07 TL making squeaking noise when accelerating and braking. When car is braking, the noise is quite loud and high pitch. Whiling the car is rolling, the sound goes a bit quieter but is still there. This only happens on the left back wheel area, The other 3 wheels have no sound at all.

 

a concept i learned recently; Visual intelligence!

this means; you or someone will need to look at the rear brake caliper to find clues on what the problem may be!
perhaps it's a stuck rear caliper; we dont know because we cant inspect the car...Pull the wheel and find out !!!!!!!!
