Z Bear

Rusty, thanks for the clarification. I am going to try your procedure for bedding but thought I should ask first: My wife has been driving on the 2nd set for noisy pads for week now. Will it make any difference to bed them this late after being installed or should we have the rotors turned again before we attempt the bedding procedure ? I should also add the very loud screeching sound pretty much only occurs when backing and braking. This does not happen every time. Outside temp or length of time the z has been parked doesn't seem to make a difference. Sorry for being so detailed, we just don't want to bed over another problem....thanks again, Jer

Rusty, thank for you input. When you said "The pads need bedding. 2 new set of pads and never bedded them." Did you mean you had the same problem with two sets of pads before you tried bedding ?

No. You had 2 sets installed. And they was never bedded properly. You need to take the Z out and bed the pads. Find a straight piece of road. Go to about 80 mph. Stomp on the brakes hard. Slow down to about 40 mph. Take the speed back up to 80. And repeat. Do this for about 5 times or until you get brake fade. Once done. Drive around for awhile until the brakes cool off. Don't stop until then. If you do. You will get a pad build up in one spot, and it will feel like a wrapped rotor.
