I've enquired about a pair from Rolling Components at £102. It says they're for the vented discs though but l wouldn't have thought it would make a difference whether you have vented or solid discs, which l do. The photos of the actual calipers do show a much smoother casting & l don't mind spending a little more on a pair.
Solid discs are often thinner, as they don’t have to make room for the air gap. This can result in different piston travel measurements.

Yes, they are thinner by about 5mm l think. But are the pistons in the vented disc calipers any shorter than the solid disc ones? If not it shouldn't make any difference to the piston how thick the discs
are, surely? It'll just come out as far as it needs to in the same way as it does to compensate for pad wear.

I just paid Mickyboy £25 each for all four callipers. They need cleaning and refurbing, but I'm happy with that price

Yes, that's cheap. l could refurb mine l suppose but l was looking to do a quick swap job outside the house. I could just get cheap ones & refurb my originals at leisure.

My enquiry was answered. The vented disc calipers have a larger piston than the solid disc items.

I've ordered the correct calipers from the ebay suppliers of the vented disc calipers:

https://www.jasauto.co.uk/

They are originally supplied by Rolling Components of Basildon, which l quite liked the sound of when l looked them up:

https://www.rollingcomponents.com/

You have to be registered to order direct from Rollco but you have to be trade too. They're refurbished as far as l can see but as l said, they do look much better quality than the bulk of the 'bay 'brand new' offerings.
Anyway £138 all in for the calipers & 'best quality' pads. We shall see when they arrive.

I looked at the defunct caliper at the weekend & pushed the piston back in but to be honest it all looked pretty rough & the pads didn't look as if they had been in proper contact with the disc for some time, the surfaces being very uneven & the bottom edges crumbled away in places, despite not being fitted that long ago. Most unedifying. Component quality has become so hit & miss that you yearn for the old days of reliable motor factors in every town.

I fitted them today, quite straightforward all told. I clamped the hoses to remove them (l know some advise against this), let gravity do it's work once the new ones were on then the good lady gave the pedal a couple of pumps & presses to expel the few air bubbles there were.
I suspect the rough surfaces & crumbling edges of the pads in the sticking caliper was heat damage.
I cleaned the discs up with sandpaper & did the same with the handbrake drums & shoes.
