| 摘要 |
The application discloses a brake assembly capable of providing a park/emergency brake facility and a service brake facility acting on the same friction pad or friction pad pair, the assembly including a rotatable disc rotor (23), at least one friction pad (27) adapted for movement towards a braking surface (25) of the disc rotor (23) to provide a braking effect, the assembly further including a first brake activating means (62, 63, 40) to provide the park/emergency brake facility operable selectively to urge said one friction pad (27) towards the braking surface (25) of the disc rotor (23), a second brake activating means (66, 32) to provide a service brake facility selectively operable independently of said first brake activating means to urge said one friction pad (27) towards said braking surface (25) of the disc rotor (23), and third means (71, 31) normally acting to prevent said first brake activating means (62, 63, 40) from urging said one friction pad (27) towards the braking surface (25) of the disc rotor (23).
