I have a 2019 Octavia and want to change the front discs and pads.

Question.....can you channge the discs without having to remove the caliper carrier which is held by 2 big bolts?

Correction 2017.

You might be better looking at and/or asking in the 'Skoda Octavia Mk3 (2013 - 2020)' forum, link at end of post.

I didn't have to when I done them on my wife's 2015 Fabia but the2017 Octavia might be different, I've put links to the notes and tips threads I put up for front and rear changes on my wife's car, I don't know if any of it would be any good to you but here they are.

Depends on the car. With some of the smaller discs (like on a Fabia) you should be able to wiggle it off, whilst anything larger you will have to remove the carrier.

I'd be inclined to suggest that if you aren't comfortable removing the two carrier bolts, you maybe get some help doing the discs? FYI IIRC the caliper bolts are the 200nm stretch bolts, so you'll need to replace them.

As a generalisation, that would depend on the brakes and that is more dependent on trim level and engine that model year.

Also, depending on brakes fitted you may need to remove one or both of those bolts to change the pads anyway.

This may seem unhelpful, but anyone who doesn't have access to your car will need this information.

The carrier bolts do not need to be removed to replace brake pads.

I've just had a look at the manual and there are two screws (self locking) which are torqued to 35 Nm, and it says "replace after each removal".

There are two screws (carrier to hub bolts) torqued to 200 Nm, and it says "clean when using again".

They're the stretch bolts then. Usually things are safe to reuse as long as it's not a 'fasten to 90nm plus 90°' situation.

That being said, bolts aren't expensive. I always prefer to replace the high-torque calliper bolts, but that's just me!

I don't like to disagree, but if Skoda are saying that they can be re-used, they aren't stretch or 'torque to yield' bolts.

Most bolts that people think are, aren't.

Angle tightening after a lower initial torque is simply a far more accurate way of tensioning fasteners than torque alone.

Friction makes up so much of the torque 'resistance' that it results in highly variable fastener tension.

Angle always results in same increase in tension, because the extension of the bolt is a fraction (e.g. 90/360) of the thread pitch.

Sorry - I was meaning that the 'replace after each removal' bolts are the stretch bolts!

Good to know @Breezy_Pete, you learn something new every day. I always thought the torque was XYZ, and then you do an extra X degrees to sort the clamping force/stretch. I never really though about a fastener being 100nm, or 70nm plus 45°.

Setting aside the friction of the threads it would be interesting to see strain gauge tests of bolts tightened to equal torque with plain washers under the heads against axial roller bearings. Then testing with dry threads and bolt/washer interface against lubricated.

No doubt there is something on Youtube
