Turn brake-pedal effort into the hydraulic pressure that pushes fluid through the brake system with the Dorman - First Stop Brake Master Cylinder M93065. It installs as a direct-fit replacement precision-engineered to match the design, function, and performance of the original master cylinder on the 1954-1964 Volkswagen Beetle [All] and 1961-1964 Volkswagen Karmann Ghia [All].
A brake master cylinder converts the force from the brake pedal into the hydraulic pressure that operates the wheel brakes. If a worn or leaking master cylinder is the cause of a sinking or spongy pedal or a loss of braking pressure, this replaces it. The reservoir, sensor, and mounting hardware are not included; consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: China.

Manufacturer part number M93065.
This part cross-references / interchanges with the following part numbers:
What does the M93065 master cylinder do?
It converts the force from your brake pedal into the hydraulic pressure that operates the wheel brakes, moving glycol-based brake fluid through the system.
Which vehicles does it fit?
It's a direct-fit replacement for the 1954-1964 Volkswagen Beetle [All] and the 1961-1964 Volkswagen Karmann Ghia [All]. See the Buyer's Guide tab to confirm your vehicle.
Does it include a reservoir or mounting hardware?
No. The reservoir, sensor, and mounting hardware are not included, so transfer or source those separately and check the service procedure for the correct fasteners.
What is it made of?
The cylinder housing is cast iron, matched to the original casting material, and all rubber components use a high-quality EPDM compound for resistance to glycol-based brake fluid.
What are signs the master cylinder may need replacing?
A brake pedal that slowly sinks or feels spongy, or a loss of braking pressure, can signal a failing master cylinder. Diagnose the cause first, since other components can produce the same symptoms.
