I put disc brakes on my 14 bolt and now have a small problem. After driving for a couple of miles they will start to make a noise, it is difficult to describe but while driving fast it sounds similar to the noise a mud tire makes while driving. While going very slow the noise sounds like when the brakes make a "groan" noise if you are stopped and release just enough pressure to roll a bit, and I can tell that it only makes this noise on a small part of the rotor, the noise gets loud then quiet then loud then... I used new brake hoses, rotors, and calipers and they aren't sticking. When I installed the new rotors the lug studs fit loose in the rotor holes but tight in the hub holes, so I know that the rotors aren't centered. The noise to me seems like a warped rotor. Do the rotors usually need turned before installing the hub/rotor on the truck?

DIY makes some that are a really good price. I got mine from Sky-Manufacturing because they wer bent the correct way and did not use the stand out spacers. I used the Caliper and rotors off of a 78 K20. Half ton and 3/4 ton Calipers are the same and will bolt right up. I used the Az-Kickin off road supply brake line kit. /forums/images/graemlins/waytogo.gif
A new rotor shouldn't require turning. You may want to pull it back apart and look at your pads. I have had them make a similar noise and the only thing wrong with them is they got diff fluid on them in the installation process. Other than that not sure what to tell you. Stud holes should have fit damn close and snug on the rotor.

Any rust between rotor and the assembly that it compresses against?
It sounds like (even though they are new) the brake lines may have internally collapsed.
Maybe a damaged hub causing the rotor to wobble as it turns?
Good luck /forums/images/graemlins/thumb.gif
