Brakes not clunking

[Mulligan]

Hi all, just looking for some advice.
I have a 1960 Avion H24, with 12" electric brakes, I've put new shoes and magnets on, and they are working fine, i use the Tekonsha Prodigy RF controller to keep within the law in UK. when i first installed new parts i did a direct 12v from battery to test and got the familiar "clunk" when the magnets pull onto the hub. but now when using i dont ever hear the clunk even when testing breakaway device. Is this ok ? brakes are working fine with the TV and I've even used the boost button and used the trailer to stop the TV and all is ok, as you can imagine theres not many in the uk with electors brake let alone with a 55 year old trailer!!! so can some kind soul chip in with some knowledge.
Cheers
Tim
Ps they don't seem to be binding, aft a 100+ mile journey they were only slightly warm to the touch

The brakes are self adjusting and the clunk was due to too much free movement in the system when new. Now they do not have as far to go and engage smoothly.

Also... when you energize directly with 12 VDC, there is a lot of current draw so you will get the 'slam' of the brake magnet. When running your brake controller, it varies the power applied so you will get smoother contacting.

If you pull the 'breakaway' switch you should get full, instant engagement of all brake magnets... and a possible 'clunk'..
