But I now have to reconsider the Perma Ceramic. Even though I clean the pins and relube well, along with the other contact points, I have had complaints from customers of squeeling and brake noise. Most of the cars I have done brake on though are the metal pin to metal bore setup, SO ????????????
.."squeeling" is mostly related to the type of pads being used and type of rotor surface...could also be coming from the caliper pins, but very rare for this to happen..lately, my only experience with all the cars in our family has been to use Akobono ceramics (HiPerf)in the fronts when ever possible..lube up the back of the pad and both sides of the shims to absorb or dampen the noise...pads are to be used on a freshly turned or new rotor..never a squeel from any of our vehicles..not even once over the last 4 yrs..
