I have a 96 miata and had a 95 millenia before. Now I have an 09 mazda 6. It is dues for rear brakes and apparently there is still no repair manual out for this model. Are there any surprises when changing the rear brakes? It looks different from the miata and millenia and I'm hesitant to start without some kind of reference. Is there someone who has posted a step by step rear brake change? Google can't find one so I thought I would try here. Thanks!
