Therefore, the specific structural and functional details described herein are not to be construed as limiting, but rather on a merely representative basis to teach one skilled in the art the various modes of application of the present invention.
    Referring to Figures 1 and 2, an exemplary brake caliper assembly 10 is shown. The brake caliper assembly 10 may be provided as part of a vehicle, such as a motor vehicle such as a truck, bus, agricultural equipment, military transport or weapons vehicle, or cargo handling equipment by land, air, or sea vessels. In at least one embodiment, the brake caliper assembly 10 can include a housing assembly 20, a first set of brake pads 22, a second set of brake pads 24, a pad shield 26, and a support. retention 28.
    The housing assembly 20 can receive various components of the brake caliper assembly 10. Additionally, the housing assembly 20 can facilitate the positioning of the first and second sets of brake pads 22, 24 relative to a rotor, also known as a disc in order to facilitate the braking of the vehicle. In at least one embodiment, the housing assembly 20 can include a carrier 30, a collet housing 32, and a collet bridge 34.
    The carrier 30 can be fixedly mounted to the vehicle.

Each flap slot 96 may be spaced apart from the inner channel 90 and second side 82. Alternatively, a flap slot 96 may not be spaced apart from the second side 82 in one or more embodiments. A flap groove 96 may receive an inner flap 70 of the second set of brake pads 24 when the second set of brake pads 24 is properly oriented (e.g. with friction material 52 of the second set of brake pads 24 facing the first set of brake pads 22, and the inner flaps 70 facing the pad shield 26). As such, the tab slots 96 can help facilitate proper installation of the second set of brake pads 24.
    One or more openings for tab 98 may be provided with insert shield 26. In the embodiment shown, two openings for tab 98 are provided. Each opening for tab 98 may be disposed adjacent to the second side 82 and a outer channel 92. An opening for flap 98 may or may not be spaced apart from the second side 82 and outer channel 92. In the embodiment shown, each opening for flap 98 is spaced apart from a corresponding outer channel 92, and is configured as a notch extending from the second side 82. The openings for the tab 98 may also be disposed adjacent to a gutter 94 or between a gutter 94 and a proximal end surface, such as the first end surface 84 or the second end surface. end 86. Each flap 98 opening may receive an outer flap 72 of the second set of brake pads 24.
    Retaining bracket 28 may be disposed over housing assembly 20. Retaining bracket 28 may engage central portion 88 of chip shield 26 and may have first end 100 and second end 102. First end 100 may engage or it may be received in a notch of the collet housing 32. The second end 102 may be disposed opposite the first end 100 and may be fixedly disposed on the collet bridge 34. For example, the second end 102 may engage the collet bridge 34, and may have a hole that receives a fastener 104, such as a screw, that can attach the retaining bracket 28 to the collet bridge 34.
    The pad shield 26 and the retaining bracket 28 can cooperate to exert a force against the first and/or second sets of brake pads 22, 24. More specifically, the retaining bracket 28 can exert a force on the pad shield 26, which in turn can exert a force on the first and/or second sets of brake pads 22, 24 to help position the first and/or second sets of brake pads 22, 24 within the housing assembly 20 and inhibit movement relative to insert shield 26 to help extend friction material life and reduce noise. This configuration may allow the brake pad springs to be omitted from the brake caliper assembly 10. A brake pad spring may resemble a leaf spring and may be a separate component that can be provided on the third surface. 64 between a support plate and an insert shield. These brake pad springs can be difficult to see under a pad shield and can be misplaced or inadvertently omitted during assembly. Eliminating brake pad springs eliminates incorrect assembly of brake pad springs, reduces the number of parts supplied with a 10 brake caliper assembly, and reduces associated costs. Additionally, the pad shield 26 can be configured as a standardized component that can be used in different sets of brakes.
    Although exemplary embodiments have been described above, these embodiments are not intended to describe all possible forms of the invention. Rather, the words used in the specification are descriptive and not limiting words, and it is understood that various modifications can be made without departing from the spirit and scope of the invention. Additionally, features from various embodiments can be combined to form other embodiments of the invention.
