I have a 96 SR5 4Runner with the small brakes. I want to put the bigger 313mm rotors and calipers on. With the other calipers bolt right up?

 

The Tundra Brake Upgrade (or TBU) requires rotors, calipers, 16” wheels (check the TBU sticky for the list of wheels), and minor trimming of the dust shield.

 

I mean changing from the brakes on a 15 inch wheel 4Runner to the 16 inch wheel brakes on a 4runner

 

you have two options:

1. one is using the 4Runner 4WD calipers and rotors. you'll need 16" wheels as well as the calipers, brake pads, & rotors. The calipers have the stamp S13WM. Yes, the 4WD (bigger) calipers/rotors and brake pads is a direct bolt-on
2. The Tundra Brake Upgrade (TBU). This require the use of the calipers, brake pads, & rotors from the 1999-2006 Toyota Tundra. There are two caliper types: the bigger 13WL or 231mm calipers and the smaller 199mm calipers. The smaller caliper is the original caliper from 1999-2002. A TSB was issued the the calipers were upgraded to the bigger 13WL caliper. The rotor size didn't change. For further details, see the sticky on this upgrade.

 

thank you that’s exactly what I was looking for but i already jumped on the 4wd calipers and rotors
