i just changed out my old front brake pads for new ones. but now im hardly getting pressure. they are really tight on the rotor right now and the wheel is kinda hard to spin, and when i ride, squeezing the brake doesnt stop the bike very fast. the brakes are applying, but not very strong. i tried to bleed the brakes just in some random case there happens to be a little air in the line. but unfortunately the previous owner stripped the screw on the MC so i cant take the cap off. (ill eventually be able to, just dont feel like going though all that work right now. its reallllyyyy stripped) can i still bleed the lines with the MC cap on? also, when i squeeze the brake, the front right caliper moves a little as it tries and squeeze the rotor, so i know im losing a lot of stopping power there also. any advice?
