The invention relates to a brake assembly (100; 200; 300), comprising: a caliper comprising a brake cylinder (5) formed in one piece with an outer clamping portion (6), the brake cylinder (5) defining an axial direction (9) and the outer clamping portion (6) forming a pair of outer clamping fingers (6a, 6b) and a recess (7) formed in between the outer clamping fingers (6a, 6b); a brake piston (12) received in the brake cylinder (5) and configured to move axially with respect to the brake cylinder (5); and an inner brake pad assembly (4a) and an outer brake pad assembly (4b), the inner brake pad assembly (4a) and the outer brake pad assembly (4b) disposed axially in between the brake piston (12) and the outer clamping portion (6), wherein the pair of outer clamping fingers (6a, 6b) of the outer clamping portion (6) define a pair of outer clamping surfaces (18a, 18b) facing the brake piston (12), the outer clamping portion (6) configured to exert a clamping force on the outer brake pad assembly (4b) by means of the outer clamping surfaces (18a, 18b). A clamping portion (16) for exerting a clamping force on the inner brake pad assembly (4a) may protrude out of the brake cylinder (5) and extend fully or at least partially laterally outward from the brake piston (12).
Alternatively, a maximum lateral extension of the brake piston (12) may be equal to or larger than a maximum lateral extension of the pair of outer clamping surfaces (18a, 18b), wherein the inner clamping portion (16) extends fully or at least partially laterally inward from the brake piston (12).
