I did it on axle stands on my drive, bugger of a job but you find a way to get enough leverage on them eventually.  Plenty of Plusgas also required. 

Is there enough clearance to get an impact gun in?

Not a chance for an impact gun.

Bugger.

Get the correct spline bit, you’ll round them off with a torx bit for sure.  Even with the spline bit you have to tap it in firmly to get proper purchase due to corrosion.  The carrier bolts should be replaced too, part number N90948802.  On the VRS you have to remove the carrier to change the discs, it’s not even a close call to get the discs off with them still on.

Have never replaced the carrier bolts with new ones, just cleaned the threads up put some some new thread lock on and done them up to the right torque setting, never had them self undo.

They’re stretch bolts and recommended to be replaced, whether you do or not is up to yourself.  I chose to replace them and faced with the amount of corrosion in the female spline section of the bolts, it was the way to go for me.  I’ve no doubt re used bolts will do the job but they’re inexpensive to replace.

A set of 4 bolts cost £16 from TPS, just ordered some. 

We did my fronts a few weeks back but no chance on the rears - its booked in at a garage for that.

 

My old A4 had a chamfer on the rear carrier allowing the disc to come off without having to remove the carrier ... not so on my Scout!

Yes mate the fronts are so easy, did them a year ago. Rears on the other hand, a pain in the ar--. The cars is booked in the garage this Friday, so I guess I have to pay them to do an easy job, just because Skoda fit hard to get at and bloody tight carrier bolts. 

Mines due a fluid change so they are doing that at the same time

Never needed to in my experience but YMMV.

On the bigger diameter rotors the carrier can stay on.  On the smaller diameter rotors the carrier has to come off.

 

To the OP.  

Did my carriers on floor stands last year.  I think I used a weird combination of 1/2" drive triple square with a 1/2"- 3/8" adaptor to get some clearance and 3/8" bar.   I pushed the whole lot with my foot as the leg muscles can give a greater sustained force.  Belting with a hammer wasn't going to touch it because the suspension movement was absorbing the force.

Just an update. 

 

Did this yesterday and yes the caliper bolts are bloody tight. There is enough room to get an impact gun on the bottom but because an extension is needed it robs all the torque and doesn't budge. 

 

I ended up getting the bottom one with a long breaker from underneath and the top one was inaccessible so I took out the rear shocks to get at them with a breaker. Taking the shock out is easy as I've done it before for the end stops. 

 

No chance of jacking under a ratchet as it moves with the suspension unit so unless the axle stands are on the control arm this won't work. 

 

Reused the old bolts and put some copper slip on them although I can't see the brakes being done again for the life of the car. I can't see them backing off as they have a locking washer on them anyway. 

 

The discs were rusted on fairly tight so took some bashing with a mallet to shift them. Good idea to clean the mating face up on the hubs and copper slip it. 

 

Also repainted the stone guards whilst the discs were off as they were looking worse for wear. 

 

Not too bad of a job for anyone thinking of doing it, just got to be patient and think outside the box a bit. 

Well, got the new disks and pads on the car today, it was really easy in the end. 

 

Had them done by my local independent garage for an hours labour charge, £53.  Bloody carrier bolts!!

That's not bad labour wise. Get to stay in the warm and hands clean.

You are right on both counts. I have been using this garage for years and they certainly charge a reasonable rate. Far better than me getting under the car again trying to undue those bolts. The garage is only a 5 min walk away as well.
