The brakes don't seem to be getting noticeably hot. It was hovering around freezing on the journey to work and after the 16 mile trip to work there was not obvious heat coming from them

The  brakes would only be over heating if the caliper was seized on, not allowing the pads to release properly after braking. Though that's not to say it's not partially seized? There is only one large piston per caliper so either the piston isn't being forced out squarely or the caliper isn't floating backwards and forwards as it should?

 

Though as someone has previously mentioned something could be damaged? Or maybe the dealers fitted 2nd hand disks and the pads haven't yet bedded to the worn faces? As clearly there isn't full brake pad contact on the disk ( Rotor as the Yanks call them) face as the rust is forming and not being cleaned away.

  

 

I take it you don't do your own repairs? If not as someone else has said take the car to a small independent garage and ask them to look at it for you.

I repeat, look at the old disk photos and the new disk photo shows EXACTLY the same pattern. No contact on the outer 40% or so.

 

I presume this only aafects one side, the OP has shown both old discs of which only one has that rust band but only shown the one disc on the new set.

 

 

Old disc

 

New disc

Something is bent, broken or incorrectly fitted.

 

A good independent should sus whats going on after a few minutes looking.

But the Op hasn't actually stated if it's the same disk on the same side? maybe the disk has been swapped to the other side ???

The first picture in the original post is the same side of the most recent phot uploaded yesterday. Both front discs and pads were replaced in January

As Xman has said there is something not right ! It can't be a coincidence that two discs on the same corner have rusted in such a way in such a short period of time. The rust isn't the issue here. It's what letting the rust occur that's the problem. Something is damaged or mounted incorrectly?

Edited 2 March, 20224 yr by Derbyshirebod

If you were to check the inner face of the disc, I suspect you will see the outside area is shiny and the inner area rusty, i.e. an inverted pattern that would confirm the caliper is not aligned square to the disc.

Bent slider pins maybe ? Or the caliper carrier is not mounted flat  ?

Does any one know if there is more than 1 disc size on the front and rear?

From what I can see.

 

Skoda Superb 1.8 4x4 - 2.0 4x4 Tdi (2008-2015)

Front vented brake disks Ø 312mm

Rear solid brake disks Ø 282mm

 

What makes you ask that?

It depends on the build codes.

 

For the Superb MK2, the build codes for the brakes are as follows:

 

1ZE

288mm front discs

 

1LJ or 1ZA

312mm front discs

 

1LA

340mm front discs

 

1LK

345mm front discs

 

1KF

260mm rear discs

 

1KS

272mm rear discs

 

1kJ

286mm rear discs

 

2EA

310mm rear discs

Bulid code. Is that the sticker in the boot?

Some of the build codes are on the white sticker/label in the boot. Most are not.

 

There might be around 180 build codes that are associated with your car's VIN number.

 

Skoda would have known what all your car's build codes were going to be, even before it went down the production line to be assembled.

 

However, now you know all the possible variations...it should be a simple job to measure the outside diameters of the brake discs to find out what you have.

 

Possible front brake disc diameters for the Superb MK2

288mm, 312mm, 340mm, 345mm

 

Possible rear brake disc diameters for the Superb MK2

260mm, 272mm 286mm, 310mm

 

It's unlikely you will have the 340mm or 345mm diameter front brake discs, or the 310mm diameter rear brake discs...unless you have one of the most powerful cars.

Spoiler

 

Ive got that sticker in the spare wheel well but i cant find the code for the discs. Unless im going mad !

A 170 bhp is more than likely going to have 312 mm front and 286 mm rear disks. If I remember rightly, brake codes are one of the ones they don't put on the build label. If you go to https://erwin.skoda-auto.cz/erwin/showHome.do

and download the Vehicle Specific Information document for your VIN it will have the full list of PR codes for your car. An hour's sub would be enough for that. You can also download service manuals there.

1KJ for 286mm rears is there in the first row. Front brake PR codes likely not to be there, so much so that I won't bother double-checking.

Thanks for the helpful advice here and I have just bought a pair of Bembo discs and pads for my 4x4 Superb.

One question,thinning discs and pads was picked up as a caution on my MOT. Are there wear warnings on the Superb or does it mean that mine are not working?

There's a pad wear indicator but it's not triggered until the pads are very worn.

Thanks. Mine are quite worn but it isn't triggered as yet. I'll hang on for a little longer as not making any noise at the moment .

The wear indicator is only on the passenger side front inner pad.

so it is possible to get the pads down to metal on drivers side beforehand.

Another indication is if your fluid gets low ( warning light will come on) because the pads are badly.

Kept telling a lad years ago to stop topping fluid up on service because when the pistons are pushed back it used to just flood out
