A brake assembly for a height-adjustable walker apparatus is provided. The brake assembly includes a brake actuator, a wheel-engaging brake member and a brake cable assembly. The brake cable assembly includes a flexible, inner cable. The brake cable assembly includes a flexible, outer casing through which the inner cable extends and is moveable relative to. The inner cable has a first end coupled to the brake actuator and a second end coupled to the wheel-engaging brake member. The brake assembly includes a brake cable housing shaped to enclose a slack portion of the brake cable assembly.

1. A walker apparatus, comprising: a height-adjustable assembly;at least one elongate side member coupled to and extending outwards from the height-adjustable assembly;a brake cable assembly primarily extending along the height-adjustable assembly; anda brake cable housing abutting, extending along, and receiving a portion of at least one of the height-adjustable assembly and said elongate side member, a slack portion of the brake cable assembly being enclosed by the brake cable housing, wherein the brake cable housing abuts and extends along both the height-adjustable assembly and the at least one elongate side member. 2. A walker apparatus comprising: a height-adjustable assembly;at least one elongate side member coupled to and extending outwards from the height-adjustable assembly;a brake cable assembly primarily extending along the height-adjustable assembly; anda brake cable housing abutting, extending along, and receiving a portion of at least one of the height-adjustable assembly and said elongate side member, a slack portion of the brake cable assembly being enclosed by the brake cable housing, wherein the brake cable housing comprises a rear side having an upper passageway shaped to receive the slack portion of the brake cable assembly extending from a lower end of a brake cable assembly, anda lower passageway shaped to receive the slack portion of the brake cable assembly extending from a brake actuator of the walker apparatus. 3. The walker apparatus as claimed in claim 2, wherein the slack portion of the brake cable assembly is loop-shaped. 4. The walker apparatus as claimed in claim 2, wherein the brake cable housing includes a chamber which extends between and is in communication with said passageways. 5. The walker apparatus as claimed in claim 4, wherein the upper passageway is downwardly concave in shape and wherein the lower passageway is upwardly concave in shape. 6. The walker apparatus as claimed in claim 4, wherein the chamber is concave in shape in a direction facing the upper passageway and the lower passageway. 7. The walker apparatus as claimed in claim 4, wherein the chamber is larger than the upper passageway and larger the lower passageway. 8. The walker apparatus as claimed in claim 4, wherein the upper passageway and the lower passageway have cross-sectional widths, the cross-sectional widths of the upper passageway and the lower passageway increasing in a direction extending from the height-adjustable assembly and towards the chamber. 9. The walker apparatus as claimed in claim 2, wherein the housing has an interior space that is generally crescent-shaped. 10. The walker apparatus as claimed in claim 2, wherein the height-adjustable assembly has an aperture interposed between a lower end and an upper end of the height-adjustable assembly, the slack portion of the brake cable assembly extending through said aperture of the height-adjustable assembly, and wherein the brake cable housing couples to and extends outwards from the height-adjustable assembly. 11. The walker apparatus as claimed in claim 2, wherein the walker apparatus has a front, and wherein the height-adjustable assembly has an aperture through which the slack portion of the brake cable assembly extends, the aperture of the height-adjustable assembly being slot-shaped and facing the front of the walker apparatus. 12. The walker apparatus as claimed in claim 2, wherein the height-adjustable assembly includes a pair of telescoping tubes and wherein the brake cable housing extends along and is shaped to abut a portion of one of said tubes. 13. The walker apparatus as claimed in claim 2, wherein the brake cable housing includes a peripheral edge portion that is u-shaped in cross-section and abuts said at least one of the height-adjustable assembly and the elongate side member via said peripheral edge portion. 14. The walker apparatus as claimed in claim 2, wherein the height-adjustable assembly includes a lower elongate member and an upper elongate member shaped to fit within the lower elongate member, and wherein excess portions of the brake cable assembly enter and exit the brake cable housing at locations below the upper elongate member of the height-adjustable assembly. 15. The walker apparatus as claimed in claim 2, wherein the brake cable assembly abuts an outer peripheral edge of an inner portion of the housing when the walker apparatus is in an extended position and the brake cable assembly abuts an inner peripheral edge of an outer portion of the housing when the walker apparatus is in a retracted position. 16. The walker apparatus as claimed in claim 15, wherein the inner peripheral edge of the outer portion of the housing is inwardly concave and the outer peripheral edge of the inner portion of the housing is outwardly convex. 17. A walker apparatus comprising: a height-adjustable assembly of elongate members, the height-adjustable assembly having an upper end, a lower end spaced-apart from the upper end, and an aperture interposed between the upper end and the lower end thereof;a brake actuator operatively coupled to the upper end of the height-adjustable assembly;a brake member operatively coupled to the lower end of the height-adjustable assembly;a pair of spaced-apart elongate side members coupled to and extending laterally-outwards from the height-adjustable assembly;a brake cable housing operatively connecting to the height-adjustable assembly at a location between the brake actuator and the brake member, the brake cable housing being interposed between said side members and including an upper peripheral edge portion and a lower peripheral edge portion, the upper peripheral edge portion and the lower peripheral edge portion of the brake cable housing being u-shaped in cross-section and being shaped to abut with and receive respective ones of said side members for coupling to the walker apparatus thereby; anda brake cable assembly including a flexible, inner cable and a flexible, outer casing through which the inner cable extends and is moveable relative thereto, the inner cable having a first end operatively connected to the brake actuator and a second end operatively connected to the brake member, the brake cable assembly being primarily enclosed within the height-adjustable assembly with a slack portion of the brake cable assembly extending through the aperture of the height-adjustable assembly and being enclosed within the brake cable housing.
