If your parking brake isn't working correctly (engaging properly or releasing properly), the problem is likely one of the following and requires professional attention:
* Brake System Malfunction: The most common cause. This could involve a problem with the electronic control module, wiring, rear brake calipers, or the brake fluid level/condition.
* Low Brake Fluid: Check your brake fluid level in the master cylinder reservoir. Low fluid could indicate a leak somewhere in the braking system.
* Faulty Parking Brake Switch: This switch might be malfunctioning, preventing the system from engaging correctly.
* Calipers themselves: The internal mechanism of the rear calipers could be seized or failing.
In short: You cannot adjust it yourself. Take your Corvette to a qualified mechanic or dealership service center for diagnosis and repair. Attempting to adjust it yourself could lead to further damage and potentially costly repairs. They have the diagnostic tools and expertise to pinpoint the problem and fix it safely.
