I started to change brake rotors today and noted that I have the cast rotor with longer hub flange and 1 1/2" lugs on driver side and the composite rotor with the short flanged hub and 1 1/8" lugs on the passenger. Well at least they keep the years right per side! I am only changing the rotors because the mil is at its limit and im getting a pad squeek. Otherwise i didnt have any problem. The hubs on both sides are still good. Question is will it be ok to go ahead and install new different rotors? Comp on pass side and comp on dr side. Will this cause any problems?

 

What year?

 

Its a 1999

 

I see i make a mistake in my initial post. I want to know if I can put cast on one side and comp on the other new? On the correct hubs of course.

 

Why not just put on the same and not mix and match?

 

OE spec for 1999 is Full Cast. Sounds like someone screwed up while replacing a single hub and bought the wrong one.

The difference between full-cast and composite hubs are the length of the studs to accommodate the difference in thickness between the rotors. I'm not sure if they're actually replaceable.

 

SALAD 99 is a mixed year on the front rotors, some has cast, some had composite. personally i would change it over to one or the other. keep in mind you will have to change atleast one of the hubs too.
