MORE THAN two million BPW ECO Disc brakes have been produced and it remains one of the most widely sold trailer disc brakes in Europe. Its success is due to the fact that BPW’s ECO Disc caliper was designed from the ground up to specifically meet the requirements of the trailer. Disc brake calipers had previously derived from truck disc brakes. The next logical step is BPW’s new disc brake, the TS2. It retains the robust features of the original ECO Disc brake caliper but TS2 is 12kg lighter.
