My daughter's 2000 Alero coupe began exhibiting brake pulsation at about
40,000 miles on the clock. Old dad suspected the front rotors were warped and replaced them and the pads, taking great care to ensure that the hub to rotor fit was clean and free of rust and bumpy imperfections. Carefully torqued the lug nuts, also. Then "burnished" the new parts per a procedure shown on a major brake pad manufacturer's Web site. The brakes worked smooth as silk afterward.Now, about 13,000 miles and 18 months later the pulsation is back with a vengeance.
I used Bendix rotors and NAPA ceramic pads the last time. One rotor was made in USA, the other in Canada, so my confidence in their quality was high.
If it turns out the rotors are warped again what brand or price range should I opt for this time? GM? Higher priced Bendix? Drilled and slotted? Different pads?
Is there something else I should be looking at for causing this recurrence?
