They changed the oil from my Magura Breaks for 56 €. It needs 10 minutes of work. Very expensive I think! I think he didn't answered properly to my questions and he not explained by himself what he has found out. He just said eversthing is working well now! I asked 'How long did you work?' and he said 28€ for one oilchange. But it is still not working properly, but better! I asked then why the screws of the bar are not out, like normal after refilling. I think he forgot to try to put the screws in the right position before refilling the oil. For what he took more time by himsel was to try to sell me Oakly-Sunglasses. I didn't feel well after the visit in this Bike Shop.
