Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety. Notes: Although it has a stellar record in terms of vehicle problems, initially the 4th generation (2003 - 2009) 4Runner didn't earn our top "Seal of Awesome" rating because it received poor crash test ratings for rear impacts. However it's proven to have one of the lowest driver death rates out of all vehicles (not just SUVs), so we've bumped it back up to our top award.

Same problem the calipers are frozen up again. I could tell the brakes were not real strong in the recent weeks. Had oil changed at the dealership today and the mechanic came out to speak with me. He said the brake pads are wearing unevenly. Which tells me that the 5 year old caliper is frozen, causing no wear to the pads. I replaced the f/r a few months back. If you own a 2003 Toyota 4Runner I would have the brakes checked regularly . I probably have brakes on 3 of the 4 wheels. My fix, I now have a 2016 4Runner in my garage. Just trying to milk all I can out of the 03.

Bought new V8 SR5 in May 2003. Never had any problems. In 2011 I went in (dealer) for an oil change and brake pads. Service adviser came out after 2 hours and informed me "we have a problem". The front calipers were so rusted that they would not go back on. So a day later and $1100 lighter I drove off.

In Dec. 2015 the front right caliper did the same thing. My brother is a mechanic I took it by his house, popped the tire off and it was frozen again from rust. Went to Autozone bought a new caliper ($85) and he put it on. He thought it was a design flaw, somehow the calipers get over heated causing the metal to weaken causing the rust.

Now I'm at 205K miles and this and a minor cracked dash are the only problems I've ever had. Not bad too bad.

Ive been through 3 frozen calipers on this vehicle. Got to be a bad design. They are fairly easy to replace yourself.
