Tools You'll Need:
* Jack and jack stands
* Lug wrench
* Wheel chocks
* Socket wrench set (metric) – likely need 13mm, 15mm, and possibly others
* Wrenches (metric) – potentially needed for caliper bolts
* C-clamp or brake caliper compression tool
* Brake cleaner
* New brake pads
* New brake shoes (if drum brakes, less common on 97 Suburban)
* Possibly new hardware (clips, springs, etc.) – always a good idea to replace these
* Wire brush or sandpaper (for cleaning surfaces)
* Gloves
* Penetrating lubricant (like PB Blaster)
Procedure (assuming rear disc brakes; confirm your Suburban's brake type):
1. Safety First: Park on a level surface, engage the parking brake, and chock the front wheels. Use jack stands under the frame near the rear axle after lifting the vehicle with the jack. Never work under a vehicle supported only by a jack.
2. Remove the Wheel: Remove the lug nuts and carefully remove the wheel.
3. Inspect the Brakes: Examine the brake pads for wear. Measure the pad thickness – if they're below the minimum thickness specified in your repair manual, they need replacing. Also check the brake caliper for damage or leaks.
4. Compress the Caliper Piston: Use a C-clamp or brake caliper compression tool to push the piston back into the caliper. This creates space for the new, thicker brake pads. You may need to turn the piston while compressing it. Be careful not to damage the piston seal.
5. Remove the Brake Pads: Usually, you'll need to remove a pin or bolt holding the brake pad retaining clip. Once removed, the pads should slide out.
6. Clean the Caliper and Mounting Brackets: Use a wire brush or sandpaper to clean any rust or debris from the caliper brackets and the caliper piston surface. Clean everything thoroughly with brake cleaner.
7. Install New Brake Pads: Install the new brake pads, ensuring they slide smoothly in their slots. Reinstall the retaining clip and pin.
8. Reinstall the Wheel: Put the wheel back on, and tighten the lug nuts snugly. Lower the vehicle to the ground.
9. Torque Lug Nuts: Torque the lug nuts to the manufacturer's specified torque (found in your repair manual).
10. Pump the Brakes: With the vehicle on the ground, pump the brake pedal several times to ensure the pads are properly seated.
11. Test Drive: Test drive the vehicle to verify that the brakes are working correctly.
If you have rear drum brakes (less likely on a 1997 Suburban):
The process is more involved. You'll need to remove the backing plate, adjust the wheel cylinders, and install new shoes and hardware. This typically requires specialized tools and more expertise. A repair manual is crucial here.
Important Considerations:
* Bleeding the Brakes: While not always necessary after a pad replacement, it's good practice to bleed the brakes after a brake job. This removes any air that may have gotten into the system.
* Repair Manual: A repair manual specific to your 1997 Chevy Suburban is highly recommended. It will provide detailed instructions, torque specifications, and diagrams.
* Professional Help: If you're not comfortable working on brakes, it's best to have a qualified mechanic perform the repair. Brake failure can have serious consequences.
This is a simplified overview. Always refer to your vehicle's service manual for the correct procedure and safety precautions. Improper brake repair can be dangerous.
