Service break system used to force the vehicle to show down and keep a steady speed when downgrading. The parking break system intended to hold the vehicle immovable when parked on an incline. This design carries on the synthesis analysis to the drum type of the brake structural style . par es the advantages and disadvantage s of six kind s of forms, and according to this contrast analysis of the kind s of the brake plan, the horseshoe type ’s brake is adopted. Its main merits are that although t he brake efficiency and the stability are in the medium level, because t he automobile braking performance is invariable when going ahead and going backwards, the construction cost is lower, and it attaches installs in the vehicle ’s driving mechanism and a djust s the gap between the brake shoe patch and the brake drum easily. The design uses manual hydraulic break and series connected double cavity general pump. Both the front and rear break is double leading-rear break. According to the vehicle ’s parameters and the break ’s parameter, after theory analytic and calculating, we analyzed the breaking force and direction stability when breaking specifically.
