total balanced braking is a product of torque or foundation balance, pneumatic pressure balance, pneumatic timing balance, and temperature balance.torque balance. this deals press with the hardware parts of a brake system. factors 20 that affect torque floor balance hand drill press include: different angles between slack adjusters and brake chamber push rods, improper lining-to-drum contact, different size press and 20 brake drums, mismatched brake return springs, different friction values of lining on the same axle, and improper brake adjustments. for a five-axle vehicle combination, a proper torque balance would floor have 20% of braking effort on the steer axle, 40% on the drive drill axles and 40% on the trailer axles. pneumatic pressure balance. this pertains to the proper air pressure delivered equally to all wheels so that each wheel does its share of braking based on the proportion of weight being carried.
