The first sliding block connects to a rear brake line of a bicycle. The second sliding block connects to a front brake line of the bicycle. The first sliding block moves to brake a rear wheel of the bicycle, and then the first sliding block drives the second sliding block to move and thereby brake the front wheel of the bicycle. The brake distribution structure ensures that the rear wheel is always braked first, prevents brake lockup, reduces hazards otherwise arising from manmade false action, and maximizes rider safety. ## Claims ### Claim 1 A brake distribution structure, comprising: a first sliding block having a first top surface, a first bottom surface, a first sliding surface, a first lateral surface, at least a manual brake connecting portion, a first connecting portion, and at least a driving bump rising from the first sliding surface; a second sliding block having a second top surface, a second bottom surface, a second sliding surface, a second lateral surface, a second connecting portion, and at least a driving slot exposed from the second sliding surface, wherein the second sliding surface is in slidable contact with the first sliding surface, and the driving slot is of a larger length than the driving bump; and a tube for receiving the first sliding block and the second sliding block in a manner to allow the first sliding block and the second sliding block to slide within the tube, wherein two ends of the tube have a first covering surface and a second covering surface, respectively, and at least an opening is disposed on each of the first covering surface and the second covering surface, wherein the driving slot is coupled to the driving bump in a one-to-one relationship, such that displacement of the driving bump drives the second sliding block to move. ### Claim 2 (depends on 1) The brake distribution structure of claim 1, wherein the manual brake connecting portion is a slot exposed from the first top surface and the first lateral surface. ### Claim 3 (depends on 1) The brake distribution structure of claim 1, wherein the first connecting portion is a slot exposed from the first bottom surface and the first lateral surface, and the first connecting portion is not in contact with the manual brake connecting portion. ### Claim 4 (depends on 1) The brake distribution structure of claim 1, wherein the second connecting portion is a slot exposed from the second bottom surface and the second lateral surface. ### Claim 5 (depends on 1) The brake distribution structure of claim 1, wherein the driving bump has a receiving recess for fixing therein a buffer unit in place. ### Claim 6 (depends on 1) The brake distribution structure of claim 1, wherein the first covering surface is a covering body coupled to the tube by means of threads. ### Claim 7 (depends on 6) The brake distribution structure of claim 6, wherein a movable guider is disposed between the tube and the covering body. ### Claim 8 (depends on 1) The brake distribution structure of claim 1, wherein the first covering surface is a stationary guider. ### Claim 9 (depends on 1) The brake distribution structure of claim 1, wherein at least a rail and at least a groove are disposed between the first sliding surface and the second sliding surface. ### Claim 10 (depends on 1) The brake distribution structure of claim 1, wherein the first sliding block is heavier than the second sliding block. ### Claim 11 (depends on 1) The brake distribution structure of claim 1, wherein the first sliding block is one of a hemicylinder and a polygonal cylinder. ### Claim 12 (depends on 1) The brake distribution structure of claim 1, wherein the second sliding block is one of a hemicylinder and a polygonal cylinder.
