Hi
Im in the process of sorting calipers aswell and had the same pondering question fix or buy new. In the end i worked it out at costing up to ?25 per caliper to rebuild with OE parts. So i decided to go for the britpart calipers ?56 each. I have them fitted on my 110 and dont have any issues with them. Got these fitted at lamacha last febuary done 8k since. Pleased for such a cheap part.
