braking question
hey guys...
I have a 2000 s2000, and I am from Minnesota. The winter gets really cold in here. whenever the car is cold, and I reverse the car and "brake", there is a sound of knocking sound from the brake. but it doesnt happen when I go forward, and it doesnt happen when the car is warm...it happens in cold weather and raining day. any idea ???

Its probably just the rear brake pads "moving around" a little.
Are your rotors a little rusted when you drive away?
Do you apply the parking brake when parked?
(if you want you could use 1st gear as a parking brake and leave the "real" parking brake off)
When you drive away with a warmed up car, you hear no clicking sound from the rear, right?
Or if you change from driving forward a little to reverse.
If so, then the axle nut may need to be retorqued to the new higher spec. being IIRC 298 Nm / 220 lbf/ft.

"Pad Shift" is the most common reasoning the dealerships will use, as that involves a $0 fix on thier part. More often than not, I see the Spindle Nut as the culprit needing attention. Usually just a matter of removing the nut, greasing and re-torquing.
Granted, our OEM rotors will rust quit quickly after exposure to moisture. The "snap" sound that occurs only at the first movement is the pad breaking free from the rotor.
However if the sound occurs every time you change directions (from reverse to forward) you might want to eye those spindle nuts.

and if i go forward a little and reverse, it also still made the sound...
