Improper adjustment can lead to problems. If your E-brake isn't working properly, it's best to have a mechanic diagnose the issue. However, if you're comfortable working on your car, you can try these steps, keeping in mind that this is not a simple task and requires some mechanical skill:
1. Identify the type of rear brakes: The 1999 Chevy Prizm likely has either drum brakes or disc brakes in the rear. This will determine how you approach the adjustment. Check your owner's manual or look at the rear wheels to determine the type.
2. Drum brakes (less common, but possible on a 99 Prizm): If you have drum brakes, there is usually an adjuster wheel or star wheel located on the back of the backing plate (the metal plate behind the drum). You will need to remove the wheel and possibly the drum to access it. Turning this wheel will tighten the brake shoes. This requires carefully turning it small increments and testing frequently to avoid over tightening. Over tightening can lead to dragging brakes and damage.
3. Disc brakes (more likely on a 99 Prizm): With disc brakes, the adjustment is usually done at the caliper. There's no external adjustment. Instead, the issue is likely with the cable tension or possibly a problem within the caliper mechanism. Adjusting this requires specialized tools and is best left to a mechanic.
4. Cable adjustment (potential, but less common solution): If there's slack in the cable itself, there might be an adjuster near the lever. But this is rare on a 99 Prizm and is not the typical way to address a weak e-brake.
In short: Don't attempt to "tighten" the e-brake directly. A weak e-brake on a 99 Prizm points to a more serious issue within the rear brake system. You should take it to a mechanic for proper diagnosis and repair. Attempting to adjust the brakes incorrectly could cause more damage or lead to unsafe driving conditions.
