@sepulchrave That was my first thought also. Im gonna look a little bit more into it and then its either 288 brakes or bigger mastercylinder. Happy easter to you to

@carlston Thanks for your reply and time looking into it. I am aware that the fabia mk1 uses the same mastercylinder for the 256 and 288 brake discs. Thats what i have wrote above, that from my research the size doesnt seem to be the problem, but the mastercylinder. (Thats why newer models also have 256mm discs, because they have a diffrent master cylinder and brake booster) I wrote with some Fabia MK1 1.9 tdi rs owners with 288 discs as standard and they complained about the same problems that i described, for that reason some of them changed to diffrent mastercylinders and apparently it made a night and day diffrence (according to them) in terms of break pedal feel and fast "gripping" better/real pressure points instead of a "pressure windows". Included is a picture of a guy who offered master cylinder upgrades with these parts. 23,8 mm master cylinder, plate and tappet with small nuts in order to fit. According to many comments it made a big diffrence.

Thanks for the reply, the link throws me to google hompage (maybe because im sitting in Germany). I was wondering specifally if the above described sympthoms in my orginal post are completley gone after a new brake and disc upgrade, from my research till now, that doesnt seem the case. Maybe somebody has more knowledge or expierence. Since my fabia is also an underpowered slow car with drum brakes in the rear, i was wondering if people already did this if there were any complications.

Since my reply i already looked into etka, they are diffrent. Fabia mk1 is basically on of the small amount of cars that got the "bad" master cyclinder. The Fabia MC are 20,6mm diamater, Golf 4 audi etc. are 22 mm atleast most of them even 23,8 mm. From my short research seems to make the diffrence in break feel, respone. Only bad thing is that they arent easily interchangable, since the Brake Booster is also diffrent on the fabia compared to the others. At the moment im looking into this, if i got a solution and tested it out im gonna do a post about it. Or maybe somebody already did that upgrade to his fabia and can tell us

Thanks for the info/experience. Do you know by chance if your "tool eater" fabia only has bigger brakes, or also a diffrent brake booster and master cylinder. Since i was looking into this as well. Some people upgrade their master cyclinder and saw significant improvment.

Good to know that they came like this out of the factory. I mean the car drives and it brakes, it just feels unsafe and unstable. So was wondering if only 288mm upgrade helped.

Hello, I haven't found a suitable thread on this topic yet and think it's appropriate here. It's about the brakes on a Fabia 6y2 1.4 16v 75 hp (discs front, drums rear). Previously, I had an A3 8P with 288mm front brake discs (and discs rear) and generally good braking performance. Compared to that, the Fabia just feels very poor and, in my opinion, unsafe (late, sluggish, weak braking behavior). Is there anyone here who has converted their Fabia to 288 mm brakes at the front and can report whether it's worth it/makes sense and how the braking behavior is afterwards? I am simply very dissatisfied with the OEM brakes in the Fabia; it just doesn't feel safe. Since the brake discs and pads are uneven, the wheel hub probably has a lateral run-out, and I need new winter tires anyway, I thought about maybe upgrading the brakes directly. Does anyone have experience with this? Are there any problems with the strut, steering, handling, etc.? Approval? (Of course, the prerequisite is the correct steering knuckle, brake system, e.g., 1.9 TDI RS/mk2 Fabia from 105 hp, and 15-inch rims) Thank you very much in advance.
