Here's a general procedure. Specifics might vary slightly depending on the exact trim level and any modifications. Always consult a repair manual specific to your 1998 Mazda Protege for precise details and diagrams.
Tools You'll Likely Need:
* Jack and jack stands
* Wheel chocks
* Socket wrench set (metric)
* Wrenches (metric)
* Pliers (possibly need-nose pliers)
* C-clamp (optional, but helpful)
* Brake cleaner
* Gloves
Procedure:
1. Safety First: Securely park the Protege on a level surface, engage the parking brake, and chock the rear wheels. Jack up the front of the vehicle and securely support it with jack stands.
2. Remove the Wheel: Remove the wheel using the appropriate lug wrench.
3. Expose the Caliper: You should now see the brake caliper assembly.
4. Locate the Caliper Bolts: There are usually two bolts holding the caliper to the caliper bracket. These are typically located on the back of the caliper. Locate and carefully loosen these bolts using the appropriate socket wrench. Do not completely remove them yet.
5. Compress the Piston: With the caliper bolts slightly loosened, you'll need to compress the brake caliper piston. This is necessary to create enough space to remove the old brake pads. You can use a C-clamp to carefully compress the piston. Important: Be careful not to damage the piston seal. Some pistons require turning as you compress them. Be aware that brake fluid will be expelled. Have a rag ready to absorb the fluid, and ensure the master cylinder reservoir has enough space (it's better to check the fluid level *before* starting this step).
6. Remove the Caliper: Once the piston is compressed sufficiently, carefully remove the caliper bolts completely and gently lift the caliper off the rotor. You might need to support the caliper with a bungee cord or wire to keep it hanging from the brake line.
7. Remove the Brake Pads: The brake pads should now be visible. They are usually held in place by spring clips or pins. Carefully remove these clips or pins and pull out the old brake pads. Clean the caliper bracket, and compare your new brake pads to the old ones; make sure the new ones fit appropriately.
8. Install New Brake Pads: Install the new brake pads into the caliper bracket, ensuring they are seated correctly.
9. Reinstall the Caliper: Carefully reinstall the caliper onto the rotor. Make sure the caliper slides smoothly over the brake pads. Tighten the caliper bolts to the manufacturer's specified torque.
10. Reinstall the Wheel: Install the wheel and tighten the lug nuts to the manufacturer's specified torque. Do this in a star pattern to ensure even tightening.
11. Lower the Vehicle: Carefully lower the vehicle to the ground.
12. Pump the Brakes: Pump the brake pedal several times to ensure the brakes are working correctly.
13. Test Drive: Test drive the vehicle to check the brakes. If you notice any unusual noises, vibrations, or spongy brake pedal feel, recheck your work.
Important Notes:
* Bleeding Brakes: In some cases, after compressing the caliper piston and working on the brakes, it might be necessary to bleed the brakes to remove any air that might have entered the system. This usually requires a second person and a bleeding kit. Consult your repair manual for instructions.
* Rotor Inspection: While the wheel is off, inspect the rotor for wear and tear. If it's excessively worn or scored, it may need to be replaced or resurfaced.
* Professional Help: If you're not comfortable performing this repair yourself, consult a qualified mechanic. Brake repair is crucial for safety.
This is a general guide. Always refer to your vehicle's repair manual for detailed instructions and torque specifications. Failure to follow proper procedures can lead to brake failure and serious injury.
