    Hello,

    I have a 2004 4-runner sr5 v6. In June of 2015, I noticed that my driver's side rear wheel was heating up and I could smell the brakes from that wheel only. The caliper was replaced although they really could not find anything wrong with it. About 6 months later, the problem returned on the same wheel. This time they replaced the caliper again at no charge and also turned the rotor and replaced the small brake line feeding the rear driver's side wheel. New pads all the way around too. Problem went away again but has now returned again and 14 months later. This time the shop wants to replace the caliper again with a Toyota part this time.

    I worry that something else is causing this, but what could it be? Three bad calipers?

    Should I have them replace with a Toyota part or could this be something else?

    It does not lock up on the rotor and I don't even notice it until I smell the brake and can feel the heat. The shop said about 80 degrees hotter than the other rear wheel. Brake pads are not worn more on this side either at this time. It is also intermittent. No obvious noise or tugging from the rear. Any help appreciated.

    Thanks.

    make sure if you use the parking brake that it is fully releasing on that side all the time .

    jack the wheel off the ground and press brakes to make it "grabby", now go to back of caliper and open the bleed screw and see if that frees the wheel up, if it does then your brake hose needs to be replaced. (note - if you find one hose is bad replace all 4 of them)

    brake hoses swell up on the inside and can close themselves off acting like check valves when they get old.

    its so common for mechanics to fix the bad parts instead of finding the problem that caused them to go bad
