KNORR-BREMSE

An Introduction to Knorr Bremse Calipers

There are 3 popular brake types within the Knorr Bremse caliper range - SB, SN & SK. The SB
range was a 2 piece caliper which has evolved into the SN range. The SN range is now a one piece
calipers (or Monoblock). The SK is also a Monoblock caliper which is specially designed for trailer
applications with 22.5” wheels. The SN & SK calipers have been designed so that they replace the
early SB calipers. These rationalised calipers have reduced 1900+ OE fitted disc calipers to 116 part
numbers. These replacement calipers are not always fitted with the same components as used
on the original caliper, therefore it is vitally important to identify the caliper fitted when ordering
replacement parts.
