Brake Pad Surface Rust Squeak

Because electric vehicles use high amounts of regenerative braking, the physical iron brake rotors are rarely clamped hard by the brake pads. This causes a thin layer of surface rust to accumulate on the discs, creating a loud squeaking sound during initial morning stops.

Step-by-Step Fix Instructions

  1. 1

    Accelerate to 40 mph on an open road, shift safely into Neutral to disable regen, and press firmly on the brake pedal.

  2. 2

    Repeat this friction braking burnishing process 3-5 times to fully scrape the rust crust off the metal face.

  3. 3

    Visually check the brake rotors through the wheel spokes to confirm the shiny steel surface has cleared up.

  4. 4

    Spray brake cleaner fluid into the pad gaps to flush out stuck brake dust or grit.

  5. 5

    Remove the brake pads to apply high-temperature anti-seize lubrication grease to the non-friction slider clips.

  6. 6

    Replace the brake pads and machine or swap out the rust-pitted steel brake rotors entirely.
