When doing a build on your VW dune buggy or VW sand rail, there are several options that you have when it comes to a VW master cylinder. If you are looking to just replace the vw master cylinder, there is a stock VW master cylinder that will fit your VW dune buggy and VW sand rail. The stock replacement master cylinder is the EMPI brand and is of good quality. If you are wanting to spice up your sand rail, we also offer a VW chrome brake master cylinder. This will add some character to your build. Looking to get the VW master cylinder and the reservoir in one shot? We've got that package all ready for you. To buy these two parts together will save you a few bucks, as the reservoir and the master cylinder are bought together in most instances. We have multiple different VW reservoirs that are available. We have a press in style brake fluid reservoir, a thread in VW brake fluid reservoir and two styles of billet brake reservoir. If you need help determining which set up is best for you, our VW technical support can help you at 1-800-955-9795.
