OPERATION

The junction block distributes the brake fluid coming from the master cylinder primary and secondary ports to the four brake tubes leading to the wheel brakes. Since the junction block mounts in the same location as the ABS integrated control unit (ICU), it allows for the common use of brake tubes on the vehicle whether it is equipped with or without ABS.

The junction block includes a rear brake proportioning valve. Placed in the fluid flow passages leading to the rear brake tube ports, it balances front-to-rear braking.
