Dual Proportioning Valve: Inspection

WARNING: This page is about a different car, the 2009 Nissan Sentra. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION:

Carefully monitor brake fluid level at master cylinder.
Use the recommended new brake fluid.
Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is splashed on paint areas, wash it away with water immediately.

Connect commercially available brake fluid pressure gauge to air bleeders of front and rear brakes on either LH and RH side.
