I put the Empi disc brake kit on my Roadhawk a few weeks ago. Mounted the calipers on top of the axle. The brakes make a noise when I slowly push the brake pedal. If I get on them a little hard it doesn't happen. Every now and then they squeak a little. Other than the noise they work fine. I remember years ago I had a truck that the disc brakes squeaked on. Seems like I used some kind of spray. Can't really remember. Any suggestions.
