Installation Notes and Tips

Verify the brake code on the vehicle Service Parts Identification sticker before ordering. Confirm the vehicle is equipped for a vacuum power brake booster and, where listed, that it matches JD9 or JL4 configuration requirements. This unit is for vehicles without a master cylinder, so reuse or replace the master cylinder separately as needed. Check the master cylinder stud thread size and booster-to-master cylinder interface before installation.
