3320 x 1 set of 4 pcs. XK150 EARLY DUNLOP DESIGN DISC BRAKE with Round Brake Friction Pads (Set of 4). This was the first design of disc brake, developed from an Aeronautical system and fitted directly to the C-Type in the 4-pad version of a caliper. Scaled down and used as a 2 piece, bolt on piston unit version on XK150 early models

Pads are glued in place onto the winged plate and then a single screw is inserted through the countersunk hole in the back (with wear-indicator pins fitted through the cast body). When the glue and screw break free, the pad can then spin in the carrier, losing braking efficiency.

NOTE : Upgrading to the later spec. XK150 'quick-fit' system with square pad is a good modification for improved performance. (SEE : 3428 )
