New master cylinder question

[lfhoward]

I recently replaced the master cylinder and rehabbed the surge brakes on my M116A3 using parts from Croft Trailer Supply. Everything was a direct swap.

The trailer rides amazingly well with rebuilt brakes and new bearings.

New master cylinder and other brake parts installed.

The master cylinder exterior rusted after only a couple of days in the elements. Should I have painted it prior to installation? Will the surface rust be an issue down the road? Suggestions welcome.

The rust will not be a problem.
Just keep the cap seal area clean and it will fine.

It would have been easier to have painted it before install, but nothing to worry about.

Croft is an excellent company.
