Ive never really had a problem with any pagid stuff ive fitted to mainstream cars, they are probably not as good as everyone thinks but seem reasonable quality for most applications. I did hear they were ecp own brand these days.
They are part of the Tmd friction group which also makes mintex and textar.
Id probably look towards the brembo stuff ecp sells for the Gti although i do hate using them as the sales are a joke.
I heard something similar - that ECP had bought the rights to the Pagid brand. And that some Pagid branded stuff is made in China. Not that all things made in China are crap, but you expect something else when you buy Pagid.
Anyway, it didn't stop me buying Pagid discs and pads from ECP (using the 'how bad can they be?' logic), and sure enough I found out how bad they were.
I'm not ruling out operator error - there's a chance I did something wrong when they were bedding in - but I didn't treat them any differently to any new discs and pads I'd had in the past. And these aren't fancy pads with specific bedding-in procedures required, just standard spec kit.
I now have a big wobble if I brake hard from speed. Whether it's pad deposits, or the discs are actually warped, I don't know, but I'll need to get them skimmed and hope it does the trick. The brakes function very well at lower speeds, it's just when 'hauling it in' I have the issue.
You live and learn!
