Installation Notes

Verify the vehicle’s hydraulic booster configuration, master cylinder stud thread size, and mounting layout before installation. This unit does not include the master cylinder, brake pedal rod extension, or gasket/seal, so those components must be confirmed separately during service. Use the included mounting bracket as specified for the application and follow factory service procedures for bleeding and system setup after replacement.
