I see from your other posts it is an Eziset (Simpson) You would of received help quicker if you had put make & model details in the first time & stuck to one posting instead of 3. Anyway, it sounds like the brake arm that the pawl is attached to is not pulling out and releasing the brake. Suggest you check if the bawden cable from the brake release motor is still attached to the brake arm.
