jon38iowa Posted April 15, 2008 Share Posted April 15, 2008 Hello, ? I have recently noticed a scratch sound from the rear brakes. It starts when the brakes are lightly applied and goes away after more pressure is put on them; moreover, it doesn't always do this, but, seven times out of ten uses it does. They have about 20k on the rear disks and at running my hands over them, both disks feel smooth. I am thinking it's time for new pads, but if anyone thinks differently, please post.Also, the car stops perfectly normal. Thanks in advance, John Quote Link to comment Share on other sites More sharing options...
keltik Posted April 15, 2008 Share Posted April 15, 2008 After sticking new performance pads in my Legacy ive noticed a similar scratching noise. Would be interesting to find out what it is. All the sliders and pins are greased nicely on mine and i know the brakes arent binding, its just weird how these new pads are much louder untill some pressure is applied compared to the OEM ones.

Yes, and the rear does have performance pads. But, it never did this over the past year and half of use. :-\ Quote Link to comment Share on other sites More sharing options...
idosubaru Posted April 15, 2008 Share Posted April 15, 2008 make sure there's no grit/pebbles stuck in and around the pads and caliper hardware. but it sounds like the pads are noisy. can you tell if it's one or both sides? Quote Link to comment Share on other sites More sharing options...

Therefore, the disks are likely smooth where the pad runs, but are probably rusty towards the hub and outer edge. That can be a cause of the type of noise you're describing; the edges of the pads can "bump" on the rust until enough pressure is applied. If you haven't done so, besides the more easily seen outer surface, it would be good to inspect the inner surface of each disk as well.

jon38iowa Posted April 15, 2008 Author Share Posted April 15, 2008 The noise sounds prominent on the passenger side. The rotors were replaced with the pads. No substantial rust is visible on the outside.... Our winter was brutal here. Perhaps sand has made its was into them. I think I will try a good power wash.
