Spring Brake - 3030 Combo Without Clevis
Bendix

This 3030 combo without clevis provides a compact, ready-to-install package with a 45 deg clamp angle and a 1.48 in stud length, a 2.50 in stroke, and a 4.75 in stud distance. The push rod length is 7.80 in, with 5/8-11 UNC-2A stud threads and 5/8-18 UNF-2A push rod threads. The ports include 3/8-18 NPT for service and parking lines, both oriented at 270 deg for routing flexibility. Temperature tolerance from -40 to 175 F ensures dependable performance in diverse climates, while the 30/30 chamber and standard S-Cam spring brake construction provide reliable braking force and modulation. This variant is designed for scenarios where clevis mounting is not required or where a piggyback or other mounting approach is used in conjunction with compatible base assemblies. VMRS code 013-004-027 underpins maintenance procedures, and category 41368 confirms its alignment with the S-Cam spring brake family for heavy-duty trucking and vocational equipment. Cross references should be checked against similar 3030 non-clevis configurations to ensure proper fit and compatibility.
