Hi all, I am lucky to own a 05JCW and I have just upgraded to Wilwood big brake recently. Here are some of concern after the installation and hopefully I can answer in here.
it make some strange noise on turning when it is cold ( I am in CA so it is not that cold, but after it park for few hours). It does not matter which way it turns, It sounds like " wooo, woo, woo" (sorry I am not good at all on describe noise-) I have checked all fluids and they are all fine, the noise will go away after 10 min of driving (I guess its get warm up). My concern is if that noise is coming from the car or from the brake upgrade (when it is cold).

I also have the KW suspension on the car and the noise start right after suspension and brake installed (they got installed together). I did ask the shop to check on it but they did not find any problem

anyone in here having the same problem?

thank you all for this great web site.

 

Are the rotors slotted at all?
Was the Wilwood package new or used?
If used, I'd check trueness / straightness of the rotors.

it is brand new, slotted and drilled.
thank you.

 

When raising the vehicle and spinning the wheel (when cool / cold), do you get the same noise?
Does the "woo-woo-woo" occur once per rotation, or is it a constant noise?

- Erik

 

the noise only come on when turning, going straight without any noise. I was thinking it might coming from the power steering (but the noise goes away when car warm up). Once i drive it for at least 10 min then the noise will goes away and stay away till I park the car for more than a hour (when it cold down again).
Puzzling,
thank you so much for your help Erik.

Ok, that's different; what you have sounds like a tall-tale sign of a failing wheel bearing(s).
Locate the side and replace. Good luck!

good that is something I can check now. thank you Erik and I will update you once I take it to the shop. I hope that will not break my bank account.
thank you again Erik and have a great holidays.
