General Requirements

• Anti-compounding air system
• Cam same operation for all steerable axle brakes and EB1807R brakes
• Air chamber bracket with gusset for all refuse applications, see page 45
• Air chamber bracket assembly gusset and additional camshaft bracket support see page 45, attached to the axle housing

when the:

a. Brake centerline to air chamber centerline distance (BCCC dimension) is greater than 343 mm [13.5”]
b. Application use a type 30/36 or 36/36 Spring brake chambers.
c. Camshaft brackets with BCCC dimension of less than 8.12” does not require a gusset or additional support.
d. Super Single Tire (Wide Base)
Note: The above support can be supplied by BSFB or the vehicle manufacturer but

must be approved by BSFB Application Engineering Department.

• Applications for use in countries other than the USA and Canada must be reviewed by BSFB Application Engineering.
• Trucks equipped with remotely controlled neutral brake engagement valves must incorporate a pressure limiting device set

to a maximum pressure of 60 psi and must supply air pressure to all service chambers on the vehicle

• Vehicle manufacturer is responsible for air system design, parking and stopping distance performance.
• For all brake models the camshaft input torque is limited to 2545 N•m [22,500 in-lbs].
• Applications on vehicles with fi xed or liftable auxiliary axles (tag or pusher) must be approved on an individual basis by the

BSFB Application Engineering Department, as auxiliary axles may impact the braking performance of the vehicle.

General Recommendations

• Cam same for all brake assemblies
• Dust shields for all applications
• Use Auxiliary retarders per TMC RP636
• Brake drum / Rotor material specifi cation per SAE J431. Drum / rotor surface fi nish 4.57 micrometer [180 max microinch]

and .38 mm [.015”] runout, when mounted on a hub rotated on bearings. See notes section for Minimum Drum Weight
requirements

• Brake air system balance per TMC RP632
