1 edit | squeal noise from rear when braking at low speed In an effort to rid my 2000 Honda CRV of this sound, I recently had my rotors / drums turned and installed brand new pads / shoes. Made sure the proper areas were lubricated, etc.
To describe the sound, it's like a very faint squeal of metal rubbing, nails on a chalkboard (a metal chalkboard) very annoying. Only happens at low speed when braking lightly (can't hear it when braking hard)
Brake performance is great. I can't still help but think it's brake related (because it only happens when I brake) but perhaps it's something else.
Ideas to solve? |

1 edit | It seems like it happens every time. Before and after the brake job.
I'm going to test slowing down with the e-brake and see if it still occurs. |

If you have sintered metal brakes, it can occur with light braking. Nothing to panic about.

usa | I don't believe they are sintered. It happens with the e-brake as well.
I'm going to replace the drums --- perhaps they are warped. |

On the OP's street car? I doubt he purchased racing pads and found stainless steel rotors. Sintered pads would destroy the OEM cast rotors in a very short time.

Sintered Metal
Sintering is a process where metal powders are pressed together at high temperatures, rather than being bonded together by a resin like organics. Sintered materials are almost always based on copper, which during the process alloys with tin (to form bronze) or zinc (to form brass). Less commonly, iron is used as the base material. Graphite and ceramic components may also be added to moderate friction performance. Compared with organic materials, sintered pads exhibit higher durability and longer life under racing conditions. They have a very high friction coefficient, but friction modulation-a measure of consistent, linear response to increasing brake-pedal input-can be poor. Sintered metal is tough on discs, which often must be made from stainless steel to have any chance of long-term survival. Low-temp response may be poor with significant noise and dust levels. At present, this material class is generally best left to motorcycles or hard-core auto racers.

kudos:2 | Thanks for that, Doc. I was thinking about a bike I am giving a hand rebuilding when I wrote that. Brake pads are on that list, and on my mind. 
Nonetheless, minor squealing can occur with light braking.
