A method for detecting and measuring a clamping force and/or a braking torque includes encapsulating a fiber-optic strain sensor in a casing and incorporating the casing in a portion of friction material adhering to a base platform of a brake pad, detecting, by the fiber-optic strain sensor, a first strain in a first position of the casing along a first direction and a second strain in a second position of the friction material along a second direction, generating a first photonic signal, representative of the first detected strain, and a second photonic signal, representative of the second detected strain, receiving the first and second photonic signals, by an optical reading/interrogation unit, optically connected to the fiber-optic strain sensor, determining, by the optical reading/interrogation unit, the values of the first and second strains based on the first and second received photonic signals and determining a measurement of the clamping force and/or braking torque based on determined values of the first and second strains.
