I have a 2001 RX 300 AWD and I was doing a break job on them. I first replaced the rear rotors and pads and bled the lines. Then the next day(did not drive during whole install) I started the front. Again I replaced the front rotors and pad and bled the lines. I go to drive it and it has a horrible screaching sound. Now I know there is period for them to wear down that small bit but this was awful and it felt like one of the wheels was loose.

I take it back to the garage and the rear lugs are all loose. ( I have been working on cars for years and I did tighten them in the air and then when on the ground) I checked that the rotors were lined up with that rubber plug and the larger whole on the the part that has the lugs. I lined both sides and tried to drive again.

Now I can only drive it about 10 feet and that is with giving it gas. You should be able to have it in drive or reverse and it moves by itself slowly but you need to really give it gas.

BTW the parking break is off.( I checked that first) I really need some help soon. My wife comes home tomorrow and she will need it. Any help would be great. Thanks everyone.

I would check to insure the pads are installed correctly. There is an inner and outer pad. The inner pads have a "squeel" pad attached already on new Lexus "rear" pads. The front needs to be removed and reinstallled on the new inner pad. Additionally, did you find metel shims under the original pads? They needed to be cleaned, greased with caliper grease and reused. Were you carefull to reinstall the pad edge stainless clips correctly and grease the pad where they contact the caliper and clips.
Sounds to me you may have misplaced a clip and it's contacting the rotor. Take a hi intensity lamp and check the rotor surface for and contact other than the pad itself. Lastly, insure you torque the lug nuts to 76Ft lbs. Too tight may warp your new rotors.

 

Well he a$$holes at Advanced Auto Parts gave me rotors for a 2wd and not an awd. The offset is like 1/4 bigger.

So thats my problem

 

Glad to hear of your resolution .. Different offset eh. I'll make a note of reference and be on the lookout when I need the rear rotors. Thanks !

 

Tip:

Always spin the wheel to see if it rotates freely after a brake/axle job. [you have to take additonal safety measures when you move trans in neutral and relase auxillary brakes]
