Brake Disc Caliper problems of the 2005 Toyota 4Runner

Noticed after just purchacing a used 4runner fro a Toyota dealer ship that my brakes seem to be making a lot of noise. Went to my mechanic and he told me that the front calipers on both sides of the car were frozen due to rust and that he has noticed this issue with multible sequoias and 4runners. Had to have the whole brake system repairs costing me over 1000 dollars.

Tl - the contact owns a 2005 Toyota 4runner. The contact stated that while replacing the brake pads he noticed that both front calipers were not working properly. The contact decided to replace the calipers. The manufacturer was made aware of the failure who did not offer any assistance. The vehicle was repaired. The VIN was not available. The failure and current mileage was 50,000. Pmb.

Front brake calipers had to be replaced because they were frozen.

Heavy vibration noticed when attempting to brake at speeds above 40mph. A reduction in braking feel and power was also noticed. When I went to examine the brakes, I found that both of the front brake calipers had frozen lower pistons. Had to replace both front calipers and rotors as well as brake pads. Found this to be a very common problem on 4th generation Toyota 4runners. . Read more...

When I tried replacing my brake pad, I noticed that the front caliper piston is frozen and I could not retract it. I ended up replacing my front caliper on both sides due to this. Both front driver side and front passenger side caliper is frozen. 1 piston on each caliper. I believe this is a safety issue and should be addressed quickly to avoid future accident. I have my receipts when I replaced it if you need it. Thank you.

My 2005 Toyota 4runner has had issues with front brake calipers seizing up. With roughly 60k miles on it, I had to replace both front calipers because the lower inner pistons were seized. I replaced the calipers with re-manufactured calipers. At 100k miles, I had to replace the front calipers again for the same reason. After searching on the Toyota 4runner forums, it appears that this is a common problem. The local Toyota dealership was unable to offer anything other than replacing the calipers at my cost. I called the Toyota customer service line and reported the problem twice, but they were also unable to do anything. They blame road salt for the issue. My other vehicles, as well as those of my neighbors/friends/coworkers, have operated in the same conditions, but haven't had this issue. Thus far, I haven't had a complete braking failure or incident from the issue. I've noticed the issue when the rotors warp from the constant heat and replaced the calipers. I'm concerned over the issue and Toyota's unwillingness to address the safety concern.

-the contact owns a 2005 Toyota 4runner. The vehicle was taken to an independent mechanic for routine maintenance. The technician detected the left and right front pistons were frozen due to excessive corrosion. The vehicle was taken to an authorized dealer for diagnostic testing. The front brake calipers required a replacement. The estimated cost for repair was $835. 00. The contact was displeased to know the manufacturer refused to be financially responsible for the total cost of the repair. The manufacturer offered to cover fifty percent towards the service repair cost. The vehicle had not been repaired at the time of the complaint. The failure mileage was 50,000. The current mileage was 56,000.

Front brake caliper "frozen", both. Brought vehicle to several independent brake shops and all said that it is a "common problem". Toyota dealer would not repair at no charge and in fact wanted about twice what the independent shop charge.

Front brakes pistons seized to rotors and will not release. Vehicle would barely slow down. Called Toyota hotline and they said there's nothing they will do to help fix the problem. Called dealer and they are well aware of the problem. They said they have replaced many front calipers and this is a common problem for 2004 and 2005 4runners. I almost lost control and crashed car when the brake went out and Toyota can't even help fix there faulty products. Vehicle has 85k miles. I counted over a dozen similar complaint on NHTSA website regarding 04 and 05 brake calipers seizing. Calipers should be recalled, this is just as dangerous as the sticking gas pedals they put in the new cars.
