Junction Block: Description

WARNING: This page is about a different car, the 2006 Dodge Magnum, 2006 Dodge Charger, and 2006 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.

A junction block is used on vehicles that are not equipped with antilock brakes (ABS) allowing use of the same brake tubes on all applications. The junction block is located in the engine compartment, in front of the right wheel well. The junction block mounts in the same location as the ABS integrated control unit (ICU) does on vehicles with ABS.

It has six threaded ports to which the brake tubes connect. Two are for the brake tubes coming from the master cylinder. The remaining four ports are for the brake tubes going to each wheel brake assembly.

The junction block contains a proportioning valve. The proportioning valve is not serviced separately from the junction block. For more information on the proportioning valve, (Refer to BRAKES/HYDRAULIC/MECHANICAL/PROPORTIONING VALVE - DESCRIPTION)
