Brake Master Vac, Remanufactured, 70-72 240Z

Includes:

• (1) Remanufactured Brake Master Vac

Description:
An overly firm brake pedal is a common symptom of a bad Brake Master Vacuum unit (also known as a Brake Booster). These units typically fail when the internal diaphragm is torn or rots away over time. A bad check valve or vacuum hoses can also cause the booster to not work, so we recommend inspecting these as well. Sold on an exchange basis.

Measurements Note:
Nissan was inconsistent with some of the components used on the early model Master Vac. units. To ensure that we send the correct booster version to you, please measure the diameter of the threaded rod on the pedal side of the Booster (where the clevis is attached) as well as the length of the cap nut on the Master Cylinder side of the push rod.
