Depends on model.
If you have 256mm brakes which are fitted to later 16v's, you will need to remove the carrier.
I think this is what you have fitted to yours. The 2 bolts are 17mm and are NOT self locking type, but are very tight.
In all honesty you may need some pretty beefy tools to get the bolts out, depending on how long they have been on the car. This is because the bolts tips actually stick out the other side off carrier, so corrode like f**k. Might be worth checking this.
Hope that helps.
