Tools and Materials:
- Safety goggles
- Rubber gloves
- Wrench set
- Flat-head screwdriver
- Pliers
- New transmission fluid (recommended: DEXRON III)
- Clean rag
Instructions:
1. Safety Precautions:
- Ensure the vehicle is parked on level ground and the engine is turned off and has cooled down.
- Engage the parking brake to prevent the vehicle from rolling. Wear safety goggles and rubber gloves to protect yourself.
2. Locate the Clutch Master Cylinder Reservoir:
- Open the hood of your Mazda B2300. Locate the clutch master cylinder reservoir. It's usually a clear or translucent container with a black cap and is marked "CLUTCH FLUID" or "BRAKE FLUID."
3. Inspect Fluid Level:
- Check the fluid level in the reservoir. It should be between the "MIN" and "MAX" marks on the side of the reservoir.
4. Add Fluid (if needed):
- If the fluid level is low, add enough new transmission fluid (DEXRON III) to bring it between the "MIN" and "MAX" marks.
5. Bleed the Clutch System:
- Locate the clutch slave cylinder. It's usually attached to the transmission bell housing.
- Attach a clear hose to the bleeder valve on the clutch slave cylinder. Place the other end of the hose in a clear container.
- Have a helper hold down the clutch pedal while you loosen the bleeder valve. Allow any trapped air or fluid to escape.
- Close the bleeder valve while the clutch pedal is still depressed. Repeat this process several times until only fluid (with no air bubbles) comes out when the bleeder valve is opened.
6. Adjust the Clutch Pedal:
- Once you've bled the clutch system, it might be necessary to adjust the clutch pedal. Insert a flat-head screwdriver between the clutch pedal arm and the push rod.
- While pressing the clutch pedal down, turn the adjuster nut on the push rod until there's a slight gap (approximately 1/8-inch) between the clutch pedal arm and the push rod.
- Test the clutch pedal to ensure that has the proper amount of resistance when pressed.
7. Check for Leaks:
- Inspect the entire hydraulic system for any leaks, especially around the clutch master cylinder and slave cylinder. Tighten any loose connections if necessary.
8. Refill Reservoir (if needed):
- Check the fluid level in the clutch master cylinder reservoir again and top it up if necessary.
9. Test the Clutch:
- Start the engine and depress the clutch pedal. The transmission gears should shift smoothly without any grinding or resistance.
10. Test Drive:
- Take the vehicle for a test drive to ensure the clutch is working correctly. Drive in different gears and pay attention to how the clutch engages and disengages.
11. Check Adjustment:
- After a brief test drive, stop the vehicle and check the clutch pedal adjustment again. Make any necessary adjustments or refinements.
12. Regular Checks:
- Regularly check the clutch fluid level and the condition of the hydraulic components to ensure proper functionality.
NOTE: If you encounter difficulties or if the clutch still feels spongy or doesn't disengage properly, it's recommended to consult a professional mechanic or refer to the vehicle's service manual for specific instructions and recommendations.
