1997 Civic EX
front has rotors, rear has drums
just replaced the front rotors and pads with all new ones from autozone.
after i took the car for a spin, i notice a moan/sqeal noise only when letting go of brake pedal. i opened the windows, and it looks like the sound is coming from the rear brakes.

does not make any noise when engine is off...

its more audible on the outside of the car...

note: i didnt have to compress the piston in the caliper at all during the process.
stopping power is good (normal).
brake fluid level was slightly above max before i started, and i didnt open it again, and no leaks

anyone come across something similar??

 

I get this as well with having drums.

might just be really dusty or needs ajustment.

disc conversion keeps this from happening

 

sound like the release spring for the drums are giving out. 2 way to fix rear disc conversion or spend close 80 on litlle springs to rebuild the drums

 

update: also does it when RELEASING e-brake

as far as the conversion goes... would i need to buy/order any NEW parts? or can everything needed be pulled off a donor car?
