A brake pad adapter plate 2 has a rear surface having a mounting bracket provided thereon by means of which, in use, the adapter plate 2 is attached to a braking arm 5 of a braking system. A front surface has a dovetail groove 15 extending longitudinally therealong from the bottom end 2b of the plate 2 towards but terminating short of the top end 2a, by means of which, in use, a friction material 3 having a complementary dovetail tongue formed on a fastening surface thereon is attached to said front surface. A through openi ng 16 is formed in the adapter plate 2 proximate to the bottom end 2b and extending from rear surface to the front surface intersecting the dovetail groove 15, and a locking plate 20 is mounted on the rear surface so as to engage in said through opening 15. The locking plate 20 is moveable between an extended position in which the locking plate 20 extends into the dovetail groove 15 a nd a retracted position in which the locking plate 20 is withdrawn from the dovetail groove 15, and a spring clip 21 is associated with locking plate to restrain the locking plate 20 the extended or retracted position.
