1. A disc brake comprising: a) a support bracket including: i. a pair of spaced apart frame members at opposite ends of the support bracket;ii. at least two arms extending from each of the frame members; andiii. an opening in each of the arms;b) an inner brake shoe that includes a leading projection
1. A disc brake comprising: a) a support bracket including: i. a pair of spaced apart frame members at opposite ends of the support bracket;ii. at least two arms extending from each of the frame members; andiii. an opening in each of the arms;b) an inner brake shoe that includes a leading projection with an opening and a trailing projection with an opening on opposite ends of the brake shoe;c) an outer brake shoe that includes a leading projection with an opening and a trailing projection with an opening on opposite ends of the brake shoe;d) a leading slide pin;e) a trailing slide pin;f) the leading slide pin and the trailing slide pin are opposing and engage with the respective openings in the at least two arms and the openings in the projections of the brake shoes so that the brake shoes are supported by the two opposing slide pins and the two opposing slide pins are supported by the at least two arms;g) a slidable piston operable to cause the inner and outer brake shoes to move towards one another; andh) a caliper body including a single pair of spaced apart boss portions, located near the slidable piston, that include an opening with a bushing for receiving the slide pins; wherein the caliper body is supported on the slide pins by the single pair of spaced apart boss portions so that the caliper body is only supported on the slide pins by the single pair of spaced apart boss portions. 2. The disc brake of claim 1, wherein a leading end of one or more of the brake shoes is pulled into contact with the leading slide pin and causes the leading slide, pin, the frame member in which it engages, or both to deflect so that a trailing end of the one or more brake shoes is pushed into contact with the trailing slide pin. 3. The disc brake of claim 2, wherein the disc brake is configured to operate in pull abutment mode, thereby, reducing the tendency to self-apply, and the reduction in self-apply reduces squeal, taper wear, or both. 4. The disc brake of claim 1, wherein the inner brake shoe, outer brake shoe, or both include a first engagement portion, and the caliper body includes a second engagement portion. 5. The disc brake of claim 4, further includes a clip for securing the first engagement portion to the second engagement portion. 6. The disc brake of claim 5, wherein the bushing includes grooves. 7. The disc brake of claim 6, wherein the disc brake is configured to operate in pull abutment mode, thereby, reducing the tendency to self-apply, and the reduction in self apply reduces squeal, taper wear, or both. 8. The disc brake of claim 1, wherein the support bracket does not include an outer support tie bar. 9. The disc brake of claim 1, wherein the pair of spaced apart boss portions are separately formed and secured to the caliper body. 10. The disc brake of claim 1, wherein each of the at least two arms extending from the frame members include: a) an outboard arm located in an outboard position, andb) an inboard arm located in an inboard position,wherein the outboard arm and the inboard arm are separated by a spacing therebetween. 11. A disc brake comprising: a) a support bracket including: i. a pair of spaced apart frame members at opposite ends of the support bracket;ii. three arms extending from each the frame members; andiii. an opening in each of the arms;b) an inner brake shoe that includes a leading projection with an opening and a trailing projection with an opening on opposite ends of the brake shoe;c) an outer brake shoe that includes a leading projection with an opening and a trailing projection with an opening on opposite ends of the brake shoe;d) a leading slide pin;e) a trailing slide pin;f) the leading slide pin and the trailing slide pin are opposing and engage with the respective openings in the three arms and the openings in the projections of the brake shoes so that the brake shoes are supported by the two opposing slide pins and the two opposing slide pins are supported by the three arms;g) a slidable piston operable to cause the inner and outer brake shoes to move towards one anotherh) a caliper body including a single pair of spaced apart boss portions, located near the slidable piston, that include an opening with a bushing for receiving the slide pins; wherein the caliper body is supported on the slide pins by the single pair of spaced apart boss portions so that the caliper body is only supported on the slide pins by the single pair of spaced apart boss portions. 12. The disc brake of claim 11, wherein a leading end of the one or more brake shoes is pulled into contact with the leading slide pin and causes the leading slide pin, the frame member in which it engages, or both to deflect so that a trailing end of the one or more brake shoes is pushed into contact with the trailing slide pin. 13. The disc brake of claim 11, wherein the inner brake shoe, outer brake shoe, or both, include a first engagement portion, the caliper body includes a second engagement portion. 14. The disc brake of claim 13, further includes a clip for securing the first engagement portion to the second engagement portion. 15. The disc brake of claim 13, wherein the bushing includes grooves. 16. The disc brake of claim 15, wherein the disc brake is configured to operate in pull abutment mode, thereby, reducing the tendency to self-apply, and the reduction in self apply reduces squeal, taper wear, or both. 17. The disc brake of claim 13, wherein the disc brake is configured to operate in pull abutment mode, thereby, reducing the tendency, to self-apply, and the reduction in self-apply reduces squeal, taper wear, or both. 18. The disc brake of claim 11, wherein the support bracket does not include an outer support tie bar. 19. The disc brake of claim 11, wherein the pair of spaced apart boss portions are separately formed and secured to the caliper body. 20. The disc brake of claim 11, wherein the three arms extending from each of the frame members include: c) an outboard arm located in an outboard position,d) an inboard arm located in an inboard position, ande) a central arm located in a central position between the outboard arm and the inboard arm,wherein the outboard arm, the central arm, and the inboard arm are separated by a spacing therebetween each respective arm.
