Tools You'll Need:
* Brake fluid: Use DOT 3 brake fluid (check your owner's manual). *Never* mix different types of brake fluid.
* Bleeding wrench: A 8mm or 10mm wrench (check the size of your bleeder valve) or a brake bleeder tool.
* Clear tubing: About 3 feet long, to fit over the bleeder valve.
* Jar or container: To catch the old brake fluid.
* Socket wrench: Probably a 10mm and possibly a 13mm to possibly remove the caliper bolts.
* Gloves: Brake fluid is corrosive.
* Shop rags: To clean up spills.
* Helper: Crucial for this procedure.
Procedure:
1. Safety First: Engage the parking brake firmly. Make sure the car is on a level surface.
2. Locate Bleeder Valves: The bleeder valves are located on top of each brake caliper. The rear calipers might require removing the caliper bolts to get a better angle. Front calipers typically do not require removing them.
3. Fill the Master Cylinder Reservoir: Check the brake fluid level in the master cylinder reservoir. Top it off with fresh DOT 3 brake fluid. Keep an eye on the fluid level throughout the bleeding process, and top it off as needed to prevent air from entering the system.
4. Bleeding Sequence: The standard bleeding sequence is: Right Rear, Left Rear, Right Front, Left Front. This ensures that the farthest points from the master cylinder are bled first. *Some sources may suggest a different order. Refer to your owner's manual for their recommendation.*
5. Bleeding Process (for each wheel):
* Have your helper pump the brake pedal several times and then hold it down.
* Open the bleeder valve slowly using the wrench (only slightly - a half to three-quarter turn).
* You should see brake fluid flow through the clear tubing into the jar.
* Keep the brake pedal firmly depressed by your helper.
* Once the fluid flow becomes steady and free of bubbles, close the bleeder valve.
* Have your helper release the brake pedal.
* Repeat this process several times for each wheel until the fluid runs clear and free of air bubbles.
6. Check Fluid Level: After bleeding each wheel, check and refill the master cylinder reservoir as needed.
7. Test the Brakes: After bleeding all four wheels, carefully test the brakes in a safe, open area, away from traffic. If the pedal feels spongy or the brakes are weak, you may need to bleed the brakes again.
8. Clean Up: Clean up any spilled brake fluid immediately.
Important Considerations:
* Air in the System: If you can't get all the air out, you may have a more serious problem, like a leak in a brake line. You may want to consult a professional mechanic if this is the case.
* Power Brakes: If your Celebrity has power brakes, the brake pedal will require more force to pump.
* ABS System: If your vehicle has Anti-lock Braking System (ABS), bleeding the brakes is significantly more complex and often requires specialized equipment. In that instance, take it to a mechanic. Most 1989 Chevy Celebrities did *not* have ABS, but it's worth checking.
This is a general guide. Always consult your owner's manual for specific instructions and safety precautions relevant to your 1989 Chevy Celebrity. If you are unsure about any part of this process, it's best to seek professional help from a qualified mechanic. Brake failure can be extremely dangerous.
