Knorr-Bremse diagnostic unit K154433N50
The Knorr-Bremse Potentiometer Tester serves;
- To test the Potentiometer function on
Knorr-Bremse disc brakes
- To check the wear condition of the brake pads
and brake discs
5.1.11 The Tester can be used on all current Knorr-Bremse
brake types with continues or black/white Potentiometer.
Note:
Knorr-Bremse recommends that before replacing a brake
caliper with a suspected potentiometer failure, that it first be tested
using the Potentiometer Tester. If no defect is found, the cause is not
with the brake caliper and therefore does not need replacing.
