Tools you'll likely need:
* Jack and jack stands (essential for safety)
* Wheel chocks
* Wrench(es) – various sizes (check your manual for specific sizes)
* Socket set and ratchet
* Screwdrivers (possibly Phillips and flathead)
* C-clamp or brake spring tool (highly recommended)
* Hammer (possibly)
* Penetrating oil (like PB Blaster)
* Brake cleaner
* Gloves
* Safety glasses
Procedure (for drum brakes):
1. Safety First: Park on a level surface, engage the parking brake, chock the front wheels, and raise the rear of the vehicle securely using a jack and jack stands. Never work under a vehicle supported only by a jack.
2. Remove the Wheel: Remove the wheel lug nuts and then the wheel itself.
3. Remove the Drum: You might find the drum is stuck. If so, use a rubber mallet (gently!) to tap around the circumference of the drum to break it loose. Sometimes penetrating oil applied to the drum's mounting flange helps. Once loose, carefully pull the drum off the wheel studs.
4. Inspect the Brake Shoes: Now you should see the brake shoes, wheel cylinders, and other components. Note their position and take pictures if it helps you remember the reassembly process.
5. Remove the Brake Shoes: This is the trickiest part. There are usually several springs holding the shoes in place. Use the C-clamp or brake spring tool to carefully compress and remove the springs. Be very careful not to damage the springs or shoes. The springs are under tension and can snap back unexpectedly.
6. Remove the Wheel Cylinders: Once the springs are off, the brake shoes should be removable. You'll then need to remove the wheel cylinders. These usually have a retaining clip or bolt holding them in place. Some penetrating oil might help loosen them. Be prepared for some brake fluid to leak; have rags handy.
7. Inspect and Replace Components: Carefully inspect all components (shoes, cylinders, springs, drums) for wear and tear. Replace any worn or damaged parts. If the wheel cylinders are leaking, they *must* be replaced.
8. Reassembly: Reassembly is the reverse of disassembly. Be sure to properly install the springs using the spring tool to avoid damaging them. Make sure the brake shoes are correctly adjusted. This often involves a small star wheel adjuster.
9. Reinstall the Drum: Carefully slide the drum back onto the wheel studs.
10. Reinstall the Wheel: Replace the wheel and tighten the lug nuts to the manufacturer's specified torque.
11. Lower the Vehicle: Carefully lower the vehicle using the jack.
12. Test the Brakes: Before driving, carefully test the brakes. If the brake pedal feels spongy or the brakes are not working correctly, you may need to bleed the brakes to remove air that may have entered the system during the repair. If you are unsure about bleeding the brakes, consult a professional mechanic.
If your LeSabre has disc brakes in the rear (less likely, but possible), the process is different and considerably more complex. This involves removing calipers, pads, and potentially rotors. Again, consult a repair manual for your specific vehicle.
