What causes brake squeal?

All four brakes have audible brake wear indicators. When the brake pads need replacing, you will hear a distinctive metallic "screeching" sound when you apply the brakes. If you do not have the brake pads replaced, they will begin screeching all the time.

Your brakes may sometimes squeal or squeak when you apply them lightly. Do not confuse this with the brake wear indicators. They make a very audible "screeching."

Occasional noise can be caused by the light application of brakes for a prolonged distance before stopping, or from high relative humidity. These are normally temporary and are considered normal brake noises not requiring repair.

Why must I have the brake fluid flushed from my system at certain mileage intervals?
  • Brake fluid is hygroscopic, which means that it absorbs moisture. And when that moisture finds its way into your braking system, it can corrode metal and seals.
  • Flushing the system with new fluid removes the condensation before extensive damage can occur.
  • When flushing the system, always use Honda Heavy Duty Brake Fluid DOT 3. If this specific fluid is not available, you should use only DOT 3 or DOT 4 fluid from a sealed container, but only as a temporary replacement. The use of any non-Honda brake fluid can cause corrosion and may decrease the life of the system.
