Just for others who may consider a big brake upgrade. I had the testing done by Mark Dewhurst Engineering and with a compliance certificate in hand. A bit rusty on the details but if a similar vehicle has been complianced it can be used for others. If anyone needs it, I have the compliance cert. it had virtually no fade despite repeated runs fully loaded…although it does take a long time to run up to testing speed!
