The Cat truck brake system manual (publication UENR0738) is International’s August 2010 ADR-35 air brake service manual for the Caterpillar-branded CT610 and CT630 trucks. Across 30 pages it describes systems operation, removal and installation, and torque specifications for every air brake valve, gauge, and reservoir fitted to these vehicles. Air brake equipment on the CT610 and CT630 controls the brakes through a medium of compressed air.

Applicable truck models covered
This manual covers the CT610 and CT630 air brake-equipped vehicles built to Australian Design Rule 35 (ADR-35). Components documented include the foot valve, quick release valve (QRV), manifold valve (MV-3), tractor protection valve (TP-5), relay and antilock traction relay valves (R-12 and ATR-6), antilock modulator valves (M-32 and M-32QR), spring brake modulating valve (SR-7), hand control valve (TC-7), air dryer (AD-IS), solenoid pack, and reservoirs. Bendix supplies the foot brake valve linkage, which is factory-set and considered nonadjustable. Model and dealer details are on the official Caterpillar website at cat.com.
Who needs this Cat truck brake system manual
Brake technicians and fleet workshops maintaining CT610 or CT630 vehicles use this document for correct valve replacement, push-to-connect air line fitting service, and the factory torque chart. It also warns against adjusting the nonadjustable Bendix foot valve linkage. Air pressure gauges use pressure switches to register primary and secondary reservoir pressure, and the low pressure indicator sounds a buzzer below roughly 65 to 70 psi.
