Hi, I bought a used Raleigh 5.0 with disc brake on both wheels, the rear is locked when the brake is fully engaged. I have not used it yet, I realized this when trying brakes and changes to register things to my liking. At the time of buying it everything was going. I did the tests to test the brake out of the frame and also placed but without the disc, it seems that the disc makes it lock, something very rare. I haven't had bikes of this type for 13 years and I never had discs. Can anyone tell me what is going on? greetings and thanks PB170106.JPG [1.32MB] PB170105.JPG [1.61MB] PB170104.JPG [202.65kb]
