Boosted Master Cylinders

For Machinery Requiring Higher pressures

MICO Boosted Master Cylinders are used on machinery that require higher pressure than typically provided by master cylinders or two-stage master cylinders. 

The same dependability and performance that goes into every MICO braking system product also goes into our versatile, high-performance off-highway boosted master cylinders.

Boosted Straight Bore 
Boosted Master Cylinders

The single piston straight bore type master cylinder has been proving its usefulness since the early 1930's and is still in extensive use. 

 

Provides natural pedal "feel" through hydraulic reaction

Completely hydraulic - no vacuum or air assist required

Stem Seal Type
Boosted Stright Bore Master Cylinders

By eliminating the equalizing port normally found on master cylinders, this cylinder offers simplicity, ease of bleeding and versatility. The lack of compensation port allows the cylinder to be used in a broad range of applications indiscriminative of volumetric output.

Boosted Dual Master Cylinders
Intented for Bake Systems with Brake Assisted Steering

The MICO Boosted Dual Master Cylinder is used to Modulate output pressures up to 1500 PSI. This is used in conjunction with properly sized brakes using mineral base oils and booster oil from a standby pressure source such as that of a transmission. This unique integrated design can easily adapt to many dual systems to provide steering assist power braking with one pedal applied or full power braking with both pedals applied giving equally balanced brake pressure.

 

Power-off braking through master cylinder

Open center spool construction provides smooth brake modulation at all pressures

Direct acting pistons provide pedal "feel" accurately representing brake pressures

Balance piston seals fluid loss from one master cylinder side should the opposite side brake line become severed

Reduced pedal force during steering assist braking

Boosted Open Center
Boosted Master Cylinders

The MICO Open Center Master Cylinder, also called MICO Open Center Valve, permits the addition of a power braking system to vehicles which are equipped with other hydraulic power devices such as power steering or implements.

Elminates the need of a separate power brake unit

Provides natural pedal "feel" through hydraulic reaction

Pressure in the brake system can be double that of the main hydraulic system

Full hydraulic flow and pressure are retained for downstream components, except for the small volume required to displace brake cylinder pistons during brake applications

Hydraulic Power Brake Actuator
Boosted Master Cylinder

The MICO compact size Hydraulic Power Brake Actuator is designed for use with vehicles that are equipped with an open center hydraulic system that can supply 0.7 to 4 GPM at 335 PSI to obtain the set brake limit pressure. It can be operated manually through the booster during power-off conditions. 

MICO Hydraulic Power Brake Actuator combines a hydraulically boosted power section with a master cylinder section in a single unit. This valve uses mineral based hydraulic oil in both the booster and master cylinder sections. The master cylinder section is separate from the booster portion so an alternative fluid such as transmission oil can be used for the brakes.
