90354661 GENUINE BRAKE MASTER PUMP

The 90354661 Brake Master Pump is a CNH Genuine hydraulic brake component designed for Case 570 SV and Case 570 ST units.
This part plays a critical role in the braking system, converting pedal pressure into hydraulic force to activate the brake calipers or wheel cylinders.

It ensures consistent braking power, safe machine operation, and long-term reliability, especially for machines operating in demanding construction or industrial environments.

Function of the Brake Master Pump

The brake master pump is the heart of the hydraulic braking system and performs key functions:

• Converts driver foot pressure into hydraulic brake force

• Maintains stable pressure within the brake system

• Ensures quick, responsive, and even braking

• Provides safe stopping distance under heavy loads

• Prevents air intrusion into brake lines

Without a functioning master pump, the machine will lose braking performance or fail to stop properly.

• CNH Genuine Part – perfect fit, factory-standard durability

• High-pressure resistant seals to prevent leaks

• Smooth hydraulic output for better brake response

• Precision-machined cylinder bore for long service life

• Improved stability and control when braking

• Designed for heavy-duty operations such as loading, roadwork, and municipal applications
