I installed new brake calipers and pads in the front on my 1.7L 914 (1972) after I discovered that one of the calipers was sticking. The calipers were high quality rebuilds from PMB.
Now I have this super annoying grinding noise whenever the car is moving. The noise is like something is grinding against the pads. It is there no matter if I press on the brake (hard or soft or at all), but it gets a bit louder if I step on the brake. I suspect that the new pads are a bit wider than the old ones. When looking at my disks again today I noticed that there is some surface rust on them, about the first 1/4" both from the outside edge and from the inside. I know I should have had my brake disks turned when I changed the calipers, but did not do it. My question is: will this annoying noise go away with a bit more driving, after the pads wear out a bit, or do I need to remove the calipers again, take the brake disks off to be turned, and reinstall everything? Sorry for the low quality pic...  |
