What you'll need:
* New Clutch Fluid: DOT 3 or DOT 4 brake fluid (check your owner's manual to be sure). Use only new fluid; old fluid can contain moisture and damage the system.
* Bleeding wrench: A wrench that fits the bleeder valve on the slave cylinder (usually 8mm or 10mm).
* Clear tubing: Long enough to reach a container.
* Container: To catch the old fluid.
* Assistant: To pump the clutch pedal.
* Jack and Jack Stands (optional but recommended): For easier access to the bleeder valve, especially if it’s difficult to reach.
* Gloves: Brake fluid is corrosive.
* Rags or Shop Towels: To clean up any spills.
Procedure:
1. Locate the Bleeder Valve: The bleeder valve is located on the slave cylinder, which is attached to the transmission bell housing. It's usually a small, hex-shaped fitting. You might need a flashlight and some maneuvering to find it. The location can be tricky on some Berettas. A shop manual would be very helpful here.
2. Prepare the System: Have your assistant sit in the driver's seat. Top off the master cylinder reservoir with fresh brake fluid. Keep an eye on this level throughout the process and top it off as needed, as it will drop during bleeding.
3. Attach the Tubing: Attach one end of the clear tubing to the bleeder valve. Submerge the other end into the container.
4. Bleeding Process: Your assistant will slowly and steadily pump the clutch pedal several times. Important: They should *not* hold the pedal down. After each pump, they should release the pedal completely.
5. Open the Bleeder Valve: While your assistant is pumping the clutch pedal, slightly crack open the bleeder valve with the wrench. You should see fluid flowing through the tube into the container. Close the valve when your assistant releases the pedal.
6. Repeat: Repeat steps 4 and 5 several times until the fluid running through the tube is clean and free of air bubbles. Pay close attention to the fluid color; you're looking for a consistent, clear color.
7. Check Fluid Level: Make sure the master cylinder reservoir is still topped off with fresh brake fluid.
8. Re-check Clutch Pedal: After bleeding is complete, check the clutch pedal for proper feel. It should be firm and not spongy.
9. Final Check: After several clutch actuations, check for leaks around the master and slave cylinders.
Troubleshooting:
* Air Bubbles persisting: If you are having trouble getting rid of air bubbles, try gravity bleeding. This involves leaving the bleeder valve slightly open for an extended period while the clutch master cylinder reservoir is full. Gravity will help draw out air bubbles.
* Clutch pedal still spongy: If the clutch pedal remains spongy after bleeding, you might have a problem with the master cylinder, slave cylinder, or even a leak somewhere in the hydraulic line. You may need professional help if this persists.
Important Considerations:
* Safety: Always wear safety glasses and gloves when working with brake fluid.
* Shop Manual: A shop manual specific to your 1992 Chevy Beretta V6 will be invaluable for this procedure. It will provide detailed diagrams and instructions.
This process can be challenging. If you're not comfortable doing this yourself, take it to a qualified mechanic. A poorly bled clutch can lead to clutch failure.
