Jeff has a 4th generation (2003-2009) V8 Toyota 4Runner that is his daily driver. This is a pretty cool vehicle that he uses to haul around his family, is capable of off-road adventures, and has enough power to haul a race car on a trailer if need be. Lately, the brakes have been acting up, not working well, pulling, and causing high-speed shimmy when braking on the freeway. Doing some research, Jeff found that these are symptoms of a typical 4th gen 4Runner, sticking pistons in the calipers. Jeff also found out that a common fix is to upgrade the brake to the ones found on a 5th generation (2010-n0w) 4Runner. So with a little research, Jeff ordered up these Centric parts from Rock Auto.

|CENTRIC||12044175 (120.44175)||Rotor||$ 54.99||$ 0.00||2||$ 109.98|
|CENTRIC||12044174 (120-44174)||Rotor||$ 86.79||$ 0.00||2||$ 173.58|
Centric parts are pretty high-quality aftermarket parts, the rotors are all e-coated to prevent rusting and the calipers have all the hardware including anti-rattle plates and clips. The new front rotors are the same diameter as the original parts.
The new rotors are thicker at 32mm vs the stock at 28mm. This gives the rotor more heat capacity and fade resistance. You must replace the 5th gen rotors and calipers together. If you use the 5th gen calipers on the thinner 4th gen rotors, you can spit the pistons past the seals once the pads wear. This will cause a catastrophic loss of brakes!
