91 Legacy FWD shudders/vibrates under braking; ABS light on.

[cal_look_zero]

I managed to sell the Legacy I bought to flip, and the guy called me up because the car is shuddering under hard braking and the ABS light is on. Is there a chance that the ABS is freaking out and causing the vibration/shudder, or is it more likely warped rotors and/or blown struts? I'm going to help him get the car squared away, I just want to know where to start because we'll be putting PnP parts under it.

 

Personally, I'm leaning towards struts, but if it's as simple as disabling the ABS circuit, then I'm all for that approach.

any 'buzzing' sounds right before starting the car? I think there was an issue with abs pumps from around that era.

 

have him take you for a ride and demo his complaint.

I never noticed anything, but the car has some electrical quirks from a spaz PO and rodents.

 

Would pulling the ABS fuse harm the braking system at all?

Bumping. I gotta work on this turd tomorrow, would prefer to keep it simple if possible...
