Electric brake effectiveness

Well, I didn't get back on here yesterday in part because I spent quite a bit of time out abusing my transmission and brakes. I made several stops and got the brake drums up to 450F according to my infrared thermometer. Old-Biscuit, thanks for link to the manual but there does seem to be one area where my telephone advice differed from the manual. The manual says to do gentle braking with plenty of cooling between each stop. The guy I talked with at Dexter said to heat the drums up past 300F. It's difficult to gauge from the driver's seat and I did overshoot a little. The brakes did get stinky which I assume was from out-gassing or burning off residual oil from the manufacturing process. They did seem to be noticeably improved though not yet where I need them to be. I had made several stops before without heating them up so much and did not notice any improvement but this is very subjective. I plan to try another round of stops today. I am just glad that I have not had to make any emergency stops yet and wish that I had known this from the get go. I might have been able to avoid a bad situation if I had known that the brakes needed this. Thanks for all of the wisdom shared here.
One more thing, I was surprised yesterday with how quickly the trailer brakes faded. Two moderatly hard stops seem to do them in. I don't anticipate making a lot of hard rapid fire stops in real life but coming off of a mountain might be a different story. I am hoping that it was due to outgassing as the brakes heated up and this too will be improved with use.
