Here's a breakdown:
Tools you'll *likely* need:
* Socket set (metric): Various sizes to remove lug nuts, caliper bolts (if the rear brakes are self-adjusting, you may only need to remove the caliper and shoes), and possibly other fasteners.
* Wrench set (metric): For those same fasteners; sometimes a wrench provides better access than a socket.
* Jack and jack stands: Absolutely essential for safety. Never work under a car supported only by a jack.
* Wheel chocks: To prevent the car from rolling.
* Screwdrivers (Phillips and flathead): Possibly for various clips or fasteners.
* Pliers: Needle-nose pliers are helpful for manipulating brake springs and small parts.
* Brake shoe spreader: While not strictly "specialized," a brake shoe spreader makes it much easier to compress the springs and reinstall the shoes. You *can* probably do it without one, but it's significantly harder and more prone to causing damage.
* C-clamp (optional but helpful): Can be used in place of a brake spring compressor in a pinch.
* Wire brush: To clean brake drum surfaces.
* Grease: To lubricate the pins and slides (if applicable).
* Owner's manual: Highly recommended to check for any specific steps or torque specifications.
Why it's difficult without some tools:
The main challenge lies in compressing the return springs that hold the brake shoes against the drum. These springs are under tension, and attempting to manipulate them without proper tools can be dangerous and lead to injury or broken parts. A brake spring compressor, or a good substitute like a C-clamp, is strongly recommended.
In short: While technically feasible, changing rear brake shoes on a 1995 LeSabre without *at least* a brake spring compressor or equivalent, and a good set of general automotive tools, is strongly discouraged. It's much safer, easier, and less likely to result in damage to use the appropriate tools. If you're uncomfortable with automotive repair, consider having a professional mechanic perform the service.
