    I need to learn about these.

    I am used to the style in which you drill/drive out two brass rivets, replace the lining and squeeze/set 2 new rivets which go right through the lining.

    I am told these ones I am looking at are called ‘rivetless’.
    The linings do not have a hole all the way through. They have 2 depressions which accept a flat rivet head. The rivet head sits above the inner surface where the lining seats, and holds the lining in position.

    Are these rivets removable?
    Are they removed each lining replacement or only if damaged, or never - if damaged replace that entire part.

    Thanks for any info.

    just for the record, these are horrid!
    the lining mounts do not hold the linings securely so they are always falling off during reassembly. And; you must take care that one has not slipped off a rivet when tightening down (and this is not real easy to see).
    A swollen rivet head makes reassembly difficult-> impossible.
    Overall I can see spending a bunch more time re-lining.

    I work in a shop where mostly 400 series Cessna are, that's about all I see, no problem working on them, it's probably a matter of more experience required and it will be much easier to maintain that type of brake, it's faster to replace the clip on than drilling out and re riveting the rivet on style

    Plus, you get a lot less material on each lining.
    Will be watching service life closely.

    I haven’t seen any notable difference in service life.
