i noticed something odd on my rear driver's side brakes. the pad on the outside seems to have worn more than the inside. i was installing shims and don't remember seeing the same problem on any of the other calipers. i braked firmly from 45mph right before i got home and noticed the brakes in question emitted more heat than the other 3. anyone know if this is a serious problem?

maybe you need to bleed your brake system or caliper might be getting stuck

i don't know how i'd have air trapped in the system since i never took the brake lines off. if it's stuck how do i get it unstuck?

All i can think of, is maybe a seized brake caliper pins. What i would of done is lube the rear brakes pins on both passenger n drivers and see i that helps the problem out. Gs's are known to have seized caliper pins, both of my calipers seized one was proffesioanlly lubed and the other one was replaced by lexus.

damnit that's what i was afraid of...guess it's time to bust out the jack stands for the 3rd time in less than 2 months i thought they would have relubed the pins when they did the brake dust boot recall for me back in '09. could the lube have hardened already?

Well if the rubber bushing is not in place or has a hole in it, then this will be every 2000 mile maintance. Lube it up and check the rubber bushing for holes or cracks and make sure to put it into the caliper as it can get loose.

I have the same problem. Still somewhat unresolved. Lubing the pins helped.

how did you lube the pins?

check the pivot pin on the rear brake caliper.

I got Lexus to replace my rear calipers two months ago because of it. The recall in 2009 was to prevent this from happening. Sad to say for Lexus but they have had more rear brake pin seizes because of the recall procedure than they want to admit. It is not the removable slide bolt, but the lower pin that freezes. If your pin is frozen, then the calipers can't squeeze evenly, this results in uneven pad wear that get worse as time goes on. One pad is worn more than the other, and one end of the pad is worn more than the other end.

If frozen, call Lexus customer service and tell them you know that this is an issue and you want new calipers.

ok i just got off the phone with the nearest dealership and lexus corporate. corporate tells me i have to set up an inspection with my dealership and let them document it. the dealership wants $130+ just to look at it. CLEARLY something is wrong with the caliper but the dealership says that corporate may or may not pick up the tab if i have the dealership replace it. what do i do? maybe i should just go to an independent shop and install a whole new caliper?

130 thats if nothin is wrong or its been physically damaged abused. Do you have warranty?

got 88K+ miles on my car and had the brake dust boot recall done in feb '09 so i'm out of warranty either way

i love my car but goddamn she's starting to get fussy.

In you're case i would contact our good friends at sewellparts.com and see how much would a rear caliper would cost with clublexus discount. Personally without warranty i wouldn't even waiste my time trying to have them cover anything. Its hard enough for them to cover things while you are under warranty.
