Hi all,

I'm looking to replace my Brenbo front brake discs and pads. Could someone tell me what the original OEM number of the Brembo brake discs are and the diameter of the disc.

I've been doing some searching but seem to be getting different answers!

Also, where are people getting there's from for the cheapest price.

Thanks in advance. Ian.

I got my last set on Euro Car Parts, keep an eye on them as prices can vary widely!

BREMBO Prime 09.9477.23 Brake disc for AUDI A4
Item number: 09.9477.23
Manufacturer: BREMBO
EAN number: 8020584947722

Fitted these 2 months ago in place of original discs.
Pads I don't know, sorry, as I went with Ferodo pads. Squeaky but very good.

There's far better options out there than OEM discs. Not only are OE discs pricey, the holes fill up with gunk making performance very average.

Check out Reyland Motorsport. You can get OE size for far less than OE money, in various grooved formats (importantly not drilled). Or you can even upgrade to a larger size whilst retaining use of the OE caliper for not much more than what OE discs cost.

I would never, ever go back to OE discs after using Reyland and hearing about other great alternate options too. Braking performance has been transformed.

I was just looking at the Reyland discs today. Can I just use my brembo bells and replace just the rotas?

I should have added that I really wanted to go Reyland and would have but the lead time was quite long and I needed the car sorted sooner because I didn't realise it needed discs when it did. Requires a bit of planning next time so if you have that luxury definitely consider Reyland or Tarox.

Yes you can, with the 365mm option priced at £374 about half way down this page - http://www.reyland.co.uk/audi-front/
