You will need to access and manually release the brake mechanism itself. This usually involves:
1. Locating the Emergency Brake Cables: These typically run from under the center console or near the transmission hump towards the rear wheels. You may need to remove some interior trim pieces to find them. A repair manual specific to your year and model Blazer is highly recommended for this step.
2. Identifying the Brake Mechanism: The cable connects to a lever or other mechanism at each rear wheel. This is usually located near the parking brake shoes or caliper (depending on whether you have drum or disc brakes in the rear).
3. Manually Releasing the Brakes: This is the tricky part and will depend on your vehicle's specific brake setup. It often involves using tools to carefully manipulate the lever or mechanism to release the brakes. This may require significant mechanical skill and knowledge. Improperly attempting this can cause damage to your brake system.
Strongly Recommended Steps:
* Consult a Repair Manual: A repair manual specific to your 1998 Chevy Blazer is crucial. It will provide detailed diagrams and instructions for accessing and releasing the emergency brake mechanism.
* Seek Professional Help: This is not a simple task for most individuals. The risk of further damage to your brake system and potential injury outweighs trying to do this yourself if you lack mechanical experience. A qualified mechanic will have the knowledge and tools to safely release the brake and repair or replace the broken cable.
* Towing: If you cannot safely access and release the brake, towing the vehicle is the safest option.
WARNING: Attempting this repair without proper knowledge and tools can lead to serious damage to your vehicle's brake system and possibly personal injury. Safety should be your top priority.
