I have Wilwood Dynalite brakes on the rear of my Savoy and they have drilled rotors(not my choice I just got a smoking deal on them)that make noise whenever step on the brakes. I was just wondering if this is a normal sound that will go away after a while or are they just like that. I'm probably just going to get a new set of solid rotors and see if the noise goes away. Anybody need a set of drilled rotors Thanks Gus

Almost kind of a whirring wooshing noise when I apply the brakes hard or easy. I can tell by the noise the pads are just starting to make contact with the rotors. My exhaust is very loud and I can still hear it over the stroker with 3" 2 chamber 40 series Flow Master mufflers. Wife and I went for a 40 mile cruise last Saturday and she asked me what that zzrrr zrrrr zzzrrr noise was and thats how she described it She said she could almost hear the holes in the rotors going past the pads.

Solid rotors have no place for the air in the holes to go. So the air is trying to push the pads away from the rotor. Thus the noise. Vented rotors let the air go thru the holes, and thru the middle of the rotor, then out the outside diameter. No pushing out of the pads.

Yeah It sure is annoying at every stop so I'm stopping at Summit and picking up a set of solid rotors and bolting them on and re-safety wiring them AGAIN All in all though going from 4 wheel 10.5 drums to 4 wheel discs is amazing effortless stopping. Gus
