Trailerbrake.question

Only my trailer hubs got wet. I didn't think it was as deep as it was because many trucks were in the dock before me and no one seemed concerned. Go figure. Anytime that I go to this customer and the dock is flooded, I use their tape measure and measure the water depth...if it is under the axle I'll back in.

 

yea, prob not a good idea to go deeper then hubs

 

When the brakes are warm and you have hot hubs from driving , don't back into water, firstly the immediate change in temperature from very hot too cold may crack your brake drums. and because the air inside the hub is hot the volume of air will be less then when the hub is cold . so when the hub cool down it practically generate a "low pressure" inside the hub. On oil hubs you get breathers on grease hubs it might suck some air in at the oil seal . You don't want wheel hubs to be submerged in water when brakes or hubs are cooling down . Make sure your hubs cooled down before entering the water, if possible. setting preloads on your hub regularly will keep the seals on the hub much more effective and when cold will and should keep water out.
