Recently I bought a mountain bike with hydraulic disk brakes.
But when I ride it the front wheel makes screaming sounds, possibly from the disk brake.
I contacted my local dealer and they helped me adjusting the brakes, and I even learn how to do it also.
But it seems the problem happens more than once, every time after I put back the front wheel and start riding. The problem is frustrating; I need about 5 minutes to adjust the brake and tyres every time.
What can I do, should I replace anything?
