Here's a general overview. This is NOT a complete, step-by-step guide, as variations exist depending on the specific line being replaced. Consult a repair manual specific to your 1993 Ford Tempo for detailed instructions, diagrams, and torque specifications. A Haynes or Chilton manual would be helpful.
Tools You'll Need:
* Wrench set (metric): Various sizes will be needed to remove brake line fittings and related components.
* Line flaring tool: Essential for properly flaring the ends of the new brake lines for a leak-free connection.
* Brake line tubing cutter: For clean cuts on the new brake lines.
* Tube bender: To avoid kinks in the new lines (highly recommended).
* Flare nut wrench: These prevent rounding off the nuts on the brake lines.
* Sockets and ratchet: For removing and installing various fasteners.
* New brake lines: Get the correct length and type from an auto parts store. Specify your Tempo's year and model.
* Brake fluid: DOT 3 or DOT 4, as specified in your owner's manual.
* Clean rags: For cleaning up brake fluid spills.
* Safety glasses: To protect your eyes from flying debris and brake fluid.
* Gloves: To protect your hands from brake fluid and potential cuts.
* Jack and jack stands: To safely lift and support the vehicle.
* Wheel chocks: For added safety.
General Steps (Highly Simplified and NOT a complete guide):
1. Safety First: Disconnect the negative battery terminal. Use jack stands to securely lift the vehicle and properly support it. Engage the parking brake. Place wheel chocks on the wheels that are still on the ground.
2. Locate the Damaged Line: Identify the section of brake line that needs replacing.
3. Bleed the Brakes: Before disconnecting any brake lines, bleed the brakes to release pressure in the system. This prevents fluid spraying when you disconnect lines.
4. Disconnect the Old Line: Carefully loosen and remove the fittings at both ends of the damaged brake line. Use the correct wrenches to prevent damage. Be prepared for some brake fluid to escape.
5. Measure and Cut the New Line: Carefully measure the length needed for the new brake line, ensuring sufficient slack for movement and avoiding tight bends. Use the tubing cutter to make a clean, square cut.
6. Flare the New Line: Use the flaring tool to create the correct flare on the ends of the new brake line. This is crucial for a proper seal.
7. Bend the New Line (if necessary): Carefully bend the new line to match the route of the old line, using a tube bender to avoid sharp bends or kinks that could restrict flow or weaken the line.
8. Connect the New Line: Carefully connect the new brake line to the fittings at both ends, ensuring a snug and leak-free connection. Tighten the fittings to the manufacturer's specified torque (refer to your repair manual).
9. Reconnect the Brake Lines: Reattach the remaining brake lines and components.
10. Bleed the Brakes: After installing the new brake lines, carefully bleed the brakes at each wheel to remove any air that may have entered the system. This is crucial for proper braking performance. Follow the bleeding procedure outlined in your repair manual.
11. Test the Brakes: After bleeding the brakes, test them thoroughly in a safe, controlled environment. Make sure the brakes work correctly before driving the vehicle.
Again, this is a highly simplified overview. Refer to a repair manual specific to your 1993 Ford Tempo for detailed instructions and safety precautions. Improper brake repair can lead to serious injury or death. If you have any doubts about your ability to perform this repair safely, take your vehicle to a qualified mechanic.
