Noise Resistance - AK Master

A K Master- Brake Pad Noise Resistance

A K Master is the test programme used by the OEM brake industry to measure and develop brake pads for OE use and assesses their performance at the more extreme values of braking performance not covered by the ECE R90 test regime.

Test used by the OE industry to evaluate products -
“Green” performance

A K Noise (SAE2521)

In tests Juratek pads are up to 24% quieter than the leading aftermarket suppliers

All of our brake pads are fitted with anti-noise shims. These shims are a specially developed Rubber - Steel - Rubber "sandwich" and help prevent unwanted brake noise in-service.

The effectiveness of our premium anti – noise brake shims is assured by tests we carry out to SAE2521 – the test developed by the OEM automotive industry to measure the noise performance of a vehicle braking system.

Carried out on a test rig comprising a full vehicle “corner” – brake calliper, disc, suspension arm etc.

Complete rig contained in an anechoic chamber to prevent external noise “pollution”.

Special test sequence (matrix) totalling 1462 brake applications  comprising stops.
0 – 30 bar pressure
50 – 300 deg c
3 – 80 kph
