2007 SR5 Brake Recommendations
 

Looking for input regarding brakes. Have a few specific questions and details I'd like answered.

Current
Tires: P265/65/R17
Calipers: 13WG
Rotors: 319mm

1. Will someone explain to me the 4th Gen Brake issue? Do the calipers seize "open" or "closed" when it happens?
2. Are the PowerStop kits any good? I'm eyeing the Z23 kit from them.
3. What other parts would you recommend outside PowerStop, and why?

I don't tow. Unless someone can heavily convince me otherwise, I see no reason to upgrade rotor size. What I have (factory originals) have been good enough for the 2 years I've owned the vehicle. If the PowerStop kit or equivalent upgrade is an upgrade in terms of performance, then it will be better than what has worked for me.

The KC138 kit is $531.89 after core on RockAuto. I guess I'm about $500.00 on the budget for this project. I could cut that in half if I just do pads and rotors. So if I do calipers, that should eliminate the "4th Gen Brake Problem", correct? As I understand, it's an issue with the calipers.

Also, what about this kit?

Shaves a few hundred off. Would these calipers eliminate said issue? After reading more about drilled/slotted rotors, it seems some state that if you get dirt/mud in them then they don't last very long as a system.

Thoughts?

I did mine a few months ago and I cant overstate how glad I am that I upgraded to the bigger rotors from the sport model. Just the difference in pedal effort is amazing. Now when I drive my Tundra if feels like there's something wrong with the brakes. I went with Cardone calipers, Brembo rotors and Akebono ceramic pads. I looked at those Power Stop kits but the fact that they only have a 30 warranty killed that for me.
