Sounds like the rotors need turning.
mmm intresting they are new i would guess maybe 20 miles on them They had some surface rust on them. I didnt look but i cant imagine the rust still being there.
It's not the rust. It's the finish they were originally turned with. Any time you cut a rotor, you are cutting threads on it. If they are cut too quickly, those threads will put up a resonance and cause a hum.
Then maybe i should have them turned by someone who knows what they are doing.
Sounds like the same set up I used to sell. I was dealer for TSM. Sounds like rotor warped. Not sure what they use now but the last 2 kits I saved for personal use has FORD rotors machined for 8 3/4 Dana 60 fit.
Yea im not sure what the rotors are. I only know what the calipers & pads are from. I contacted them not to long after i bought them because the one piston wouldnt turn in. I wanted to know what the calipers were from. They told me they were a 1980s caddy
That kit looks completely different than mine. Yea im going to have to ask around & see who does it in my area if any.
Warped rotors will cause a pulsation. (50 years in the business) Rusty is correct, these rotors need to be turned (fine feed rate on the rotor lathe) and a non directional finish added.
I dont feel a pulsation. No mater how hard or soft i press the pedal If im going to take them off i just might as well get them turned
And that's good. I doubt they are warped. 340six said they were. Nope.
yea i know what warped rotors feel like. They are to smooth to be warped
He "MIGHT" could try like a rolok wheel on a die grinder and give a swirl pattern on both sides of the rotors. That might get rid of it. But most of the times, I've had to just turn them. Just like you said. Nice and slow.
