So the past month a "whoosh whoosh" sound would occur every time the wheel does a 3/4 turn. So naturally as I go faster it "whooshes" more frequently. Its not noticeable driving straight. When I turn it is louder. When I brake, it is very loud and you can almost feel it.

I found it is coming from the rear rotor, specifically the left one. Outside portion is great, inside of the rotor is a different story.





The other side is almost the same story just not as bad. Obviously I am replacing these rotors. And now I know where the whoosh is coming from. What I want to know is why this is that bad inside but not the out side of the rotors. I am a second owner to the car, and do not slam the brakes at all. I conserve my brakes. It is a 2011 so has a few years on them. But why does it look so bad compared to the other side?

 

That looks like the caliper is not functioning properly in that the inside pad is not making contact with the rotor. I wonder if the calipers are seized and therefore not applying even pressure on both the outside and inside pad. Perhaps when you change the brakes you'll figure it out as they are the 'screw in' type pistons and if they don't budge then that may reveal your issue.

 

Yea, I am wondering if the brakes are having issues. Thanks.

 

Is that a big old crack in the caliper mounting bracket i see?

 

ha. no it does appear like that, and when i first looked under it scared the sh*t out of me!

 

well, the bracket has to come off to change the rotor anyway, so it wouldn't be that big a deal if you needed to replace it.

 

if that is not a crack I owe you a chocolate donut ....

that SURE looks like a BIG crack to me

and I've done some brake work, metal work and welding . . . .

IME you can get rear rotors off without pulling the bracket ... front, different story.

 

Hope the shipping is worth paying on the chocolate donut. the angle in which I took the picture shows as if it is a pure slice through the metal. But it is not.

I am so glad we are on topic here....

 

When you remove the caliper make sure the pads slide easiely seems to me like a stuck pad or a broken pad. The shims need to be lubricated so as the caliper moves in and out so does your pads if there is rust they will not slide and they will stick
