Here's why you can't just use a generic tool and what you'll need:
* It's probably NOT a simple C-clamp job: Attempting to compress the piston with a C-clamp could easily damage the piston seals, leading to brake fluid leaks and ultimately brake failure.
* You'll likely need a caliper piston compression tool: This specialized tool is designed to evenly compress the piston(s) while also protecting the seal. These tools either use a screw mechanism to push the piston in or a set of jaws that grip the piston evenly. This is the safest and recommended method. Auto parts stores (like AutoZone, Advance Auto Parts, etc.) or online retailers sell these tools. Make sure to get one that specifically fits the size and type of your Thunderbird's rear caliper pistons.
* A suitable container for brake fluid: As you compress the pistons, old brake fluid will be expelled. You'll need a container to catch this fluid. Brake fluid is corrosive, so wear gloves and eye protection.
* Clean rags or shop towels: You'll need these to clean up any spilled brake fluid.
* Possibly a brake line wrench: This might be needed to slightly loosen the brake line to relieve pressure on the system. However, this isn't always necessary if you're only working on one wheel at a time.
Steps (general, always refer to your repair manual for specific details):
1. Safety First: Wear safety glasses and gloves.
2. Loosen the caliper mounting bolts: This allows you to move the caliper out of the way to access the piston.
3. Position the compression tool: Carefully position the compression tool on the piston(s). Make sure the tool's jaws are properly seated and won't damage the caliper or piston.
4. Slowly compress the piston(s): Gently and evenly compress the pistons. Be aware that they might turn slightly as you press them in.
5. Reinstall the caliper: Once the pistons are compressed far enough to allow for pad replacement, reinstall the caliper.
6. Bleed the brakes: After replacing the pads and reinstalling the caliper, you *must* bleed the brakes to remove any air that may have entered the system. This is crucial for proper braking function.
Crucial Note: If you're not comfortable performing this task, it's strongly recommended to take your vehicle to a qualified mechanic. Incorrectly compressing the brake caliper piston can lead to serious brake problems and potential injury. A repair manual specific to your 1995 Ford Thunderbird will provide detailed instructions and diagrams.
