The brake fluid DOT 3 and DOT 4 is hygroscopic, which means that it attracts and absorbs water. It can absorb water through microscopic joints and seals in a motorcycle braking system, and can absorb as much water as 2% or its volume per year. When the brake fluid absorbs water, it lowers the boiling point of the brake fluid, and the addition of water can cause the formation of corrosion on the components of the brake system. braking. Lowering the boiling point of the brake fluid can easily cause a brake system failure during a hot day in conditions requiring increased braking, and it is important that all motorcyclists include the replacement of the brake fluid in their normal maintenance.
Some motorcycles are equipped with dual disc front brakes, ABS and coupled braking systems, so the procedure may differ from the video procedure. It is important to always consult your motorcycle repair manual before undertaking any repairs.
