Here's a step-by-step guide:
1. Locate the Bleeder Valves: The bleeder valves are located on each brake caliper (two per wheel, one for each piston). They are small screws typically on the top or side of the caliper.
2. Prepare the System: Ensure the brake fluid reservoir is topped off with fresh fluid. Keep an eye on the level throughout the process to avoid introducing air into the system.
3. Order of Bleeding: The standard order is:
* Rear Passenger Side: This is furthest from the master cylinder.
* Rear Driver Side:
* Front Passenger Side:
* Front Driver Side: This is closest to the master cylinder.
This order helps push air towards the master cylinder and out of the system.
4. Bleeding Procedure (per wheel):
* Attach the clear tube to the bleeder valve. Submerge the other end of the tube into the container of brake fluid.
* Have your helper pump the brake pedal slowly and firmly several times, then hold it down.
* While the pedal is held down, open the bleeder valve using the wrench. You should see brake fluid flowing through the tube. If bubbles appear, that's air being purged.
* Close the bleeder valve before your helper releases the brake pedal.
* Repeat steps 4-6 until no more bubbles appear in the fluid.
* Top off the brake fluid reservoir as needed.
5. Repeat for Each Wheel: Follow the order above, repeating steps 4-6 for each wheel.
6. Check the Fluid Level and Pedal Firmness: Once all wheels are bled, check the brake fluid level in the reservoir and top it off if necessary. Test the brake pedal. It should feel firm and responsive. If the pedal feels soft or spongy, you may need to repeat the bleeding process.
7. Test Drive (Caution): After bleeding, perform a very cautious test drive. Be prepared to stop slowly, and make sure the brakes feel firm and responsive before driving normally.
Specific Considerations for the 1987 Fiero:
* Accessibility: The Fiero's wheel wells can be relatively tight, so you might need to use a flexible wrench or extension to reach some of the bleeder valves.
* Brake System Type: Familiarize yourself with your Fiero's brake system. Some models may have different caliper designs. A shop manual specific to your year and model will be very helpful.
* Power Brakes: If your Fiero has power brakes, make sure the engine is running during the bleeding process to assist the power booster.
If you are uncomfortable performing this task yourself, it's best to take your Fiero to a qualified mechanic. Improperly bled brakes can be extremely dangerous. A shop manual specific to your vehicle will provide diagrams and crucial details to ensure you complete the job correctly.
