I have a 2001 Hyundai Accent, 30,000 miles on it.

I just had the large 30,000 mile service a few weeks ago.

For weeks now it's driven great, but a few days ago it developed a loud clicking/popping sound from one of the rear brakes.

It doesnt make noise while turning so I'm sure it isnt worn wheel bearings or CV-joints, it also doesnt occur when I'm just driving, so I'm sure it's not a rock or nail in the tire.

Problem is sometimes it makes the noise and sometimes it doesnt. There's no reason to it, whats stranger is sometimes it'll happen an entire drive, then when I park the car and drive later it'll go without making the noise at all.

I'm wondering if a pad is loose, but I dont feel anything odd through the pedal, it still holds tight and there is no vibrations.

Any ideas on what it could be?

Thanks!
