Warped rotor sound without warpage.

[londo M.]

Replaced my calipers and turned rotors, pads are fine. Brakes work fine with no pulsing but just before coming to a stop with very minimal brake pressure I get the sound of a warped rotor. The rhythmic wooshing. Rechecked that all pads and slide bolts are free. The sound does not happen all the time. I thought I had 1 bad replaced rotor when I found 1 piston went out farther than the other and re-replaced it but still gt the sound.

Take one wheel off at a time, then see if anything is loose. Try to wiggle various parts to see if you could reproduce the sound.
