Hi. I have a Skoda Octavia 1.0 TSI 2017 and I want to change my front brake discs. Every site recommends multiple sizes, which size should I go for? Thanks

The same size that you have fitted to your vehicle, measure it because nobody on here can.

 You need the build codes for the car.  They're either on a sticker somewhere or there's eBay sellers who supply them from the vin.

 

 

You can then look up the disk sizes in this thread.

 

Or use your eyes and a tapemeasure, use a bent coathanger or similar to make a caliper gauge to avoid removing the wheel.

 

On a scale of 1 to 10 your own eyes are 10, what some random person on the internet reckons a 2 or 3, VAG build codes should be 8 or 9 but the sticker only lists one axle (cant recall if its front or rear) and Eurocarparts minus 10!

 

Unless there is only a choice of 2 then  you can confidently choose the other one from what ECP say will fit your car.

Jurid on autodoc lists the Octavia MK3 1.0TSI 115HP as having 288x25mm front brake discs.

 

You can confirm this if your car has build code 1ZE.

 

1ZE is a TRW brake system, ie. the front brake calipers are made by TRW.

 

Another way to check is to look at the brake calipers and see which they are from the photos below.

There are various sites which offer a VIN DECODE service, some of which used to be free, many now expect you to pay a fee now. (Nothing massive, but it's a bit cheeky, IMO.)

You only need to do this once, and once you have the information, you have it forever. (I used this website https://carinfo.kiev.ua/, and when I just checked, they still have my VIN decode details on there, but I don't remember the site being in Russian!!)

 

The VIN decode is about 7 pages of 3-digit codes, and the explanation of each code. It tells you all the part options and configurations for your vehicle.

 

So in my instance, for brakes, I see:

1KS     Brake type in rear: Disc brakes in rear (Geomet D)

1ZA     Brake type, front: Disc brakes in front

 

I can then go the the thread that @HappySam helpfully linked to "Skoda Octavia MK3 5E brake pad sizes", and see the following choices for my VIN decode codes, as provided by @Carlston in that thread:

1KW 310x22mm ATE 24012202191

 

For front disks for my car, I could choose brand TRW, 1KS 272x10mm TRW GDB2042 or brand ATE 1KS 272x10mm ATE 24011003561.

For rear disks for my, I could choose brand TRW, 1ZA 312x25mm TRW GDB1956, or brand 1ZA 312x25mm ATE 24012501581.

 

I can then go to a parts supplier like AUTODOC, https://www.autodoc.co.uk/ enter the part number, example 24011003561, and get details of the part and the cost of parts associated with that parts number.

Hope that makes it all fairly clear and straightforward.
