Picked up my 3rd Vrs last weekend and overall I’m really happy with it, this is my first mk3 fwiw. 
 

When we picked the car up I heard a rattle which I put down to a front drop link and as I will be lowering the car I wasn’t fussed as I’ll change the links at the same time as the springs. I’ve had a lie under the car today and the links seem fine. 

 

The rattle happens when going over rough ground or potholes but not softer bumps or speed bumps. There is also a knock when stopping in reverse as if the pads are moving upwards in the carrier. All pads and discs are new, pads are cheap eicher ones from euro by the looks of it. 
 

Is this an issue anyone has heard of before? 

 I’ve had the knock in reverse before but not the rattle over bumps. I’ll try and attach a video and pic of the pad in the carrier. 
 

 

Loose brake dust cover? 

It sounds heavier than a dust cover in person tbh. I’m heading back up close to where I bought it so I’ll take it back in and let him hear it tomorrow. 

I have all new Bembo Xtra pads and get the same knock from the front brakes when they "sit" in the braking direction. No rattle however.

Most pads have the anti rattle spring clip on the tips of the pads. They just need taking out and spring clips spreading out slighlty.

The 340mm front brakes on the Octavia MK3 RS is a TRW brake system.

Went and spoke to the seller today and the car has to go in next weekend (earliest I could do) and they’ll look it over. I was toying with chucking a set of pads in it but I shouldn’t have to. 
 

thanks for the replies. 

You will need oem or TRW pads for some reason they are really fussy.

 

 

They can clunk even with genuine pads. The caliper guide is slightly larger than the pads to prevent the pads expanding and becoming stuck when really hot. Most performance brakes do this but they have a large spring clip to keep the pad in place. The TRW calipers do not for whatever reason and causes the pad to move and clunk slightly.

I had Brembo pads put onto my Superb 280 and they clunk over rough surfaces but don't clunk over the same surface if I apply the brakes slightly. I can even move the pad with ease using just my finger. Car been into my mechanic 3 times since having them fitted and now he is going to change the pads. I told him I wanted TRW as the OEM ones are nearly 3 times the cost but I don't think he likes my opinion!

Hello all, I would like to repost on this thread my findings on this horrible noise. I was almost subject to a large mechanics bill myself before trying this out. 

 

I've had MK3.5 Octavia VRS for around a month now and have had this noise for almost my whole time owning the car. What started with mine was brake squeal, which prompted me to have the calipers off and pads out. There was no copper grease around the edge of the pads, after fitting some grease and refitting the squeak was gone but  I had this horrible clonk when going over rough road, pot holes but not over speed bumps. 

 

I had a mobile mechanics come out and take a look, all of the other suspension components, lower arms, anti roll bar bushes, drop links, struts and top mounts were fine. The mechanic told me my driveshafts were knackered and there was play up and down in them as well as an oil leak from the gearbox I had a look myself and found he was telling a lie. He took my money and ran because he didn't know what the issue was. Minea a 6 speed manual. 

 

It was that evening that I was speaking with a friend who said if it isn't the above it could well be brake pads. So I went outside with a screw driver and lightly pried the pad up in the carrier DONK, pried it down DONK. There's your issue. There was around 5-6mm movement of each pad in the carrier.  

 

Headed down to euro car parts the next day and bought a set of pagid pads. (175mm) Fitted them in myself and they are a snug fit. No movement up and down or back and forth. One happy man. The pads I removed were brembo. They didn't have any of the plates fitted to the rear of the pad, the pagid do and this stops the slack on the pad thus solving this issue. Very simple fix to a very annoying problem. I hope this helps you all. Don't buy brembo pads buy OEM (TRW) or Pagid.  Have a good weekend 😁
