A braking system for a stroller includes: a brake pedal positioned near a first rear wheel of the stroller; a braking cam operationally coupled to the brake pedal and rotatable around a pivot point from a first position to a second position; and a brake lever having a first end configured to contact the braking cam when the braking cam is in the second position, and a second end having a plurality of teeth configured to engage at least one gear driven by the first rear wheel of the stroller when the braking cam is in the second position. A depression of the brake pedal causes the braking cam to rotate around the pivot point from the first position to the second position, thereby causing the teeth of the brake lever to engage the at least one gear to prevent rotation of the first rear wheel.

1. A braking system for a stroller comprising: a single brake pedal positioned near a first rear wheel of the stroller;a braking cam operationally coupled to the brake pedal and rotatable around a pivot point from a first position to a second position; anda brake lever having a first end configured to contact the braking cam when the braking cam is in the second position and a second end having a plurality of teeth configured to engage at least one gear driven by the first rear wheel of the stroller when the braking cam is in the second position,wherein a first depression of the brake pedal causes the braking cam to rotate around the pivot point from the first position to the second position, thereby causing the teeth of the brake lever to engage the at least one gear to prevent rotation of the first rear wheel, and a second depression of the brake pedal causes the braking cam to rotate around the pivot point from the second position to the first position, thereby causing the teeth of the brake lever to disengage the at least one gear to allow rotation of the first wheel, andwherein the braking cam and the brake pedal are separate components. 2. The braking system of claim 1, wherein a second rear wheel comprises a braking device that is operationally coupled to the brake pedal positioned near the first rear wheel of the stroller. 3. The braking system of claim 2, wherein the first depression of the brake pedal causes actuation of the braking device of the second rear wheel, thereby preventing rotation of the second rear wheel. 4. The braking system of claim 2, wherein the second depression of the brake pedal releases the braking device of the second rear wheel, thereby allowing rotation of the second rear wheel. 5. The braking system of claim 2, wherein the braking device of the second rear wheel is operationally coupled to the brake pedal by a cable. 6. The braking system of claim 1, wherein the braking cam has a modified elliptical shape. 7. A method of braking a stroller comprising: providing a braking system for a stroller comprising: a single brake pedal positioned near a first rear wheel of the stroller;a braking cam operationally coupled to the brake pedal and rotatable around a pivot point from a first position to a second position; anda brake lever having a first end configured to contact the braking cam when the braking cam is in the second position and a second end having a plurality of teeth configured to engage at least one gear driven by the first rear wheel of the stroller when the braking cam is in the second position; anddepressing the brake pedal to cause the braking cam to rotate around the pivot point from the first position to the second position, thereby causing the teeth of the brake lever to engage the at least one gear to prevent rotation of the first rear wheel; anddepressing the brake pedal a second time to cause the braking cam to rotate around the pivot point from the second position to the first position, thereby causing the teeth of the brake lever to disengage the at least one gear to allow rotation of the first rear wheel. 8. The method of claim 7, wherein the braking system further comprises a braking device provided on a second rear wheel and operationally coupled to the brake pedal positioned near the first rear wheel of the stroller. 9. The method of claim 8, wherein the depression of the brake pedal causes actuation of the braking device of the second rear wheel, thereby preventing rotation of the second rear wheel. 10. The method of claim 8, wherein a second depression of the brake pedal releases the braking device of the second rear wheel, thereby allowing rotation of the second rear wheel. 11. The method of claim 8, wherein the braking device of the second rear wheel is operationally coupled to the brake pedal by a cable. 12. The method of claim 7, wherein the braking cam has a modified elliptical shape. 13. A braking system for a stroller comprising: a single brake pedal;a braking cam operationally coupled to the brake pedal and rotatable around a pivot point from a first position to a second position; anda brake lever having a first end configured to contact the braking cam when the braking cam is in the second position and a second end configured to prevent rotation of at least one wheel of the stroller when the braking cam is in the second position,wherein a first depression of the brake pedal causes the braking cam to rotate around the pivot point from the first position to the second position, thereby causing the second end of the brake lever to prevent rotation of the first rear wheel, and a second depression of the brake pedal causes the braking cam to rotate around the pivot point from the second position to the first position, thereby causing the second end of the brake lever to allow rotation of the first rear wheel. 14. The braking system of claim 13, wherein the braking cam has a modified elliptical shape. 15. The braking system of claim 13, wherein the second end of the brake lever comprises a plurality of teeth. 16. The braking system of claim 15, wherein the plurality of teeth are configured to engage at least one gear driven by the at least one wheel of the stroller when the braking cam is in the second position.
