[Shop-talk] squeaky brakes

[Tim]

I replaced the rear brakes pads on my daughter's 99 Toyota Solara today 
in hopes of eliminating the squeal when she backs up. They were in need 
of replacing (pretty thin on one side) but the squealer was not making 
contac. I didn't turn or replace the rotor since it was the rear AND 
they were in good shapes still.

After I was done I took the car out and it did not squeal on me, even 
during varied speeds backwards. Well, I just heard that they are still 
squealing at slow back up speed on my kid as she was leaving just now.

Any idea why?

shop content: I was in and out of my shop getting tools, etc.

Thanks.
