Hi there,
My brakes were in need of bleeding and I was going to do the task myself but found that when I went to bleed them I didn't have the correct attachment piece (I have the sram guide R brakes on my mountain bike). I took it into a shop and had them done. When I got it back they still seemed pretty unresponsive especially in the rear... I had the lever almost all the way to the bar before I was getting good braking. I decided to re-bleed them myself after ordering the correct attachment piece. When I bled them I was getting out oil looking bubbles into the syringe. I was just wondering if this is normal. It looked like oil and water, not mixing together. The brakes take DOT 4 or 5.1 and I was putting 5.1 in them. I checked to make sure 4 and 5.1 could be mixed prior to bleeding them just bc I didn't know what they used at the shop. My concern is that the shop used mineral oil instead and thats why they aren't mixing. Is there any way to tell? Its been a while since the shop did the work so I don't think they would be able to tell me if they made a mistake. They are also out of town from where I live so couldn't take it back into them. Thanks!
