Zusammenfassung:	To provide a brake control system capable of appropriately adjusting, by an adjuster, a clearance between a drum and a shoe.SOLUTION: A brake control system 10 comprises: a hydraulic unit 30 capable of adjusting a brake fluid pressure which is applied to a drum brake 20 so as to relatively move a drum and a shoe; and a shoe temperature obtaining part 40 capable of obtaining a temperature of the shoe. The drum brake 20 has an adjuster capable of adjusting relative positions of the drum and the shoe. When a first brake fluid pressure equal to or more than a predetermined high brake fluid pressure is applied to the drum brake and also an obtained value of the temperature of the shoe obtained by the shoe temperature obtaining part 40 is a predetermined temperature threshold value or more, the hydraulic unit 30 changes the brake fluid pressure to a second brake fluid pressure smaller than the first brake pressure.SELECTED DRAWING: Figure 1 【課題】ブレーキ制御システムにおいて、アジャスタによるドラム及びシュー間のクリアランスの調節を適切に行う。【解決手段】ブレーキ制御システム１０は、ドラム及びシューを相対的に移動させるようにドラムブレーキ２０に付加されるブレーキ液圧を調節可能とするように構成される液圧ユニット３０と、前記シューの温度を取得可能に構成されるシュー温度取得部４０とを備える。前記ドラムブレーキ２０は、前記ドラム及び前記シューの相対位置を調節可能とするように構成されたアジャスタを有し、前記液圧ユニット３０は、前記ドラムブレーキに所定の高いブレーキ液圧以上の第１ブレーキ液圧が付加され、かつ、前記シュー温度取得部４０によって取得される前記シューの温度の取得値が所定の温度閾値以上である場合に、前記ブレーキ液圧を前記第１ブレーキ液圧よりも小さい第２ブレーキ液圧に変更する。【選択図】図１
