Stiff rear brake.

Hey folks,


I was really hoping you someone might have some advice for me. About 2 weeks ago my rear brake started becoming very stiff to the point that with all my weight I can only push it down by, at most, centimetre and then I actually have to put my foot underneath the lever to pull it back up. After a quick inspection I saw that pads were pretty worn so I've replaced those but the issue continued. I then took the pedal and lever off the bike and cleaned / lubed the spring that's attached to the lever in case that was sticking. That seems fine now but again my rear brake is essentially useless it's so stiff. I'm a novice mechanic at best but was thinking the next step would be to bleed the brakes? Thought I'd come here first in case someone had experienced this before or maybe had a better idea as to what may be causing it? When the brake isn't applied in any way, the wheel spins fine with no rubbing and I can't see any score marks or damaged areas to the rear brake disc.


Any help would be greatly appreciated!

Thanks
