Hello,

I can't understand something: does my SKODA ROOMSTER (5J) 1.6 TDI (66 kW / 90 HP) use front brake discs that are 256mm (FS III 256X22MM) or 288mm (288X25MM)? I don't know if I can use both sizes or just one, but I can't find which one is suitable for my Roomster model. Additionally, it seems that the 288mm disc is only available with a wear sensor, which I believe I don't have, is that correct? Can anyone help me understand?

Thank you.

If you have the FSIII system, I think the brake caliper will have FS - III stamped into the outer face quite visibly.  If you have the larger brakes I think you will have a different caliper with something else marked on it.

 

 

If you tell me the 17-character vehicle identification number I can look it up directly for you, also.

@Uorren As @Breezy_Pete illustrates, the callipers with the 256mm discs literally have the text "FS-III" cast into the outer faces. I think the callipers with the 288mm discs will have "DS-3" cast into them.

This was readily legible through the spokes on some wheel designs.

Or even easier, the 288mm callipers have a vertical wire "spring" running down the outer face.

 

The issue with pads for certain brakes only being available with wear sensors occurs right across some models and marques.

 

The solution is just to cut the wiring off as close to the top of the pad as possible, I tried desperately to find the correct front pads for my wife's 2015 VW Polo that does not have brake wear system included - then properly read the comments in an online parts car, what was written was basically use the ones with a brake wear sensor built in (as there are not any supplied by VW Group that don't have a wear sensor) and cut off the sensor.

 

Edit:- I've never noticed any useful identification on at least the later version of these 288mm callipers, even having owned a car from new with them, the version on some 2015 cars is FN3 in the case of my wife's Polo, FN3 - 54, ie 54mm pistons.

For your Skoda Roomster (5J) 1.6 TDI (66 kW / 90 HP), the correct front brake disc size typically depends on the specific configuration of your vehicle. The 256mm discs (FS III 256X22MM) are often used in the base or standard models, while the 288mm discs (288X25MM) are usually found on models with higher trim levels or specific packages. You should check your vehicle’s specifications or consult the owner's manual to confirm the exact size required. Additionally, the wear sensor is usually associated with the 288mm discs; if your current setup doesn’t have a wear sensor, it’s likely that you have the 256mm discs. To ensure compatibility, it's best to consult with a dealer or a trusted mechanic who can verify the correct brake disc size and confirm whether your vehicle is equipped with a wear sensor.
