Brakes problem
2003 Lexus RX 330 6 cyl Two Wheel Drive Automatic 105000 miles

I just installed new rear rotors/pads and the wheels are locked up! What did I do wrong? Do the rotors have to be positioned on the hub in some particular position?

Hi
Did caliper pistons retracte easily? Parking brake shoes not rubbing and brake off? Did rotor rotate after replacement but siezed after brake applied?
Let me know
Thanks for donate

The pistons compressed fine, parking brake shoes not rubbing, and brake is off. I since have taken the wheels off again and the rotors turn by hand. So, yes I guess they seized when the brake pedal was depressed and the car was running.

That's what I figured lots of time when piston is retracted dirt, pits on piston are moved into bore a couple brake applications piston will not retract

I'm going crazy here taking off and putting on the calipers and wheels. I replaced one caliper, Pep Boys gave me one good one and one with a squared side to the hole for the swivel pin. Okay, the bottom line is this: when the wheels are off - the rotors spin, when I put the wheels on (still up in the air or on the ground, they won't spin. Why can I spin the rotors by hand when the wheels are off but can't when the wheels are on the rotors? Please help.

Rim must be hitting caliper make sure caliper is seated and bottom hold down bolt in threaded hole.

Parts guys can do that always good idea to compare what they gave you with what you have.
