High temp capability of Mystik hi-temp red

[Stewart Fan]

I use Mystik JT6 hi-temp red grease for the hubs (with disc brakes) on my boat trailer.

I had an issue with two calipers hanging up last week. One hub was at about 180° the other was about 200°. Normal is about 125.

This all happened in about 3 miles from the house to the gas station,so they weren't at these temps for a prolonged period.

The grease currently in the hubs is from a fresh re-pack about a month ago.

The Mystik grease has a dropping point of 550° and a working range of -10° to 325°.

The brakes are fixed,and I'm wondering if the grease in the hubs is fine or I need to re-pack?

From the specs on the grease I was well under any danger zone.

That's a little hot, but if nothing was smoking, I'd say you're fine.

does the boat trailer hub gets into the water during boat launching/loading?

when in doubt: always spend the time repacking the bearings with fresh clean grease.

There! Now you can rest easy.
