The capacity to brake will gradually deteriorate forcing the driver to use a higher than expected force on the brake pedal when compared to an intact brake system. The deterioration can eventually result in complete loss of the brake system functionality increasing the risk of a crash.

Volvo is recalling 1,114 MY 2007 C30, C70, S40, and V50 passenger vehicles. A soft anodized layer in the master cylinder may trigger early wear on a rubber seal that can result in internal leakage of brake fluid. If affected, the driver may experience reduced brake performance when applying and maintaining force of the brake pedal.
Dealers will inspect the master cylinder. The brake master cylinder and brake fluid reservoir will be replaced and certain brake lines cleaned free of charge. The recall began on March 11, 2008. Owners may contact Volvo at 1-800-458-1552.
