During pressure front RH brake caliper increases

WARNING: This page is about a different car, the 2011 Nissan Juke. However, it is still accessible from the selected car via links, so may be relevant.

Brake fluid is conveyed to the pump from the master cylinder through suction valve 2 and is pressurized by the pump operation. The pressurized brake fluid is supplied to the front RH brake caliper through the ABS IN valve. For the left caliper, brake fluid pressure is maintained because the pressurization is unnecessary. The pressurization for the left caliper is controlled separately from the right caliper.
