I think you mean copper grease , put it on the back of the pads , sometimes helps , thats if it is the brakes .
My 182's developed a squeak , only 3000 miles on the clock , i thought it was the pads so i copper greased em but its still doing it .Now i've worked out its the suspension so its booked into Renault in 2 weeks , for them to check it over and sort the knocking on full lock problem .
You could try phoning these for brake pads, i think we get cliosport dsicount also .
