Abstract
A brake system comprising: (a) a rotor; and (b) two or more brake assemblies in communication with the rotor, the two or more brake assemblies each including: (i) a caliper; (ii) a piston assembly located within the caliper; and (iii) a motor gear unit in communication with the caliper and configured to move the piston assembly to create a braking force; wherein one or more both of the piston assemblies are moved during a service brake apply or release; and wherein one or both of the piston assemblies are moved during a parking brake apply or release.
Claims23
1) A brake system comprising:
- a. a rotor;
- and
- b. two or more brake assemblies in communication with the rotor, the two or more brake assemblies each including:
- i. a caliper;
- ii. a piston assembly located within the caliper;
- and
- iii. a motor gear unit in communication with the caliper and configured to move the piston assembly to create a braking force;
- wherein one or more both of the piston assemblies are moved during a service brake apply or release;
- wherein one or both of the piston assemblies are moved during a parking brake apply or release;
- and
- wherein a controller powers a first and a second of the two or more brake assemblies and the controller powers both the first and the second of the two or more brake assemblies until brake pads of the two or more brake assemblies contact a rotor and then the controller alternates power between the first and the second of the two or more brake assemblies.
6) The brake system of claim 13, wherein the motor gear units move a first and a second of the two or more brake assemblies during a parking brake apply or release.
7) (canceled)
8) (canceled)
11) A brake system comprising:
- a. a rotor;
- and
- b. two or more brake assemblies in communication with the rotor, the two or more brake assemblies each including:
- i. a caliper;
- ii. a piston assembly located within the caliper;
- and
- iii. a motor gear unit in communication with the caliper and configured to move the piston assembly to create a braking force;
- wherein one or more both of the piston assemblies are moved during a service brake apply or release;
- wherein one or both of the piston assemblies are moved during a parking brake apply or release;
- and
- wherein a controller controls movement of the two or more braking assemblies so that the braking force created by all of the two or more braking assemblies are substantially a same force.
14) (canceled)
15) A method comprising:
- a. supplying a signal to both a first brake assembly and a second brake assembly simultaneously;
- b. alternating the signal between the first brake assembly and the second brake assembly once contact between the first brake assembly and a rotor or the second brake assembly and the rotor is detected;
- and
- c. applying the first brake assembly and the second brake assembly until a predetermined braking force is generated.
