I got back from the dealer yesterday after 5,000 mile service on my k-9. The rear brake goes a lot farther down before it feels like the pads are working. It needs to be adjusted. How do you do that. Also the brake lights are not coming on when I engage the front brake lever. Any suggestions on how to fix. Thanks in advance for any help. Btw I would take is back to dealer but it is 45 minutes away and very difficult for me with my work schedule to take it there.
