I am just wanting to know if I should spray the caliper with Lanox before submersion each time and wash down with fresh water afterwards to extend the life of the new brakes beyond the previous 2 years. The trailer guy recommended waiting until the brakes cool and also turning off the brake controller before submersion. Would you guys agree with this advice in order to minimise corrosion? I realise there is a risk of losing traction on a slippery ramp, but I normally launch from MBTBC ramp which is well maintained and has good grip for my BT50 4x4.
