190 brakes V's standard cdt

[GordyB]

Hi, I'm sure the info I need is in here somewhere but for quickness....

..can someone please explain the differences between the standard brakes on a MK1 115 CDT and the "bigger" 190 brakes. I don't know if it's bigger discs, whether it's different pads or just the caliper brackets different to space them out a little, whether the calipers themselves are different - you get the gist.

Also, looking at pagid pad prices on ECP, I put my reg number in and it gives me 2 options with different sized pads and says to check which ones I need before ordering??

And lastly, who made the original pads when it left the factory? Are they still available?

Any help will be great

Thanks
