hi all..

like other B310 around
i think the safety belt same for the dats around the world?

mine got written something like 'brimat' or something... aid its auto-retract type (not the fixed type in B110)


the thing is i feel the button is a bit tight
so i spray a bit WD40 into it

then now the problem come

sometimes during driving...
the belit will automatically comes off.. due to pulling..

if i clip it and pull real hart with my hand.. it will come off also.. :(

why is it.. unsafe after i use WD40?
anyone have similar experience?
is there any way to make it safe again...?


thanks in advance for opinion and suggestions.
