Air Oil Hydraulic booster BST3, BST4

Air Oil Hydraulic Booster BST-4

BST-4 air oil hydraulic booster is an easy and small device which is usually morked with DBM hydraulic oil disc brake together. BST push rod of the master cylinder for automotive use which is activated by generate hydraulic pressure and then actuate the 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.
