Possible Causes:
* Cable Adjustment: The most common problem is simply that the emergency brake cables are loose or need adjustment. Over time, they can stretch.
* Cable Damage: The cables themselves might be frayed, broken, or corroded. This often happens near the lever or where the cables connect to the rear brakes.
* Brake Shoes/Pads: The rear brake shoes (drum brakes) or pads (disc brakes – less likely on an Alero) might be worn down or contaminated with grease or oil, preventing them from gripping the rotors or drums effectively. Even if the shoes/pads have some material left, they might be glazed and ineffective.
* Rear Brake System Issues: Problems in the rear brake system itself (like a seized caliper, a leaking wheel cylinder, or low brake fluid) can indirectly affect the e-brake's performance.
* Parking Brake Lever/Mechanism: The lever inside the car could be broken or malfunctioning. The internal mechanism that connects the lever to the cables could also be faulty.
* Frozen Components: In very cold climates, components can freeze and prevent the e-brake from working.
What to Do:
1. Safety First: Do NOT drive the car until the e-brake is repaired. It's a critical safety feature.
2. Check the Obvious: Start by trying to adjust the e-brake cable. Most Aleros have an adjustment mechanism near the rear of the car where the cables connect to the brake system. Consult your owner's manual for the exact location and adjustment procedure. This is usually a simple turn of a nut or star adjuster.
3. Inspect the Cables: Carefully examine the entire length of the emergency brake cables for any visible damage, fraying, or corrosion.
4. Check Brake Fluid Level: Ensure your brake fluid is at the correct level in the master cylinder reservoir. Low fluid could indicate a leak in the rear brake system.
5. Professional Inspection: If you're not comfortable working on your car's brakes, take it to a qualified mechanic. They have the tools and expertise to diagnose and repair the problem accurately. Attempting brake repairs without the proper knowledge is dangerous.
6. Owner's Manual: Refer to your owner's manual for specific diagrams and instructions relating to the emergency brake system on your 2002 Oldsmobile Alero.
Important Note: Brake systems are complex. If you're not mechanically inclined, it is strongly recommended that you have a professional assess and repair the issue. Driving a car with a faulty e-brake is dangerous.
