1. Damaged Brake Line: There is likely a ruptured or damaged brake line near the right rear wheel. Brake lines are responsible for carrying brake fluid from the master cylinder to the wheel cylinders or calipers. A leak in the line can cause a significant drop in brake fluid levels and compromise the braking capabilities.
2. Faulty Wheel Cylinder/Caliper: The right rear wheel cylinder or caliper, which are essential components that apply pressure to the brake pads to stop the wheel, could be malfunctioning. A worn-out seal or piston within these components can cause brake fluid to leak.
3. Damaged Brake Hoses: Brake hoses are flexible lines connecting the rigid brake lines to the wheel cylinders or calipers. These hoses can deteriorate or crack over time, leading to a brake fluid leak near the right rear wheel.
4. Improper Installation or Maintenance: If recent brake-related work has been done on your Tahoe, such as replacing the brake pads or fluid, it's possible that incorrect installation or loose components may have caused the leak.
5. Rust and Corrosion: Older vehicles, like your 1996 Tahoe, may experience rust and corrosion around brake lines and components. This corrosion weakens the metal and makes it more susceptible to cracking or leaking.
6. Master Cylinder Issues: While less likely, a problem with the master cylinder itself, which is the reservoir and control center for brake fluid, could lead to a leak near the right rear wheel if the fluid is not adequately distributed.
7. ABS System Fault: If your Tahoe is equipped with an anti-lock braking system (ABS), a malfunction within the ABS module or related lines could cause a brake fluid leak near the right rear wheel.
It's crucial to address a brake fluid leak promptly as it affects your vehicle's ability to brake safely and effectively. Avoid driving the vehicle until the source of the leak is identified and repaired by a qualified mechanic or automotive technician.
