Abstract: A solenoid attachment for a vehicle antilock brake system. The solenoid attachment includes a coil pack housing (10) having leadframes (12) electrically connecting to a circuit board (22) of the electronic control unit (24). The solenoid attachment also includes a plurality of solenoid assemblies (26). Each solenoid assembly (26) includes coil windings (48) and a bobbin (46) contained within a can (52). A retention ring (58), including retention snaps (60), is associated with each solenoid assembly (26) for removably retaining each solenoid assembly (26) in the coil pack housing (10). Each solenoid assembly (26) is further mounted to an elastomeric gasket (56) that both seals about an adjustment gap (53), open to the electronic circuit board (22), and biases the solenoid assembly (26) against its corresponding valve (40). A sealing mechanism (66, 98) is provided with each valve assembly (26) for sealing around an associated valve stem (42).
