Size of disc and caliper is irrelevant,

If one is not working efficiently 90% of the time its down to trapped air.

I'd only do the caliper that isn't working.

Using the 2 man method get someone to pump the pedal a few times then hold the pressure on the pedal whilst releasing the bleed nipple. When the pedal sinks to the floor, lock off the bleed nipple and then your assistant can let the pedal rise. Repeat this process about 3 times.

Do each nipple on on the caliper like this seperatly.

Appologies if you know all that - but it will be useful for others.

Its amazing how much air you can get out using the two man method over an eezee bleed kit, also, if you are having problems with a soft/long pedal etc, try bleeding the brakes from the unions above the calliper, exactly the same method as the nipples but makes abit more of a mess, but also gets rid of a lot of air

one trick i found out was that if you hook everything up and just leave one the bleed nipples open, gravity does a lot of the work for you

you obviously have to bleed the brakes properly but you would be amazed at how quickly the air comes out

My ABS is also totally standard. As has been said, it will be an airlock in the calliper that isn't working up to full efficiency .
