When replacing the brake master cylinder, it is absolutely essential to replace the brake fluid and thoroughly bleed the entire system. We also recommend inspecting the brake lines (both rigid and flexible) and the wheel cylinders.
A failed master cylinder (e.g., internal leak) leads to a loss of pressure in the brake system. This results in the brake pedal sinking to the floor and a total loss of braking ability. This is one of the most dangerous failures and can lead to a serious accident and loss of machine control.
The 15/904300 brake master cylinder is the primary hydraulic cylinder in the brake system. It is mechanically linked to the brake pedal. Pressing the pedal moves a piston inside the cylinder, which compresses the brake fluid and sends it under high pressure to the wheel cylinders, causing the machine to brake.

Use in a 3CX is possible but depends on the specific model and market. It is primarily listed for 4CX, Telehandlers, and RTFLs. Please verify the part number 15/904300 on your old part before buying.
This is the most common symptom of a failed master cylinder (worn internal seals allowing pressure to bypass). Other possibilities are air in the system or an external leak (e.g., at a wheel cylinder).
