Product Description
A brake master cylinder is the heart of a tractor’s hydraulic braking system, converting pedal force into pressure to engage the brakes. This 19mm bore master cylinder (OEM 531962452712 / 62452712) is engineered for Zetor 3320 & 4320 tractors, providing reliable stopping power in demanding conditions.
How It Works:
-
When the brake pedal is pressed, the piston inside the cylinder compresses brake fluid, transmitting force to the wheel cylinders.

The 19mm bore size ensures optimal pressure balance for smooth, responsive braking.
Ideal For:
-
Farm equipment repair centers
