brake block maintenance

On contemporary Ambassadeurs, should the shafts on which the brake blocks slide be lubricated? What about the race for the brake blocks in the side plate? Thanks.

I don't know if its right or wrong, but I apply a drop of TSI321 then wipe off.

Both the post and the race, Bryan?

yes, both post and the race (ring).

The posts need to be clean so the blocks can traverse freely. The cast control ring needs to be clean also. While it is a controlled friction surface, any corrosion will unduly impede spool rotation.

The cast control ring should not be lubricated as doing so will modify it's performance characteristics requiring re-tuning of the cast control mechanism. Not sure how much impact TSI would have though.

The system is designed to be operated without lubrication --------clean, dry.

Best,

Thanks, guys.

Sometimes the mechanism can develop some "howl" or squeaks and then the race can be cleaned with a penetrating oil (ie corrosion-x or tsi). Same for the posts that the brakes ride on.

Remnants of the oil are quickly gone from the race due to the scrubbing nature of the brakes and it returns to "clean and dry" function very quickly.

I buy the "run it dry" approach. It is probably the simplest way to achieve a known coefficient of friction, at least on a reel in the right condition. But here's something interesting: Shimano wants oil on the brake blocks of their round reels: http://fish.shimano.com/content/sac-fish/en/home/customer-service/reel-maintenance-instructions/_jcr_content/bodycontent/download_1/downloadFile/file.res/Maintenance%20Tips-%20Round%20Baitcasting%20Reels%20.pdf

What it does is clean the race when you cast the reel. The oil is soon gone.
