I use EBC HH in front.
Rear ?????
As said if brakes are working fine then you can leave them alone.
Yours are not so will need investigating a bit further.
If your not replacing seals push pistons out a small way and clean the dirt off the piston and grease before pushing fully in to accept the new thicker pads. Leave old pads in so you don't pop pistons out too far, then remove pads and clean.
WhiteSpirit is a good cleaner and tooth brush.
Ideally they should be serviced every couple of years, but before you ask I do mine when I change pads but only check and grease. If any binding on pistons I replace seals. Your pistons should retract when on bike and master cylinder cover removed with firm pressure by hand and slide in smoothly, remember your master might/will overflow and can ruin paint.
As said red rubber not for pistons, you can get enough of both ( Red & High temp) for several services in the little packets of Worth for a few quid.
If you do go for new seals go with a well known company who have good quality control.
As for choice of rear pads I don't use back brake, but that's another story that can go on and on.
First rule is be safe and stop safe every thing else is for fun.
