Tools You'll Need:
* Clutch bleeding kit: This typically includes a clear hose, a container to catch the fluid, and a wrench that fits the bleeder valve.
* Wrench: To access and loosen the bleeder valve on the slave cylinder. Likely a 10mm or 8mm, but double-check.
* Brake fluid: DOT 3 or DOT 4 brake fluid (check your owner's manual for the specific recommendation). Never use anything else.
* Clean rags or shop towels: To clean up spills.
* Funnel: To easily add brake fluid to the master cylinder reservoir.
* Socket wrench might be helpful to reach the bleeder screw on the slave cylinder. An extension or universal joint could be necessary depending on the access.
Procedure:
1. Locate the Clutch Master Cylinder: This is typically found under the dash, near the brake master cylinder. It's a smaller cylinder.
2. Locate the Clutch Slave Cylinder: This is located on the transmission. This is where the bleeder valve is located. Accessing it might be tricky; you may need to remove some parts or use a small wrench and possibly an extension.
3. Check the Master Cylinder Reservoir: Ensure the master cylinder reservoir is topped off with the correct brake fluid.
4. Attach the Bleeding Kit: Attach one end of the clear hose to the bleeder valve on the slave cylinder. Submerge the other end of the hose into the container filled with brake fluid. This prevents air from entering the system.
5. Have Your Helper Pump: Have your helper slowly and repeatedly pump the clutch pedal. They should hold the pedal down after the last pump.
6. Open the Bleeder Valve: Carefully open the bleeder valve with your wrench. You should see fluid flowing through the hose, and possibly some bubbles.
7. Close the Bleeder Valve: Once the flow of fluid slows and/or only clear fluid comes out, have your helper release the clutch pedal. Then close the bleeder valve tightly.
8. Repeat: Repeat steps 5-7 several times until no more air bubbles are visible in the hose. This might take several cycles.
9. Top Off the Master Cylinder: Top off the master cylinder reservoir as needed.
10. Check the Clutch: Have your helper test the clutch pedal. It should feel firm and have a good response. If it feels spongy or weak, repeat the bleeding process.
11. Check for Leaks: Inspect all connections and the bleeder valve for leaks.
Important Considerations:
* Air in the system: If you struggle to get the air out, try gravity bleeding. This involves opening the bleeder valve and letting the fluid slowly drain, possibly overnight.
* Difficult access: Accessing the slave cylinder bleeder valve can be challenging on a Fiero. You might need to consult a repair manual or online forums for specific location and access tips.
* Fluid Type: Use the correct DOT-rated brake fluid. Using the wrong fluid can damage your clutch system.
* Professional Help: If you're uncomfortable with this procedure or are not mechanically inclined, it's best to take your Fiero to a qualified mechanic. This is especially true if you have problems accessing the slave cylinder bleeder.
Remember safety first! Always wear safety glasses to protect your eyes from splashing fluid. Brake fluid can damage paint, so be careful. If you're unsure about any part of this process, it's always best to consult a professional. A repair manual specific to your 1987 Pontiac Fiero will be invaluable.
