Quick one, at what point do you say it's not worth
continueing trying to refurb rusty calipers? Pistons are
stuck aswell

About half hour with a wire brush so far

Blimey they are rusty, I would get a second hand set for £60 and refurb them or maybe get these?

Providing theres still plenty material maybe ship them off to godspeed etc see if theyre good enough to rebuild

Forget the wire brush and get some hydrochloric acid , soak them in that to remove the rust , you will be there forever with wire brush mate

Looks like they have been rough carved out of a lump of coal.

Where would I get hydrochloric acid?

Ah, I see it's used for patio cleaning so I guess
B&Q would do it.

Find a polishing shop near you or get them shot/bead blasted that will clear them up nicely.

Also, how come the inner part of the caliper is rustier than
the outside part?

Personally I wouldn't waste money trying to refurb those, you would be better off either buying a better second hand set and doing those, or buy a set already done from one of the traders on here.
You might even get a few quid for yours doing a service exchange.

That's probably the route I will go. These ones were on a 2001 bug I bought
just before Xmas and had seized on passenger side within a month.

I replaced them with some decent used ones that came with drilled and
grooved discs so thought I would try my hand at refurbishing them but
I don't think it's possible with my limited tools.

Might save up and get some of the wrx pro jobbies.

I thought that was some type of fossil that's just been discovered.

Lol, yeah a fossil from 2001.

It's a WW2 relic!
I'd get shot of those, peace of mind with brakes etc.

I'd be straight on the phone to Godspeed.

You're a brave man for even attempting to refurb those...

I have admitted defeat on them for the moment.

Is it worth splitting them and saving the bits that are salvageable?

I would say nothing is salvageable on those. The pistons will most certainly all be pitted.
I stripped a much better set than those recently and discovered that only one of all 8 pistons was in good enough condition to re-use. So I decided to get a set of stainless steel pistons and seal kit from GodSpeed. Have stripped everything back as much as I can and this week I will drop them off at company local to me and they will shot blast and powder coat them, all for £25. (mates rates)

Once back I will fit the new seals and pistons and then re-fit to my car. In the mean time, I bought and fitted a set of wrx pro calipers which are bloody good for the money. I'm a bit picky though and want both calipers to have the white Subaru writing!

Honestly mate, sling them in the bin.

God speed are AWSOME, recently refurbed mine on a £235 exchange basis. Fantastic quality
