defender brake caliper ???????

hi guys
its been a qhile shows all was going okay in the landy world
so i have a 84 defender
but i believe a discovery axle
so it may be discovery brakes attached
thats my problem had the wheel of today to look at replace/repair as the MOT spotted pads very worn down and pistons possibly rusted
so i want to know what caliper i have and what brake pads fit and what piston repair kit i need just to keep my options open on what i can do but fiding the correct caliper will be a start
any way only marks i could find were on the caliper and it looks like seriel number LB10TY016AC brand is Lockheed and its the front right caliper

many thanks

several pics would be more help

pic as sugested

Not a standard 84 set up anyway

Look like 110 callipers

looks like 110 calipers since vented stc1266 and stc1267 which seb500460 and seb500470 are a later superceded number ie you could use either

is there caliper repair kit for them
