Both the carrier and slide of caliper part. Do you know the torque settings?

 

2008 Octavia 1.6 petrol.

Carrier bolts are 90nm + 90 degrees, note they are stretch bolts so you should really get new ones each time they are removed.

 

Caliper pin bolts are 35nm

Thanks.

 

My next problem is there's no room for the breaker bar in there(carrier bolts), the shock is in the way, there is a bit of room to put the bar from directly underneath but that would require some Jacking up or a lift, any tips?

I'm going to follow your procedure here.

 

 

When you unbolt both the spring holder and shock strut, will you be able to turn the hub assemble toward you so that the hub will be at at angle of 45 degrees or so or would this require unbolting more joints attached to the hub?

No need to remove shocks, just use a 18" Halfords breaker bar and you will be fine

How can you know if air has got into abs system?

You will probably have a spongy brake pedal but you don't need to touch any of the brake hoses to replace your brake discs

The dust boot slipped out from the piston bore, I don't remember if it was slipped when I started or beforehand, as a result there's been a lot of fluid leakage. I've ordered a new caliper and it should be straightforward installing it but I'm worried there may now be air in the abs system?

unless you have completely drained your brake reservoir dry I can't see air going getting into abs system, so just will need a normal bleed for when you replace your caliper.

 

by the way did you manage to find out your exact rear brake disc size as some lower engine models have smaller discs than 260mm discs and you can get away without removing the carrier bolts to change the brake discs

I measured it as 256mm but I was using a metal ruler and it's difficult to get it to the mm, I could have been a couple of mm out etc, eurocarparts were right it seems however I haven't tried to fit it yet. Skoda dealer did look up my details and said 260mm also a data sheet someone on this forum linked me said 260mm.

 

So the fluid was leaking from this open piston bore for quite a long time would that not result is drying out the brake reservoir?

If you brake reservoir is now completely empty then  yes, air would of probably got into the abs system, but if it was a slow leak and you still got fluid in the reservoir then you might be fine.

 

But good news is that if you have smaller rear discs then you don't need to faff around with the carrier bolts as they can be a pain to remove.

This worries me as the current discs won't remove without removing the carrier so maybe they are 260mm after all, I'm still working on removing the carrier.

 

If my brake reservoir is dry can I top it up, bleed the system and drive it even if air has got into the abs system?

 

I may need to drive it to garage etc?

I just bought this 38mm bore caliper from eBay which the description says should fit my car, 2008 Octavia FSI 1.6 etc. 

 

Now I measure the caliper I've just removed and it's 41mm piston bore. I assume I'm measuring it correctly?

 

Have I ordered the wrong caliper?

Visually they are very different calipers - one has a ribbed top, the other smooth and rounded. A quick eBay search will reveal that you can buy a new one for nothing more than the cost of a rebuild kit. That will also tell you which size it is. Buy another one of those. For the correct side since they are handed.

 

I'd agree on the rigid lines as well. Try some local motor factors instead of a garage as they may well be able to make them up for the cost of a couple of ends and five minutes of time. 

Reviving old topic,

 

I'm going to attempt to remove these caliper bolts, part of replacing caliper, pads and discs. Bought an adjustable breaker bar,a shorter m14 bit and m12 bit incase..

 

I'm a little stumped, as I see it's a M14 spline bolt.. ok, which it was when I looked.at it today  . But I look for a replacement stretch spline caliper bolt and I only see M12... Is it wrong or am I misunderstanding m14 bit fitting into m12?

 

For example here it's m12
