Is Toyota brake fluid dot 3 or 4?
Toyota recommends using either Dot 3 or Dot 4 brake fluid in their vehicles, depending on the specific model and year. The type of brake fluid required can be found in the owner's manual or on a label inside the engine bay or door jamb.
What is Brake Fluid Dot 3 and Dot 4?
Brake fluid is a hydraulic fluid used in vehicle brake systems to transfer force from the brake pedal to the brake calipers, causing the pads to press against the rotors and slow or stop the vehicle. Dot 3 and Dot 4 are two common classifications of brake fluid, with Dot 4 being the higher-performance option.
- Dot 3 Brake Fluid: Dot 3 brake fluid has a lower boiling point than Dot 4, typically around 401°F (205°C) for new fluid. It is suitable for most passenger vehicles and light trucks.
- Dot 4 Brake Fluid: Dot 4 brake fluid has a higher boiling point, around 446°F (230°C) for new fluid. It can withstand higher temperatures and is often recommended for vehicles with high-performance braking systems, such as sports cars or vehicles with heavy-duty towing capabilities.
It's important to use the correct type of brake fluid specified by the vehicle manufacturer, as mixing Dot 3 and Dot 4 fluids can cause compatibility issues and potentially damage the brake system.
