Hello,
Just found your forum and hoping to stay with lots to read!
I'm after some help diagnosing a problem: After maybe 30 mins of driving if i go down a steep hill the brakes are fine but when i release the brake at the bottom I can hear like a grinding sound as the wheel turns. If I completely stop and press the brake down and go again the sound is gone or leave it for a few mins, I have replaced the front and back pads and one of the back break calipers in the past 2 months but that didn't sort the problem. I dropped it in the garage to check but they couldn't find anything but as it only seems to happen when hot? What would your thoughts be and how would you diagnose which wheel it's coming from? Car: i30 2013
Many Thanks Ryan
