Dynamic Friction Company Brake Master Cylinder P/N:355-31018
Dynamic Friction 355-40079 brake master cylinder for the 2011 Ram 2500 and other vehicles turns pedal force into hydraulic pressure for the brake system.
A soft or sinking brake pedal, brake fluid around the master cylinder or a brake warning light can mean the master cylinder is worn, though a leaking brake hose or a faulty caliper can be behind them too, so trace the cause before you replace anything.
The vehicles this Dynamic Friction brake master cylinder fits include the 2011 Ram 2500, the 2006-2009 Dodge Ram 2500 and the 2011 Ram 3500, and each takes one. For any other truck, open the "Vehicles it fits" section and look up your exact model and engine.
