If your brake master cylinder is failing, you may experience one or more of the following symptoms:

1. Soft or Spongy Brake Pedal: Pedal feels unusually soft or slowly sinks to the floor — indicates internal seal bypass
2. Sinking Pedal at Traffic Lights: Brake pedal continues to sink while held at a stop — a classic sign of failing internal seals
3. Increased Stopping Distance: Vehicle takes longer to stop than normal, even with firm pedal pressure
4. Brake Warning Light: Dashboard warning light illuminates with low fluid level and no visible external leaks
5. Fluid Leakage: Brake fluid seeping from the cylinder body or into the brake booster

Primary Applications:

As a Genuine OEM-quality part (AISIN), each brake master cylinder meets Toyota's stringent quality standards.
