TRP DISC BRAKE ROTORS FMVSS 121 TEST TEST PARAMETERS The test was performed by Link Manufacturing, an independent testing facility based in the US. The FMVSS 121 test was performed to Gross Axle Weight Rating (GAWR) 26,000 lb ensuring that the rotor was tested to the most extreme application possible. TRP®Rotor tested TRPDR006 - SUITS SAF INTRADISC 377MM 10 STUD, 285 PCD Tested to 26,000 lb Gross Axle Weight (Heavy duty application) Disc Pad used was TRP®Disc Pad 1536935 (HD Pad) Air Chamber – Type 24” 0.6 TEST PARAMETERS The test was performed by Link Manufacturing, an independent testing facility based in the US.

It verifies that the rotors can dissipate heat efficiently within a set criteria. Australian and New Zealand vehicle standards are for the fully dressed axle, so it is important that we use a recognised standard like FMVSS 121 to test the performance of the rotor. WHAT IS FMVSS 121 STANDARD? FMVSS 121 stands for Federal Motor Vehicle Safety Standard 121 and tests whether a given rotor has sufficient heat dissipation characteristics to pass the set test requirements. TRUSTED . RELIABLE .

TESTING PROCEDURE ▌ 7 stops made at 20, 30, 40, 50, 60, 70 and 80 PSI. ▌ Stops are made from 80 kph to 0 kph. ▌ Average torque is measured during each stop to calculate a retardation ratio which has to be above the legal limit at each pressure.
