuration before ordering, since listed Volvo applications exclude vehicles with Collision Warning and Auto Brake Control. Confirm the 9-inch housing diameter, dual-diaphragm design, and brake pedal rod extension requirement against the original unit. Because the master cylinder, mounting hardware, and mounting bracket are not included, reuse or source the needed related components separately as required by the vehicle.
