In May of 2012, with approx. 50K miles on the vehicle, I had brake service performed on my 2007 4-Runner SR5 Sport 4WD. Pads and rotors replaced on all wheels. At 5,000 mile intervals after I brought the car to the dealer for oil changes and "inspection" of the brakes. A few days ago, at 75,000 miles I brought the car in for 75K inspection and mentioned a leak at the right front wheel which I suspected was brake fluid. Dealer called to say I had 2 front calipers frozen; replaced front calipers, all 4 rotors and pads and hardware. I asked for the replaced parts to be returned and verified that the calipers were indeed frozen, probably due to corrosion of the guide pins, but that the rotors were within spec and not pitted. The pads were scarcely worn. I live in an area where the winters are harsh and where roads are salted. Nonetheless I have never had these many caliper-related problems with any other car - save for a Ford Contour. I had heard that Toyotas were reliable. I'm beginning to wonder.

Front right caliper froze. Had to replace both along with rooters and pads. 4k later the rear did the same thing. Initially had to replace calipers and pads at 35k. So much for Toyota quality. My tundra is hAving a similar issue.

Same issue as others reported here. Purchased vehicle used in '12 with 104k miles. When replacing my brakes and rotors I discovered the same problem- both front calipers had seized. Only one of the pads was worn while the other was untouched. Clearly the person who replaced them last was aware of this problem and now it has become my problem. Hopefully it won't become a recurring issue like others have reported.

I've already replaced the front calipers on my 4runner at 40k and 52k miles due to seized pistons. Now again at 66k miles the same old symptoms are showing up. Pulling to the right when brakes are applied, HEAVY brake dust deposits, blued (burnt) rotor and pulsing noise and feel on braking. I'm positive again it's the same seized piston issue. It is quite obvious this is a design flaw for which my Toyota dealer is happy to charge me $1,800 to replace each time. When I asked him about why they would fail so soon, he responded, "It's due to the high corrosion rate in the north east." I'm done with people treating me like I'm stupid. The internet forums are FILLED with testimony of personal experiences of 4th gen 4runners having this issue and Toyota doing nothing about it. I'll be buying Nissan or Honda next time.

Front caliper seized vehicle was pulling to the right as I drove and applied brakes. I simply replaced them myself.
