So I decided to change my rear pads with on my Lexus08 IS250.

On both rear pad sets I had more inner wear. I installed the right rear with new pads. The left side and some imperfections on the inner rotor so I had the smart idea to put the old pads back on the left side to try and smooth it out. So my set up is right rear new fresh set of pads left rear old pads with 1/4 pad life left.

So I take it for a test and and holy crap the rotor was bright red and my wheel was piping hot on the right rear side where the new pads sit.

I was able to manually push in the caliper with a flat head with ease so I don't think the caliper is bad, the hose isn't kinked, guide pins are not over tighten.

SO the only thing I think is the 1/4 life pads are causing an imbalance.

Do you all think having one side with fresh pads and one side with 1/4 pad life could be causing my rotor to get cherry red?

thanks guys

You're suppose to replace both at the same time. Second, with more inner wear, sounds like your rear calipers may have some seizing issues.

XSV so my thoughts are when I get home I will swap out the old ones for the new ones in the box. do you think this will stop the overcompensation on the right side?

anyone ever experience this?

Are you able to push the caliper back and fourth? It should glide side to side. If it doesn't, it means that the caliper is seized and only the inner pad is making contact when braking since it is pushed out by the piston. In order to fix a seized caliper you can:

1) take it apart, clean out the rust, relube and reinstall
2) replaced the entire caliper

What I don't understand is how the pads decompress against the rotors after the are been applied to the rotors. They are not cluded to he two rods and the whole caliper slide the left and right.

Caliber is fine, the sliding ping is seized.
Same thing happened to my friend's car. Rotor pretty much broke into 2 pieces.

I didn't think it would be possible to tear up the rotor like that, if anything the piston would just died from overload.

Regarding the 2IS rear brakes, why didn't Lexus make caliper brackets like most other cars, just having the caliper without bracket makes it look tiny.
