For my 2004 Triton dual axle trailer, TR21X. Marine Master using UFP axles, DB 42 brakes and GOLD oil filled hubs, brakes on back axle only. Trailer tag has each axle labelled at 2250 lbs. Hubs have been flawless and I change 50 weight out every few years for maintenance. Flushed out brake fluid 6 years ago with new.
Over the winter I noticed leakage from one of my hubs, coming from the inner seal. At most, 1/4 of fluid leaked out over the 7 months it was parked so leak is not horrible but something I will fix asap. Inspection found about 8 feet of fishing line wrapped around it so I drained / refilled all four hubs with fresh 50 while I was in there.
I noticed too that my rotors need replacing, the inside face is grooved enough that I'd go below spec with a full rotor resurfacing. Also, I've also been thinking about going with four wheel brakes by adding a set to my front axle so now seems like a great time to do everything at once. New brakes, new inner seals, new bearings and new O-rings on hub pistons for all four wheels.
Questions I could use help with:
Seems folks are recommending swapping the DB42 calipers out and going with DB35 now. Is that the best route?
Will have to take wheel back off and look at min thickness stamp but pretty sure they're matching DB42 rotors. That of course dictates the bearing and seal size so I assume that I'll need to buy DB42 rotors and DB35 calipers / brackets to complete the conversion. Is that correct?
Do I need to order the stainless lip guard that the seal rides on, I expect marking and think a fresh seal would be best served with a fresh running surface. Sound right?
Lastly, I use Lucas Hub oil, doubt there is better but if there is, what would you recommend?
Thanks.
Hmmm, wonder too if I should add the brackets and shocks to my trailer..... Lol
