Can anyone advise on the compatibility, or otherwise, of shimano deore lx 2007 with current deore/slx kit?

Specifically, i have the LX M585 disc brakes but one of the calipers is playing up (stuck piston – have tried cleaning/bleeding and no change). Could i swop it for a current deore/slx caliper (m585 calipers appear to be difficult to come by).

Any advice gratefully received.

I’d be interested to know that too as my M585s don’t work well in the cold (dodgy seals apparently) and may need replacing before next winter. I’m pretty sure they’re compatible but confirmation would be nice.

Think i’ve found the answer to my own query:

Essentially, with the exception of the SLX (i think, M665?), all BL and BR models are interchangeable.
Sorted.

I emailed the UK Shimano Service Centre about my issues in cold whether and they stated that BRM595Fr or BRM595FRW are the equivalent callipers (to the M585s I assume) and would be compatible witht the levers.

assuming you have the right connectors any shimano hydraulic disc lever is compatable with any shimano hydraulic disc caliper.

currently running old saint calipers with slx levers

IIRC only the original XT (M755) and the new XTR aren’t compatible, everything else will work with everything else.
BTW I have an XTR front with a M595 lever and its fine.
The M595 calipers are a straight fitting.

Great, thanks for help with that.
