Here's a general guide. Specific steps might vary slightly depending on your exact Protege model and trim level. Consult your owner's manual for specific instructions and torque specifications. This is a general guide and should not replace professional advice.
Tools You'll Need:
* Jack and jack stands
* Wheel chocks
* Socket wrench set (metric) – you'll likely need 12mm, 14mm, and possibly others
* Wrench set (metric)
* C-clamp (optional, but helpful)
* Pliers or brake caliper piston compressor tool
* Brake cleaner
* New front brake pads
* Gloves
* Rags or shop towels
Steps:
1. Safety First: Engage the parking brake, chock the rear wheels, and jack up the front of the vehicle. Securely place it on jack stands. Never work under a vehicle supported only by a jack.
2. Remove the Wheel: Remove the lug nuts from the wheel using the appropriate socket. Then, carefully remove the wheel and set it aside.
3. Expose the Caliper: You should now see the brake caliper assembly.
4. Remove the Caliper: There are usually two bolts securing the caliper to the caliper bracket. Use the correct socket wrench to carefully remove these bolts. Once removed, carefully support the caliper. You may want to hang it from something nearby using some wire or string to keep it out of the way and prevent damage to the brake hose. Do not let the caliper hang by the brake hose.
5. Compress the Piston: Use a C-clamp or a dedicated brake caliper piston compressor tool to push the brake caliper piston back into the caliper. This creates the space needed for the new, thicker brake pads. You may need to turn the piston slowly as you compress it, it will usually rotate. Be careful not to damage the piston seal or the boot.
6. Remove Old Pads: The old brake pads should now be easily removed. They are typically held in place by a spring clip or by friction. Gently pry them out if necessary.
7. Install New Pads: Install the new brake pads into the caliper bracket. Make sure they slide in smoothly and are properly seated.
8. Reinstall the Caliper: Carefully reinstall the caliper onto the bracket, ensuring the bolts are tightened to the manufacturer's specified torque.
9. Reinstall the Wheel: Carefully replace the wheel and tighten the lug nuts in a star pattern (opposite nuts first, then the others).
10. Lower the Vehicle: Carefully lower the vehicle from the jack stands.
11. Check and Test: Tighten the lug nuts again after lowering the vehicle. Pump the brake pedal several times to ensure the brakes are working correctly. Then, test the brakes gently in a safe, controlled environment, such as an empty parking lot. Be prepared for an initial soft pedal feel as the pads bed in.
Important Considerations:
* Brake Fluid: While not directly involved in pad replacement, regularly check your brake fluid level. If the fluid is low, it may indicate a leak, which needs professional attention.
* Rotor Condition: While replacing the pads, inspect the brake rotors for wear and scoring. If they are excessively worn or damaged, they will need to be replaced or resurfaced by a professional.
* Professional Help: If you are uncomfortable performing this repair yourself, it's best to take your vehicle to a qualified mechanic. Brake repair is crucial for safety.
This guide provides a general overview. Always refer to a repair manual specific to your 1997 Mazda Protege for detailed instructions and torque specifications. Improper brake repair can be dangerous. If you're uncertain about any step, seek professional assistance.
