The cooling grooves extend partially into the plate body to provide additional cooling of the brake pad and braking assembly. The planar caliper piston contact area is configured to provide a flat surface for contact with a caliper piston. In some embodiments, the radiating spacer and the backing plate are made from different metal materials having certain thermal conductivity coefficients to help promote advantageous heat distribution. ## Claims ### Claim 1 A radiating spacer for a brake pad, comprising: a plate body having a backing plate facing side and a caliper facing side; a plurality of cooling grooves in the backing plate facing side of the plate body, wherein each cooling groove of the plurality of cooling grooves extends only partially into the plate body; and a planar caliper piston contact area located on the caliper facing side of the plate body, wherein the planar caliper piston contact area is configured to provide a flat surface for contact with a caliper piston. ### Claim 2 (depends on 1) The radiating spacer of claim 1, wherein each cooling groove of the plurality of cooling grooves is a rounded U-shaped channel. ### Claim 3 (depends on 1) The radiating spacer of claim 1, wherein the plate body is steel-based or titanium-based. ### Claim 4 (depends on 1) The radiating spacer of claim 1, wherein the plate body is configured to be used on a plurality of different brake pads. ### Claim 5 (depends on 1) The radiating spacer of claim 1, wherein the plurality of cooling grooves covers 50% or more of the backing plate facing side of the plate body. ### Claim 6 (depends on 1) The radiating spacer of claim 1, wherein the flat surface of the planar caliper piston contact area covers a continuous 80% or more of the caliper facing side of the plate body. ### Claim 7 (depends on 1) A brake pad, comprising: the radiating spacer of claim 1; a backing plate coupled to the radiating spacer; and a friction pad coupled to the backing plate. ### Claim 8 (depends on 7) The brake pad of claim 7, wherein the backing plate is made from a first metal material and the plate body of the radiating spacer is made from a second metal material and the second metal material has a lower thermal conductivity coefficient than the first metal material. ### Claim 9 (depends on 8) The brake pad of claim 8, wherein the first metal material is steel-based and the second metal material is titanium-based. ### Claim 10 (depends on 7) The brake pad of claim 7, wherein the backing plate is coupled to the radiating spacer via a removable attachment. ### Claim 11 (depends on 7) The brake pad of claim 7, wherein a thickness of the plate body of the radiating spacer correlates with a corresponding loss of thickness in the friction pad. ### Claim 12 (depends on 7) A braking system, comprising: the brake pad of claim 7; and a caliper holding the brake pad, the caliper having a piston and the piston is configured to contact the planar piston contact area of the caliper facing side of the plate body of the radiating spacer. ### Claim 13 (depends on 12) The braking system of claim 12, wherein the caliper has a plurality of pistons and each piston of the plurality of pistons is configured to contact the planar piston contact area. ### Claim 14 A braking system, comprising: a brake pad comprising a radiating spacer, a backing plate coupled to the radiating spacer, and a friction pad coupled to the backing plate, wherein the radiating spacer has a plate body with a backing plate facing side and a caliper facing side, with a planar caliper piston contact area located on the caliper facing side, wherein the planar caliper piston contact area is a flat surface, wherein the backing plate includes one or more cooling grooves in the backing plate facing side of the plate body, wherein each cooling groove of the one or more cooling grooves extends only partially into the plate body; and a caliper holding the brake pad, the caliper having a piston and the piston is configured to contact the planar caliper piston contact area at the flat surface. ### Claim 15 (depends on 14) The braking system of claim 14, wherein the caliper has a plurality of pistons and each piston of the plurality of pistons is configured to contact the planar piston contact area.
