2001 Toyota Corolla Repair Question
Shuttering in the front end when braking?
Answer
How many section of the rotor did you measure? Sometimes the runout might be within specs but they can still cause vibrations depending on where and how the runout is.
If it is the ABS, you would feel something at the pedal. Did you check the wheels, bent rims can cause that as well.
I tried it in a couple of places across the face where the pads run. I feel a little pulsing in the pedal but only slighly. The vibration is mostly in the front end and steering. I never thought of a bent rim. I have an extra set with snow tires on. I can change them out and see if that makes a difference. Would it also make sense to unplug a fuse to the ABS and see if that makes a difference?
Yes, you can try disabling the ABS to test.
You can swap the rear tires to the front for testing.
