Tulis hears a grinding noise from the left front quadrant when she brakes. She also occasionalyl hears a “bubbling” sound when she first steps on the brake. The noise started after she had brake work done, and got a little better after her mechanic “sheared the bearings.” Tom and Ray think the noise is caused by the composition of the brake pads--Tulis’ mechanic didn’t use factory pads with the shims and paste--Tulis should go back and ask him to fix it for free, with factory pads.
