Pagid RS4-2s pad build up / vibration

I had this with S3 rotors and DS2500 pads. It was pad pick-up.
Not great pads on a trackday.

I have different brakes now but I'm using Pagid RST3's which have had no issues at all.

I thought warped discs was an Internet myth.

Interesting thread as Iv not long gone the TTRS caliper route,albeit with the 340 j hooked discs but running a cheap pagid pad for daily use.

You got any track footage?

This is pad deposit not disc warping.

W4nk pads

Usually discs being too hot and warp causing vibration as I had this on mk1 tt and had to replace discs and pads. It was mapped stage 1 with LCR Brembo's.

To warp a disc you have done well. It's 99% more likely to have her pad deposit. Unless you checked them for run out?

I did check the discs at work for run out and confirmed they were buggered.

In that case well done. Not the case here tho.

Some dodgy geezer sold me these pads..... Never agsin

Skim / grind your rotors to fix it Rich? Or just give em a battering with different pads/ rs29

Makes me sick what the blues cost when I think of be vibrations when I press the slow pedal

Shame that... dodgy fecklers out there

I didn't get the dti on them but am sure it was deposits from the blues.

blues?. pads.

Your running some expensive set up so maybe the pads are fouling the discs and causing vibration but personally I've not heard of this before. Happened to my brothers Carrera 4s so we bought oem parts and once discs and pads were replaced bedding in time was given to around 500 miles. They were fine after that. maybe just a coincidence.

Brand new calipers, new fluid, new discs and pads and they'd be warped from road use after 30k? Don't think so.
3 of us having this problem, pretty sure it's the pads.
Plus because it comes and goes, it's not a disc issue.

Dress the disc face to remove the transfer layer and changing compound should fix it.
