So about a couple weeks ago, my brake pads were contaminated so I cleaned them up using isopropyl alcohol and it seemed to have gotten rid of my horse-like squeal noise coming from my rear brakes.
Today, I went out to ride and after the end of my ride, I could hear the wretched sound coming again. It's not as severe as the first time, but it wasn't this bad when I cleaned up the pads.
What I'm wondering is: is my brake fluid leaking in the rear cable that's attached to my brakes? (See picture) This picture is after my ride before I cleaned this black stuff off my brakes (after I washed my hands)
Second question: How do I tell if my rotor + brake combo is unaligned? The rotor does not spin wobbly, but I noticed that some of the metal that is close to the rotor has scraped off!
scraped off metal where the letter "W" is:
my alignment on rear rotor + brake (is this because the angle of the photo sucks? the more I look at the rotor from any angle in person, it looks unaligned!):
my front rotor + brake seems aligned. you can see the spacing barely:
Thanks for the help. I've been getting into maintaining my bike to make less frequent visits to the LBS, but if it's something I can't handle, I don't mind taking it to the LBS.
I'm not sure if I want to go ahead and do this (and if it's even necessary at this point), but I was going to loosen my rear brake caliper, turn the wheel, squeeze the brakes, and then tighten the two bolts.
