Hi all,

I've been researching upgrading my 280 brakes to 312 brakes. I'm aware it's loads more work than upgrading the 288 brakes but oh well I want/need better brakes.

 

Aware the FN 3 calipers for the 288/312 discs are used in numerous cars but there appears to to be two piston sizes 55 and 57. 

 

Which one is correct!

 

Thanks.

Changing from 280/288 to 312 brakes means that you will no longer have the option of running 15" wheels. 195/65R15 tyres are a good size to have if you need winter tyres and it's a cheap size.

 

Maybe consider fitting new discs and pads if your brakes aren't working well?

Hi. Thanks for the suggestion. I tow a few things, including a caravan to the Alps etc (although probably not this year by the look of things) so wanting to upgrade. My fault in getting a 110, thought the brakes would be as easy as the engine to upgrade to the higher spec car!

 

Should of just got the calipers from a scraped yeti but some came up cheapish so I picked them up and then I saw the piston sizes issue. I'll resolve it eventually.

I didn't think you could fit 15" wheels to a Yeti anyway?

Yeti's were never equipped with 15" wheels, and are not Type Approved for them.

In the UK, motorists are allowed to fit non-Type Approved rims and tyres. As long as you inform your insurance company of any modifications.

Would you let one of your family drive a car with a non-type approved rim and tyre and accept the consequences if anything went wrong?

Many of us are safely driving around on tyre sizes that weren't approved by the factory. It's simply not possible or economical for the factory to approve all possible tyre sizes that are currently available. Not only that, but new tyre sizes are often introduced. Even the car manufacturers themselves, will sometimes offer new tyre sizes.

 

Take the Fiat 500 for example. It was available with three different tyre sizes. 175/65R14, 185/55R15, 195/45R16. Gradually over time, Fiat pulled the higher profile tyres in certain markets, so that one market in particular, ended up with just 195/45R16. This wasn't because the narrower, higher profile tyres were dangerous, it was because of fashion. Wider, lower profile tyres meant more sales. People loved the look of the car in the showrooms. It wasn't as good out on the road because people started to realised that these wider, lower profile tyres weren't so comfortable...but that's a different story.

I suggest you read the Type Approval documentation for the Yeti, together with the Construction & Use Regulations and have a discussion with the DVSA Inspectorate before you make incorrect comments like that. It is perfectly possible for a manufacturer to Type Approved all possible variations on a model if they so desire, and they do.

Whilst you might get away with it I can assure you that a Vehicle Inspector from DVSA or the Police could confiscate any vehicle that does not apply to any of those Regulations if he felt so inclined. What Fiat fit has no relationship with what Skoda have Type Approved for the Yeti.

Your advice is incorrect and should be ignored.

DVSA inspectors do not have the power of seizure, Police yes for certain moving violations, no insurance etc, highly unlikely for non type approved tyre sizes except in dream world, and thats assuming that they would even have the knowledge.

 

Back on topic. to the OP, I too wanted to upgrade my brakes and thought it was a simple change of caliper carriers using the existing calipers to use the 320mm Golf GTi set up, unfortunately the car was in another country when I bought a complete set of S/H calipers, carriers and discs on E-bay, I only really wanted the caliper carrier brackets, my calipers would be newer and better and I would have bought new discs.

 

When I got the car and the parts together I found that my calipers bolt straight to the suspension strut, there are no carrier brackets, I guess it means I have the 280 discs that you speak of, mine is a 108hp vehicle, could you tell me what it is I need to buy to go for bigger brakes and what vehicles they were fitted to as standard, like you I will be towing and also having a stage 2 remap, the brakes are currently very poor due to corrosion where the vehicle was stood so long in the salvage yard, good enough to pass the MOT but still rubbish so I am keen to do the upgrade sooner rather than later.

Hi. I'm leaving the wheel size issue alone (I have 17 and may put 16 on for winter if some come up cheap). 

 

If you have the 108 model you have 280 disks ( but best to check!). These are fs111 calipers and this is written on the side so you can easily see. 

 

These have no carrier as they bolt to the hub knuckle. To mount the fn3 brakes you'll need a new hub knuckle which takes a caliper carrier. These were used in numerous vag cars but I've gone golf Mk5 as that's what a scrappy had available in good nick. Be aware, like the yeti, lower spec cars also had the fs111 calipers and hubs so aren't suitable. The new hub knuckle takes a 55mm suspension strut, the old one 50mm so not compatible - you can either put new (or upgraded) dampers on or a shim.  

 

The fn3 brakes are used on 288 and 312 disc sizes, they are the same as far as I understand apart from the calliper carrier so you can decide what size disk you want. 

 

I've yet to do this so I may have missed something off, but will update. 

 

The easiest way is to strip the front off the correct yeti!

The schematic diagrams on the oemepc.com website show all three front disc sizes. 280x22mm, 288x25mm, 312x25mm. As has already been pointed out, it appears that the 288mm disc is much easier to convert to 312mm than the 280mm.

 

Interestingly, the schematic diagram shows that the 288x25mm front disc is suitable for 15" wheel rims. Here's the title to that schematic diagram. Maybe Skoda were planning to release the Yeti with a 15" wheel option early on in their plans but changed their minds. 205/70R15 is a good size for All-Terrain tyres and messing about in the mud, so it's sad to see that Skoda limited themselves to 16" and 17" options. Maybe the marketing people said no to the 15" option...such is the relentless pursuit of ever wider and lower profile tyres.

So if I have understood you then the brakes that I bought (which are once again in another country 🙁), the calipers, carriers and discs can be used if I buy and fit some hub knuckles for 55mm suspension struts?

 

I know that I will have to rebuild the calipers in that case as they are very knarly.

 

Are they described as "hub knuckles" by the breakers & Ebay sellers?

 

Should I search for VAG hub knuckle FN3 caliper?

Probably best to search for the OEM part number - maybe even tick the box on ebay that also searches the description as well as the title. That at least quickly limits the search results to manageable proportions, rather than using just a description. You might need to find all OEM part numbers though in order to do a thorough search on ebay. Google "Skoda parts catalogue" to find websites with Skoda online parts catalogues, such as "oemepc.com" and "skoda.7zap.com". You might even find that you can play one seller off against another on price, especially if it's a slow moving part and multiple sellers are trying to shift the same part. I recently did this, and fixed my car for £15 rather than the new price of over £90 for one part that I needed.

Am I correct in assuming that I cannot use my (presumed) existing FS111 calipers together with the other hub knuckle and caliper carrier and larger brakes?

As far as I'm aware you need the fn3 calipers. I've not checked to see if the others physically fit but the more powerful cars use the fn3 so there must be a difference.
