Wheel Cylinder repair kit opinions

[RCN]

Had a look at my brakes the other day and the day and the N?S?R whell clyinder looks like it might be getting the smallest of leaks at the cylinder. Normally would opt just to replace both and carry on , but i was talking to a co-worker about throw away society and remembered i used to as an apprentice fit rebuild kits to these. So had a look and found these:

Anyone use these or re build their cylinders anymore, or am i just being nostalgic and showing my age?

Not me, rear wheel cylinders are cheap enough new and brakes are more important today on our busy roads than ever I would not risk brake parts from an unknown source.

£11.50 at eurocar parts, they had 33% off at the weekend and do most weekends so £7.70 each your seal kit is £4.99
and does not come with a new bleed nipple.
