An improved expanding shoe drum brake (10) is provided. The brake includes a shaft-like mounting structure (42) for retaining the hook ends (40) of a heavy duty brake return spring (28). The retaining assembly includes a fixed portion (44) and an axially movable portion (46). The axially movable portion is normally abutting with the fixed portion but may be selectively axially moved away therefrom for assembly and disassembly of return spring (28) from the brake assembly (10). |
