I Have A Clicking Noise When I Brake, Thought It Was A Cracked Rotor, Replaced Both Rear --still Clicking , All U-joints Good & Bearing Good. I Even Took The Park Brake Lose To Bake Sure It Was Not Part Of The Problem?? Help I Have Had 6 Vettes 2-c3 And 4 C-4. Thk Bbb

I had a clicking on my front C-4 brakes. The pads were floating so I asked my local chevy dealers service Mgr about them. He said I needed to replace my aftermarket pads whith OEM pads from Chevy.I did so, and the problem was solved. I think I paid about $ 180.00 for the front pads 2 years agao. Good luck.
Danny!

floating pads sounds like that might be what it is.but going to the dealer ship will cost a arm and a leg.the local brake shop is cheaper with the same results.and why get a OEM stock pads for that LT-4 you could get some carbon metalic pads for less which will last longer checkout summitraceing.com for the prices i got some for like $95 and you could get a brake mastercyclinder balanceing spring for 20$ to prevent this from happening again.I got the pads installed for like 50-60 bucks.
