A brake pad assembly (300) comprises a brake pad (302) having a braking surface (306) and an opposed back surface (308), a hydraulic actuator comprising a cylinder (310) and a piston (312), the piston being operatively connected to the back surface of the brake pad and moveable within said cylinder for varying the position of the brake pad and a conduit extending through said piston and being in fluid communication with said braking surface for providing fluid flow to said braking surface. The brake pad (302) comprises a passage (324) extending from the back surface (308) to the braking surface (306) for providing fluid flow to said braking surface, said passage having one or more internal walls (323) and means for preventing or reducing the leakage of fluid from said passage into said brake pad (302) via said one or more internal walls |
