Grinding noise from both ends

Here is my 2005 Ninja 500r.

I've been having some trouble with it. It is my daily driver to class and was wondering if anyone can help with my two problems

1) I recently changed the front brakes and up front there is grinding/ scooping noise about once a rotation. I don't believe it has anything to do with the rotor because if it was wouldn't it shake while braking? It's been about 3 weeks so they should be bedded right?

2) Also there is a grinding in the back when I brake. I believe I need new brakes in the back and found some pads online for cheap. However I cannot get this bolt off for the life of me. I can get the top one off just fine but the bottom is stuck


I even twisted my hex key trying to get it off



Have any ideas how to get it off? I wish I could use a socket wrench. I called the local motorcycle shop and they quoted me $100 for changing it so taking it somewhere is not really an option when I can do it for less than $15

Any help would be great! Thanks!

 

I would bet there is pad material built up on the front rotor in that one place. Scuff the rotor with some fine sand paper and see if it helps. As for the back, get some socket hex wrenches, and try that with an impact and the standard liquid wrench of your chooseing, or drill it out and get a new bolt.

 

Ill try and sand the rotor see if that works. Hopefully it does because it's annoying and it makes me feel like I have shitty bike with low integrity. I didn't even think of buying socket hex wrenches! Will do that too

 

If you haven't done it grease the front caliper pings and make sure the caliper is floating. Also like the other player said scuff your rotor, I had the same basic issue and a new rotor was my only fix.

 

Have you tried putting heat to the bolt your struggling with?
