Forgot to Replace Rear Brake Expander Clips

Did you replace the pads on both rear wheels? Did you happen to re-lubricate the caliper pins while you had it apart? If not, you should take it all apart and re-do that part anyway (and put those expanding springs in there)!

The rear pins tend to dry out and this causes binding and excessive/uneven wear on the rear pads. I am still fighting this issue on my 2010. Look over the recent thread "frozen rear caliper" for some additional info (I just posted in it, so it should be near the top of the Maintenance forum).

 

Ditto!

Maintenance on the brakes for the Prius should be top priority. I plan on lubricating my pins every 25k so the caliber can move freely at all times. This will almost guarantee long wear life. Also, he mentioned the pads were worn to the metal, but his rotor was still new and didn't need replacing. Wouldn't the metal pad meshing to the rotor cause the noise? I will think the rotor should at least be turned. Just my two cents.

 

I am wondering if the sound was the wear tab rubbing (not the metal of the pad plates)?

 

I would get the springs back on. Easy to forget, I just about did once. And as long as it's open yeah clean and lube pins. Silglyde is good. Are you being careful to align the inner pad pin to be between piston face spokes?

 

Now, tell us about the "Pin/Maintenance" .....

 

I think the biggest reason for early rear brake wear is the pins binding up. If it weren't for that, I would expect the rear brakes easily go 100k+ miles.
