However, if you are determined to do this yourself, here's a general overview. This is NOT a complete guide and should not be used as the sole source of information. Consult a repair manual specific to your 1996 Ford Ranger's year, engine, and trim level for detailed instructions, diagrams, and torque specifications.
Safety First:
* Disconnect the negative battery cable before starting any work on the braking system.
* Wear safety glasses to protect your eyes from flying debris.
* Use jack stands to securely support the vehicle. Never work under a vehicle supported only by a jack.
* Have a helper if possible.
Rear Wheel Cylinder Replacement (More Common):
1. Preparation: Locate the wheel cylinder on the rear axle. You'll need to remove the wheel, tire, and brake drum. This often involves using a drum puller tool.
2. Bleeding the Brakes: Before disconnecting the lines, carefully bleed the brakes to release pressure in the system. This is crucial to prevent brake fluid spillage. Use a brake bleeder wrench and a clear tube to collect the fluid. You'll likely need to bleed the affected wheel and possibly the whole braking system afterwards.
3. Disconnecting the Lines: Carefully disconnect the brake lines from the wheel cylinder. Be prepared for some brake fluid to leak; have rags ready. You may need a flare nut wrench.
4. Removing the Wheel Cylinder: The cylinder is usually held in place by bolts or clips. Remove these carefully. Sometimes you can carefully pry it out, but avoid damaging the mounting points.
5. Installing the New Cylinder: Install the new wheel cylinder, ensuring it seats properly. Tighten the mounting bolts to the manufacturer's specified torque.
6. Connecting the Lines: Carefully connect the brake lines. Make sure the connections are tight to prevent leaks.
7. Bleeding the Brakes: Thoroughly bleed the brakes to remove any air from the system. This is a crucial step to ensure proper braking performance. Follow the correct bleeding order for your vehicle (often starting with the furthest wheel from the master cylinder).
8. Reassembly: Reinstall the brake drum and wheel.
9. Test: Carefully test the brakes several times in a safe location to ensure proper braking performance before driving.
Master Cylinder Replacement (Less Common, More Complex):
This is significantly more challenging and should only be attempted by experienced mechanics. It involves:
1. Bleeding the Brakes: Thoroughly bleed the entire braking system before disconnecting any lines.
2. Removing the Master Cylinder: This often involves disconnecting brake lines, removing bolts, and potentially disconnecting the brake booster.
3. Installing the New Master Cylinder: Ensure proper alignment and secure mounting.
4. Bleeding the Brakes: This is essential after installing a new master cylinder. Any air in the system will severely compromise braking performance.
5. Testing: Thoroughly test the brakes.
Important Notes:
* Brake fluid is corrosive and damaging to paint. Clean up any spills immediately.
* Always use the correct type of brake fluid specified in your owner's manual.
* Never reuse old brake lines or components. They might be weakened or damaged.
* If you're unsure about any step, consult a repair manual or professional mechanic. Improper brake repair is extremely dangerous.
This information is for general guidance only. Always consult a repair manual specific to your 1996 Ford Ranger before attempting any repair. Improper repair of brakes can lead to serious injury or death. If you are not comfortable performing this repair, take your vehicle to a qualified mechanic.
