"Check Brake Lining" sign on & brake light on - Guidance Pls

[rufryder]

I was backing up my car in the driveway, with steering wheels turned all the way, I heard a click (think on the front of the vehicle) and then immediately I have the brake light sign on & the LCD displaying, "check brake lining."

Now, how can I check that? Is it DIY? Link? step by step guide.. After doing some research, it states its right next to the brake sensor & check again, however I think due to the noise, it may have cracked or something. So, which part do I purchase & be prepared for it if it needs be. Oh, and, is it still safe to drive with that light?

side note: I have done the brakes myself about 5k miles ago.

Thanks for your help in advance.

If you have done the brakes, did you replace the wear sensors? If not they may be reading bad again.

brake linings = brake pads. Check your pads. They probably need to be replaced if you didn't do all 4 brakes in your repair.

If so, you probably popped off, or installed incorrectly the pad-wear sensor.
