Installation Notes

Confirm master cylinder fitment, stud thread size, and booster dimensions before installation. Because the master cylinder, gasket or seal, front seal, mounting bracket, and pedal rod extension are not included, transfer or source the required related components as needed for the repair. Verify vacuum supply, pedal linkage alignment, and mounting points during installation on the Chevrolet Silverado 1500, Chevrolet Cheyenne, or GMC Sierra 1500.

MPA Electrical tests each booster at the end of the production process using proprietary equipment to confirm braking assist performance and vacuum seal integrity. The remanufactured B1317 is prepared to meet standard replacement expectations for select 2007 Chevrolet and GMC truck applications.
