hi guys when i drove my car in the morning yesterday there was a sudden pop in in the left rear like metal hitting metal i ignored it since its been doing that lately but this morning when i was driving the pop came again and this time after the pop it kept making noise like i had a flat but louder and more sharp like something is flapping/clicking after driving for like 3 mins the noise went away and the car was back to normal anyone know whats going on.

btw i need to adjust my e-brake the shop said its needs to be adjust cause when i take off my e brake and reverse it makes pop noises. mayb thats the problem?

thanks in advance guys
