Oil Hydraulic booster BST2 for DBM air disc brake

Oil Hydraulic Booster BST-2 for DBM Air Disc Brake

There are two models of this oil hydraulic booster for DBM air disc brake, BST-2 and BST-4. They are with same structures, but with different cylinder head sizes. BST-2 matches with small cylinder head, while BST-4 matches with bigger cylinder head, so BST-4 hydraulic booster transfer torque is double of BST-2.
