Question about 2006 Kia Rio5
Hi can some one help before i go mad....recently bought a 2005 kia sportage auto 2.7 but front brakes making noise screaching,,had disks and pads checked both fine by 2 garages but told it could be the calibar that holds the pad ,told something inside rattles but makes screaching noise when slowing down gently on brake has them all greased up still no joy only for 5 mins driving time,any suggestions manyt hanks tony
On assembly of disc brakes there is an anti vibration silicone place on the back of the brake pads. The two surfaces rubbing togerher at a centain speed creates a high frequency vibration that at first is above your hearing range at the higher soeed you are slowing dow from. A the speed of the rotor rotation decreases, the frequency vibratio changes and the frequency falls with audible range. Like wiping a piece of glass with a paper towel. Ever wonder why paper and glass would screech?
The sound goes away with harder application because you are actuallly dampening/altering the frequency out of the range of irritability.This dampening compound is used in assembly at the factory and needs to be applied to the brake disc metal side when new pads are installed. This ultra sound is coming or caused by the brake psd that is against the caliper piston. This is because the pad against the piston has more center pressure than full surface pressure as the pad hasand any vibration is telegraphed th to Caliper. The compound I mentioned is a silicone that actually absobs and dampens vibrations when it dries. A rubber (siliucone) vibration sponge. Alot of mechanics, but not all, will leave this compound out of the assembly because it just another step and a messy one to boot, Or to put it plainly, laziness and the lack of knowledge of purpose and importance> Good Luck, having the pads replaced and properly installed will get rid of your screeching.-Ned-
