Thought I might start a little topic/bit of info regarding rear discs for the L502s Mira, since I've been asked by a few folks about obtaining them.
The discs themselves are a little odd, since they're not actually "just discs" rather, they're integrated as part of the hub. So, when purchasing a new disc, you're effectively purchasing a new hub at the same time:
(Pictures speak a thousand words!)
Unfortunately, the only place I've been able to source these disc/hub things from is Daihatsu themselves, in Japan. And since you can only get them direct, they're a little pricey (around £100 per disc, plus shipping from Japan - which isn't especially cheap since they're quite heavy).
You could potentially try getting a pair through the UK Daihatsu dealer network. Some branches are a lot more helpful than others. However, my experience with them has been very poor and they simply "don't want to know" or refuse to acknowledge that the L502/L510/L512 Series Mira's even exist.
Part number is as follows, for anyone who is interested. Weirdly, when Googling the part number, only two links come up.
Hopefully this helps some of you out! And I wish you all the best of luck if trying to obtain these through the UK Daihatsu parts network!
