OEM quality since the 1920s

Since the mid-1920s Continental has been supplying hydraulic brake master cylinders for motor vehicles. In addition, as brake system supplier, Continental utilizes its direct experience in overall hydraulic brake design. Therefore, the complete OEM experience and technology are incorporated into the ATE brand of master cylinders.

Nowadays, almost without exception the tandem master cylinder is installed as the basic unit for dual-circuit brake systems. It consists of two series-connected master cylinders in one housing. Operation usually is assisted by upstream devices such as brake boosters. We offer tandem master cylinders in expansion port and central valve versions.

Advantages and qualities of ATE tandem master cylinders

• Short closing paths
• Low volume uptake
• High efficiency
• Low throttling / after-suction resistance
• Low pressure differential between primary and secondary circuits
• Good bleedability
• Cr6-free surfaces for vehicles built from July 2007 (as required by law)
• Central valve version suitable for ABS

Plunger-type tandem master cylinder

As the basis for a standardized ATE concept for future tandem master cylinders, we have developed a new plunger generation that offers all the functions of the previous tandem master cylinder which has many technical enhancements and advantages:

• Compact design - ideal for installation in small spaces
• Reduced weight - by roughly 20% compared to conventional central valve technology
• Fewer components - almost half as many as compared to conventional technologies
• Modular system - diameters from 14.29 to 31.75 mm and strokes up to 46 mm
• Low volume uptake - minimized elastic deformations due to smaller seals
• Sealing cups supported in the housing -> robustness against soiling and wear; longer life
• Cr6-free surfaces for vehicles built from July 2007 (as required by law)
• Suitable for ABS
