Ok so here is my question, I believe I have heard of it done, but I would like some input from people who know and not hearsay. I have lifted it and put way bigger tires, 315/75/16, So needless to say I have lost some braking power.
I was wondering if I could just straight swap Tundra calipers on it, or can I also fit the rotors with the 16in wheel still. I need more braking power especially when towing.

 

search... i did the 231 mm brakes with 5 spoke 2000 4 runner rims. sweet set up.

 

I used tundra calipers with sequoia brembo cross drilled rotors

 

If you don't swap for the Tundra the rotors too, you might as well not even bother.

It's all right here:

I've got the Tundra calipers and rotors with stock 16" split 3 spoke Toyota wheels, no clearance problems, and much better braking. I used the smaller Tundra set up, 199 mm I think. Mine's an 01 4Runner so I used 01 Tundra parts.

 

Cool,, So it sounds like the tundra rotors are the same diameter as the 4runners? if so then whats the benefit of swapping the rotors? I could just get some nice ones for the 4runner or something. I just went through hell getting these rims because of a backspacing issue when it was lifted so i don't want to get bigger ones yet. maybe when i need new tires but most likely not, i wheel this alot.

 

The only benefit you get is more heat capacity in the brakes because of the thicker rotor. Tundra brakes will not dramatically improve your stop distance at all and have almost no impact on brake torque or power.

Even if you had large pizza sized rotors and 8pot Alcon calipers, you're not going to see drastically shorter stopping distances over stock. And when you add big, heavy tires, you're just exasperating the problem.

Bottomline: heavy vehicles with lots of unsprung weight take longer to stop no matter what.

 

just read the link. awsome info thanks

 

Cross-drilled/slotted will do nothing for performance. Get yourself some good pads (Hawk LTS). I was going to go with Tundra brakes, but I wanted to give the 4Runner brakes one more shot. I am using Autozone Duralast rotors (2 year warranty) and some carbon metallic pads. So far, so good.

 

I have good OEM pads, but like I said I have 35's and tend to tow. The 4Runner brakes are not quite what I think they should be. I'm looking for the Tundra Parts right now for cheep when I do.. It's ON... also My wife just let m buy URD's 7th injector kit last night and a smaller pully.. cant wait to put that on.
