help (Knocking sound on left rear)
 

Knocking sound on left rear..I know it's time for new pads but dont know if Thats causing the noise...it's really bad when coming to a stop on neutral at low speed...

Not sure due to the limited info, but if you know your due for pad replacement, you're running the risk of ruining your rotor if it's metal to metal contact. If you need to replace the rotor on one side, you should replace on the other side too....my point is, the cost is quickly rising.

Agree man I can hear metal grinding already changing pads 2morrow..hope rotor not damage..my thing is never heard a knocking sound like that..
