Sound from brakes perhaps a sort of owl (7)
I believe the answer is:
screech
'sound' is the definition.
(screech is a kind of sound)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for screech that I've seen before include "High pitched shout" , "Cry raucously; type of owl" , "Squawk" , "Yell" , "Sharp piercing cry" .)
