The braking mechanism functions by imparting friction onto the string of a compound archery bow thereby preventing the string from moving or being wound out of or into a cam of the compound archery bow. ## Claims ### Claim 1 A compound archery bow, wherein said compound bow comprises: a bow riser having two limbs; a cam rotatably mounted on one of said limbs; a bowstring strung between said limbs, said bowstring being windably connected with said at least one cam; at least one string or cable(s) strung between said limbs, said at least one string or cable being windably connected with said at least one cam, wherein said bow is configured such that when a user draws said bowstring back the bowstring rotates said cam causing said string or cable to be wound out of said cam; and a brake comprising a brake actuation mechanism and a string friction mechanism, wherein said string friction mechanism is positioned on said string, wherein actuation of said brake actuation mechanism actuates said string friction mechanism to impart friction onto said string preventing said string from moving. ### Claim 2 (depends on 1) The compound archery bow of claim 1, wherein said string friction mechanism comprises a caliper comprising two opposing brake pads, wherein said caliper positioned such that said string is located between said two opposing brake pads of said caliper, wherein actuation of said brake actuation mechanism biases said opposing brake pads toward one another. ### Claim 3 (depends on 1) The compound archery bow of claim 1, wherein said brake actuation mechanism comprises a depressible lever handle. ### Claim 4 (depends on 3) The compound archery bow of claim 3, wherein said brake actuation mechanism is configured such that depression of said lever handle actuates said string friction mechanism. ### Claim 5 (depends on 3) The compound archer bow of claim 3, wherein said brake is configured such that said brake pads are biased toward one another in a biased position, wherein depression of said lever handle releases said brake pads from said biased position to release friction on said string. ### Claim 6 (depends on 1) The compound archery bow of claim 1, wherein said brake actuation mechanism is attached to said string friction mechanism by a hydraulic brake line. ### Claim 7 (depends on 1) The compound archery bow of claim 1, wherein said brake actuation mechanism is attached to said string friction mechanism by a mechanical brake line. ### Claim 8 (depends on 1) The compound archery bow of claim 1, wherein said brake actuation mechanism is attached to said string friction mechanism by an electrical connection. ### Claim 9 (depends on 1) The compound archery bow of claim 1, wherein said brake actuation mechanism is attached to said string friction mechanism by a wireless signal. ### Claim 10 (depends on 1) The compound archery bow of claim 1, wherein said string friction mechanism attached to said riser. ### Claim 11 (depends on 1) The compound archery bow of claim 1, wherein said string friction mechanism comprises a mounting attachment, wherein said mounting attachment is attached to said riser. ### Claim 12 (depends on 1) The compound archery bow of claim 1, wherein said brake actuation mechanism is a depressible trigger. ### Claim 13 (depends on 1) The compound archery bow of claim 1 wherein said bow handle comprises a grip section, wherein said brake actuation mechanism is attached to said bow riser proximate to said grip. ### Claim 14 (depends on 13) The compound archery bow of claim 13, wherein said brake actuation mechanism comprises a depressible lever, wherein said depressible lever is positioned on said bow handle on an opposite side of said bow handle from said bowstring. ### Claim 15 (depends on 14) The compound archery bow of claim 14, wherein said lever is biased away from said bow handle, wherein depression of said lever toward said bow handle actuates said cable friction mechanism to impart friction on said string. ### Claim 16 (depends on 14) The compound archery bow of claim 14, wherein said lever is biased away from said bow handle, wherein depression of said lever toward said bow handle releases said string friction mechanism from imparting friction on said string. ### Claim 17 A compound archery bow, wherein said compound archery bow comprises: a bow riser having two limbs; a cam rotatably mounted on one of said limbs; a bowstring strung between said limbs, said bowstring being windably connected with said at least one cam; at least one string or cable strung between said limbs, said at least one string or cable being windably connected with said at least one cam, wherein said bow is configured such that when a user draws said bowstring back the bowstring rotates said cam causing said cable to be wound out of said cam; and a brake comprising a brake caliper and an actuation device configured to actuate said caliper, wherein said caliper comprising two opposing brake pads, wherein said caliper positioned such that said string is located between said two opposing brake pads of said caliper, wherein actuation of said brake actuation mechanism biases said opposing brake pads toward one another to impact friction on opposite sides of said string. ### Claim 18 (depends on 17) The compound archery bow of claim 17, wherein said actuation device comprises a depressible brake lever. ### Claim 19 (depends on 18) The compound archery bow of claim 18, wherein said depressible brake lever is configured such that depressing said brake lever biases said brake pads of said brake caliper together to impart friction on said string.
