PROBLEM TO BE SOLVED: To provide a friction brake system that enables allocation to each brake by estimating a friction coefficient and can highly accurately attain stable vehicle behavior and brake feeling during braking of a friction brake.SOLUTION: A friction brake system includes: braking force allocation means 12 for outputting a load command value to friction brake devices 3 for a plurality of wheels; and a friction coefficient estimation calculation section 14 for estimating a friction coefficient between a brake rotor and a friction material of each of the friction brake devices 3. The friction coefficient estimation calculation section 14 includes: an allocation control section 15 for changing allocation of brake pressing force allocated by the braking force allocation means 12 to estimate the friction coefficient; and an estimation calculation section 17 for estimating the friction coefficient from a relationship between the load command value of which allocation has been changed and deceleration of a vehicle.SELECTED DRAWING: Figure 3
