Wanna get your Dune Buggy stopped? The master cylinder is the heart of your brake system. This is the master cylinder you need. This is a dual circuit buggy master cylinder. This uses a 113 611 015BD master with a new reservoir that snaps right on top in place of the filler tubes! Compared to hanging your reservoir off the bars this is a clean slick setup. Direct bolt in for stock VW pedal setup. Has three brake line ports and one brake light port. Brand new, never been used. This is a DUAL CIRCUIT so you aren’t depending on one like most buggy master sold, this really is a superior setup. We use them on our buggy and rails with EXCELLENT results.
