Motorcycle Brake Fluid Flush: No More Brake Squeal!

The front brake on my 99 Yamaha YZ250 was making an annoying squealing noise even though the brake pads and rotor were in great condition. When I removed the master cylinder reservoir cap, I discovered the brake fluid was extremely dark, contaminated, and coagulating around the reservoir. In this video, I show how I flush the front and rear brake fluid on my 1999 YZ250 using a simple method that helps prevent air from entering the brake system, eliminating the need for a traditional brake bleeding procedure afterward. 0:00 Introduction 0:16 Squealing Front Brakes 0:42 Nasty Brake Fluid found (cause & Effect) 1:19 Tools & Supplies Needed 1:59 Front Brake Flushing Procedure 5:02 Rear Brake Flushing Procedure 7:01 Results & Final Thoughts Fresh brake fluid is critical for proper braking performance because brake fluid absorbs moisture over time, lowering its boiling point and allowing corrosion and contamination to build up inside the brake system. Whether you ride a motocross bike, enduro, dual sport, or trail bike, this brake fluid flush procedure will work on most hydraulic motorcycle brake systems.
