7" Zinc Street Rod Rat Rod Power Brake Booster w/ Bail Top Master Cylinder




New 7" booster with master cylinder.  The master cylinder is used for disc/disc or disc/drum brakes. This same set is usually seen for over $220, so the deal is here.  These are often used under the floor of street rods and hot rods.  These is the best deal you'll find on a quality setup like this.  Take advantage of our huge buying power and get this quality setup before it runs out!!

If you need a booster for a little heavier vehicle, go with the 7" DUAL Diaphragm, available in my eBay store.  It offers 27% more stopping power over the single booster, making it ideal for the larger vehicles.

When mounting a master cylinder beneath the floor, I have a variety of necessary accessories such as the following, which are available in my eBay store:

  • A 2 pound valve (for disc applications).
  • A 10 pound valve (for drum applications).  You may also want an adjustable proportioning valve.  
  • I offer several adjustable proportioning valves.
  • I also offer some extremely nice self-adjusting combination valves.
