The unit uses specially treated replacement components to help maintain vacuum seal integrity and pressure transfer, and it is end-of-line tested to verify function before release. This part cross-references Volkswagen OE numbers 1H1 612 107 C and 1H1612107C for the same application.\u003c\/p\u003e\u003cp\u003eCompatible with Volkswagen Cabrio, Golf, and Jetta applications from 1993-1999, this booster is a direct service replacement for vehicles requiring a vacuum brake booster without a master cylinder. It is a practical choice for Volkswagen Golf and Volkswagen Jetta brake repair when the original booster has lost assist or vacuum retention. The B3108 part number should be matched to the vehicle’s brake system specifications before installation.\u003c\/p\u003e\u003ch2\u003eCommon Repair Issues\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eHard brake pedal feel caused by reduced vacuum assist.\u003c\/li\u003e\n\u003cli\u003eLoss of braking boost from a leaking booster diaphragm or seal.\u003c\/li\u003e\n\u003cli\u003ePoor pressure transfer between the pedal and master cylinder.\u003c\/li\u003e\n\u003cli\u003eBrake system performance issues related to a worn remanufactured replacement unit.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Quality\u003c\/h2\u003e\u003cp\u003eVerify master cylinder stud thread size, mounting stud layout, and booster-to-master cylinder compatibility before installation.
