Hi guys

My Octavia 2 FL makes rattling noise on rough asphalt, exposed stones, small cracks. Brakes, system ATE, disc 280mm, pads Febi 16328. When I press brake pedal quiet. When release rattling comes back. I even replaced one rubber sleeve. New Febi sleeve is more loose than orginal ATE Skoda OEM sleeve. I replaced guide pins for brand new ATE. MOT in March nothing in suspension. I know sway bar link clattering noise. I think left side is louder than right or it is noise from left wheel. Any ideas guys?

fight with brakes: day 46

any ideas welcomed guys

rattling noise

inner pad should be that lose?

It maybe the aftermarket febi pads are slightly smaller/larger than original or the carrier is worn. Had similar on mine. Cant remember the make of pads but I had never heard of them. I measured each one and there was a slight difference of about 1mm between the four. I replaced with Apec and they seemed tighter in carrier. Could also be the spring that holds pad into piston that needs opening up slightly.

I will try Brembo and Textar pads. I dont believe in "lose rubber sleeve" theory. Tomorrow is day of the days. I start fight at 8oo. I need some results. Im going to Germany soon.

I wonder why I dont have cable for worn brake pad sensor alarm 🙄 Pads comes with cable and socket.

Scary movie part 3. Chat gpt told me that peoples solution for rattling is to swap knuckle for 288 disc, removable caliper carrier and caliper with spring

here is similar problem

Not sure why there is no wear sensor cable. There may be two options. Try LLLparts original manufacturer diagram using vin and see if you can get the OEM number from diagrams. You may need brake PR code from sticker normally in boot.

You probably know this @kokosal , but the inner and outer pads are different, and can rattle if an outer pad is fitted in the inner/piston side. The retaining clips are different.

I've marked on your image (you don't say which pad was from where) which are inners and which are outers.

Check that you have correct outer pads on both sides, that should guarantee that there isn't a positioning mistake.

Here's an image of mine showing the difference in clips:

Guys dont look at piston shiny marks. I have put pads in any configuration during experiments, proper, wrong, left wheel, right wheel. I know that kolbenseite should go to the piston.

I need dismantle it again and understand what was the poet trying to say while designing that inner spring. I assume he wasnt an idiot. When we expand it with pliers and then slide back into the piston we ruin the holding force.
