DESCRIPTION:
This is a brand new 7" CHROME SINGLE brake booster.
This 7" booster is ideal for most small to mid size street rods and customs.
The booster mounts with a 4-bolt pattern.
The 4 bolts are in a perfect square and are 3 3/8" apart (center to center).
The booster requires 18" of vacuum to operate properly.
With this vacuum level the booster will produce a maximum pressure output of 950 psi with a 1" bore master cylinder.
This pressure level works well for four wheel drum systems and disc/drum vehicles which are relatively light.
