Applicable truck models covered
This service manual applies to 3000-series International trucks — models 3200, 4100, 4200, 4300, 4400, and RXT — built between August 2006 and March 2007 under unit codes 04085 and 04JNG. It describes the master cylinder and reservoir, the Hydraulic Compact Unit (HCU), the Electronic Control Unit (ECU), wheel speed sensors, Electronic Brakeforce Distribution, and Automatic Traction Control (ATC). Bleeding requires a regulated pressure source and new DOT 3 or DOT 4 brake fluid, and ECU replacement is programmed with the EZ-Tech tool and TOOLBOX diagnostic software. For product details, visit the official International Trucks site at International Trucks.
Who needs this International 3000 hydraulic ABS manual
Brake technicians and fleet workshops servicing these 3000-series trucks need the manual for correct HCU and master cylinder replacement, pressure bleeding, and ECU programming. Only individuals with factory training should work on the Full Power Brakes system. Warning indicators flag low brake fluid, half-system failure, and full-system failure when a sensor detects pressure below 1550 psi in the accumulators.
