7. Brake calliper testing apparatus according to claim 6, wherein the load cell is connected to one of the two first test plates, the testing mechanism further comprising a contact block connected to the other first test plate for contact with the load cell.

8. The brake caliper testing device according to claim 7, wherein the two first test plates have a close-up force measuring position, a distance measuring position separated in a lateral direction from the force measuring position, and the testing mechanism further comprises a position sensing element for sensing whether the two first test plates are in the force measuring position.

9. A brake calliper testing apparatus according to claim 3, wherein the bracket means comprises a post upstanding from the base and located rearwardly of the testing means, an extension beam connected to the upper side of the post and extending forwardly therefrom, a connection assembly connected to the extension beam, the brake calliper testing apparatus further comprising a first or second mounting member connected to the connection assembly, the first mounting member for securing a conventional brake calliper and the second mounting member for securing a compact brake calliper.

10. The brake caliper testing device according to claim 9, wherein the connection member is provided to be adjustable in a front-rear direction with respect to the extension beam, and includes a first position to which the first mounting member is connected when the connection member is in the first position and a second position turned from the first position to which the second mounting member is connected when the connection member is in the second position, and an adjustment amount of which is adjustable in a front-rear direction with respect to the extension beam is different when the connection member is in the first position and the second position.
