Coventry-based AP Racing is investing further in its break calliper production testing system, which will allow for increases in testing and production. The new unit, designed for high specification callipers, uses two stations to allow for the simultaneous testing of airflow and leakage.
An airflow test on the bleed nipple ports is carried out to check for blockages. To do this the cover is lowered to seal the calliper inside the test chamber and then a 3-stage pressure test, low, intermediate and high, is carried out.
The system can detect sticking pistons on a calliper at an early stage of production and features leak detection, which senses pressure changes within the vacuum chamber placed around the calliper. This is in contrast to the traditional pressure checks that analyse pressure changes within the feed line to the calliper.
AP Racing director of sales Norman Baker said: ‘This automated system has removed the bottleneck from the manufacturing process and we are now seeing an increase in the speed of production and testing.’
