I am recently experiencing a weird noise coming from the front brakes (I suspect the passenger side). It only happens AFTER I remove my foot from the brake pedal. The noise would come up after around 0.5 second after full releasing. The moaning noise last about 0.5-1.5 seconds, and this peculiar noise does not come up all the time. It happens once out of about 4-5 times, rather irregular. It happens both at full stop and at slow speed deceleration, never at a high speed deceleration.
The vehicle is a 2015 VW tiguan AWD, I had a small incident on the passenger side door 2 years ago, but the noise only came up 3 months ago. Any one has any ideas?
