MK1 Brake Servo

Item #: 21291 VW #: 171-612-107G

Brake Servo: Rabbit, Scirocco, Jetta & Others 77-93 - Reman, Adjustable

VW Rabbit brake servo. The brake servo (or booster) helps the master cylinder to create the required brake line pressure by using vacuum from the engine to apply extra pressure. If you need extra effort on the pedal to stop your Rabbit it is time to replace your brake booster servo. This remanufactured brake booster measures 9.5" in diameter, and is adjustable where the fork meets the brake pedal assembly. The studs for the master cylinder are 2.4" apart.
***These are available on a return and rebuild basis only - you send in your core and we rebuild it for you.
If you're not sure if your servo is rebuildable give us a call at 586-757-2300***

Refundable core charge: $75 applies. (Click here for more info)


Availability: In stock

Total cost: $324.95 (including FULLY REFUNDABLE core charges of $75)

Do-it-Yourself Tip

While installing this VW brake servo you will want to have new brake fluid ready. If you still have the original master cylinder installed on your Rabbit, consider purchasing a new one at the same time. You will the the master cylinder disconnected to complete the booster installation.
