How do I know what front brake discs I need without looking? (2 types)

[crickleymal]

don't discount eurocarparts.com website. That can take your registration number and from there tells you what you need. BTW, for what it's worth, I am not a huge fan of buying brake parts on line. Relatively heavy to ship and if bought prudently through a local motor-factors, rarely works out much cheaper. Shop around locally to see what you can find and remember that it's better to spend the money on your car's parts than it is their postage.

The only problem with ECp is that they list too many bits sometimes. Frinstance if I enter my Reg No. It comes up with about 8 different discs, not all of them the same dimensions. Some are vented some aren't, some have different diameters and heights and thicknesses.

I tried their online help and it was useless. Take your wheels off and measure was the only practical thing they said.
