Is wrong brake grease bad or should I clean it off?

Using the wrong lubricant on brake pads can cause rubber boot deterioration and trapped contaminants. It leaves you wondering whether you need to disassemble the brakes again to clean it off before it causes premature part failure.

Every workaround mentioned in the threads below. We haven’t tested any of them — and nobody here is claiming they worked.

  1. 1
    leaving the current grease on if it isn't causing noise
  2. 2
    pulling the pads apart to clean off the incorrect grease and reapply the specified type
  3. 3
    using standard silicone-based brake lubricant like sil-glyde
  4. 4
    Using multipurpose brake caliper synthetic grease for both applications
