Claim:
An elevator brake, comprising: a hoisting machine provided with at least a frame part and a traction sheave; a brake drum arranged to be rotatable with the traction sheave and provided with a braking surface; and a brake configured to provide a braking effect on the rotary motion of the traction sheave, said brake comprising at least one brake block provided with a braking surface, said brake block being arranged to act on the braking surface of the brake drum with a force directed substantially towards the braking surface, wherein the brake is provided with a first eccentric adjusting element and a second eccentric adjusting element, arranged on a first end and a second end of the brake, respectively, to adjust size of an air gap between the braking surface of the brake block and the braking surface of the brake drum, and wherein the second eccentric adjusting element at the second end of the brake is placed in a substantially loose through hole whose diameter is substantially larger than the diameter of the second eccentric adjusting element, and wherein a portion of the periphery of the substantially loose through hole which lies closer to the brake drum directly contacts and bears against the second eccentric adjusting element to form a stop face for the second eccentric adjusting element.
