Hey there guys
After driving my car stop-start for a little while, i can hear a scratching noise when the brakes are applied with usual force. it won't happen for the first few times i slow down, but it gets louder and more frequent the more often i have to slow down. more force on the pedal makes it louder as well.
normally i'd suggest the pads, but we've checked them all multiple times and they are not worn down enough to warrant replacing.
anyone have any suggestions about what might be causing it, and how i could fix it. it's not overly dangerous for driving, as it still pulls up safely, it's just irritating as hell and doesn't sound good for the brakes.
cheers

Only thing I can suggest is to swap pads on the calipers - this will reverse their direction....also rub their surface with sandpaper to roughen them up as maybe they acted strange during the "bedding in" process. Another thought - - are the caliper slides sticking.
Maybe it's just the pads you are using - one with a high metal content are noisy.

Cheers Hako, I hadn't thought about taking them out and swapping them around or anything. I've had the car for 3 and a half years and never had to change them, so I don't know how they did the bedding in procedure. I know some pads require a certain method of bedding in but I have no idea if mine did or not.
What do you mean when you say the caliper slides might be sticking? How could I tell and how could I fix it if it is the case?

I couldn't even tell you what brand they are so i have no idea bout the metal content. Never knew that but it's handy to know when choosing new ones.
Cheers again mate

have you checked the slide pins to make sure the caliper is not distorting ..?
