However, if you're determined to try it yourself (at your own risk), here's a general outline of the process. Remember, this is a simplification and specific procedures may vary slightly. Consult a repair manual specific to your 2002 Chevrolet Blazer for precise instructions and safety precautions.
Steps (Generally):
1. Engage the Parking Brake: Ensure the parking brake is fully engaged.
2. Safety First: Secure the vehicle on a level surface. Use jack stands, never rely solely on a jack. Chock the front wheels.
3. Remove Rear Wheels: Loosen the lug nuts before jacking up the vehicle, then remove the wheels.
4. Inspect the Brake System: Examine the brake drums (which are part of the rotors on this system) for wear, damage, or rust. Pay attention to the brake shoes and the automatic adjuster mechanism within the drum.
5. Assess the Parking Brake Shoes: The parking brake shoes are inside the drum and are part of the rear brake assembly. They often have an automatic adjuster that self-adjusts with regular braking.
6. Possible Adjustment (Usually Not Necessary and Often Inaccessible Without Specialized Tools): In some cases, there might be a small star wheel adjuster accessible through a hole in the backplate. This is used to manually adjust the parking brake shoes. This is *rare* on this system; it's *much more likely* that the adjustment is handled automatically and not user accessible. Trying to force an adjustment where it's not meant to be adjusted will likely damage the system.
7. Check the Cables: Inspect the parking brake cables for damage, fraying, or corrosion. Replacing frayed or damaged cables is usually the first step. This may need to be done even if the shoes are properly adjusted. There might be some slack adjustment *at the cable itself*, but it's typically only a small amount.
8. Reassemble: Once you've inspected everything, reinstall the wheels, lower the vehicle, and test the parking brake.
Important Considerations:
* Automatic Adjusters: Most integrated parking brakes of this era rely on automatic adjusters. If the parking brake is weak, it's far more likely a problem with the cable, the shoes themselves (worn), or the automatic adjuster mechanism (stuck or broken) than needing manual adjustment.
* Repair Manual: Get a repair manual for your specific year and model Blazer. It will have detailed diagrams, torque specifications, and safety procedures. This is *crucial* for this type of repair.
* Brake Fluid: If you're working with the rear brake system, you might accidentally spill brake fluid. Keep it away from your paint and skin, and wear appropriate safety glasses.
* Professional Help: This is a potentially complex brake repair. If you're uncomfortable with any of the steps, take it to a qualified mechanic. Improper brake repairs can be dangerous.
