rear calliper slider pin?

[mike5100]

Both rear callipers were seized on my 2009 400H.  The independent garage fitted new disks and pads for me and said they got the old callipers unseized.  However, after picking up the car I realised that both rear brakes were slightly binding during normal driving (temperature after shortish runs about 100degC whereas front about 25 deg C).  They have taken the slider pins out a couple of times now and cleaned and regreased them, but say they cannot get replacement pins without ordering genuine Lexus 'carriers'.  Does this sound likely?  If not, does anyone know how or where I could simply order two new slider pins for the callipers?

Thanks

Maybe the caliper holes for the pins itself needs reaming ???

Maybe I'm going to display my lack of understanding of the way brakes are put together, but wouldn't the new pads be the things that had the holes in?  ie the shoes would slide along the pin or pins .... or do the callipers slide along some other pin?

The calipers hold the pads, The pins guide the calipers from standing to compression and back to standing, There are no holes in the pads that the pins go through.
