Air disc brakes

[Tanker]

They are a bit more pricey but you cant compare the performance and obviously maintenance is easier (no greasing, no adjusting for a start). We use them on majority of our 200 odd trailers and dollys here in Western Australia.. 120-171ton combinations and 45+ degree heat and they do the job day in day out no problems.. the only time we prefer drum is when going off road and onto serious corrugations. Anybody having overheating problems pulling 1 trailer is more than likely doing something wrong because it sure doesnt happen here. As for the whole "gotta remove the caliper to fix a wheel seal" thing, if you spec the right caliper, you can unbolt the hub from the disk thus leaving it behind making lighter work for yourself.. we rarely have that issue as we run grease in our hubs (besides on the truck) so im assuming most of you run oil?
