Abstract

PURPOSE:To reduce the wear of front brake shoes at descending slope or the like by enabling the brake action of an inside-expansion type front brake at descending slope or the like to operate and enabling the above brake to operate by operating an emergency valve. CONSTITUTION:In a vehicle to which front wheels are provided with inside- expansion type brakes 10 and rear wheels with wet multi-disc type brakes 17, a brake valve 21 is provided so as to supply the pneumatic pressure in a pneumatic pressure tank 22 to the first pilot receiving part 151 of a relay valve 15 via a front brake switchover valve 23 as well as the 1st pilot receiving part 201 of a relay valve 20. An emergency valve 24 is also provided so as to supply the pneumatic pressure in the pneumatic pressure tank 22 to the 2nd pilot receiving part 152/202 of the relay valve 15/20, respectively. The pneumatic pressure supply to the brake 10 is interrupted by switching over the switchover valve 23 to the drain position II at descending slope or the like and at the same time the both brakes 10 and 17 are made operatable by operating an emergency brake valve 24.
