An elevator safety brake (300) for use in an elevator system, the safety brake (300) comprising: a safety block (310) substantially made of a polymeric material or a polymer-based composite material. The safety block (310) comprising: an elongate channel (320) defining a channel axis (325), wherein the elongate channel (320) is for receiving an elevator guide rail (330) of the elevator system when in use; and a cavity (340). The safety brake (300) further comprises a first braking component (250, 350) housed in the cavity (340), wherein the first braking component (250, 350) comprises a body (360) and a first braking surface (370). The safety brake (300) further comprises a second braking component (380) comprising a second braking surface (390). The first braking component (250, 350) is arranged on one side of the elongate channel (320) and the second braking component (380) is arranged on the other side of the elongate channel (320). The first braking component (250, 350) is arranged to move between a first position (A) and a second position (B) in a direction generally parallel to the channel axis. When the first braking component (250, 350) is in the first position (A), the first braking surface (370) and the second braking surface (390) define a first separation distance (Di), and when the first braking component (250, 350) is in the second position (B), the first braking surface (370) and the second braking surface (390) define a second separation distance (D2), wherein the second separation distance (D2) is smaller than the first separation distance (Di).
