Installation Notes

Verify the brake code on the Service Parts Identification sticker before ordering. This application is for vehicles with Brake Code JD7 where noted, and the master cylinder is not included. Confirm the master cylinder stud thread size is M10 x 1.50 and compare the original booster configuration before installation. Follow the included instruction sheet and inspect the hydraulic connections and O-ring sealing surfaces during replacement.
