Raybestos MC390699 Element3 New Brake Master Cylinder

The Raybestos MC390699 is a professional-grade, new brake master cylinder engineered as a direct OE replacement. Part of the Raybestos Element3® line, this master cylinder is manufactured to match or exceed original equipment fit, form, and function, restoring proper hydraulic brake system performance.

The brake master cylinder is the heart of your vehicle's hydraulic braking system. It converts the mechanical force from the brake pedal into hydraulic pressure, which is then distributed to the brake calipers and wheel cylinders to slow and stop the vehicle. A failing master cylinder can result in a spongy pedal feel, loss of braking pressure, or a pedal that sinks to the floor — all signs that immediate replacement is needed.
