Tools and Materials Needed:
- Empty Brake fluid Container
- Wrench Set (metric and SAE)
- Pliers
- Siphon or turkey baster
- Brake Cleaner
- Rags
- Small funnel
- New brake fluid (DOT3)
Procedure:
1. Safety First:
Ensure the vehicle is parked in a safe area, the emergency brake is engaged, and the engine is off.
2. Locate Master Cylinder:
In the engine bay, find the master cylinder. On a 1993 Honda Accord, it is usually located near the firewall on the driver's side.
3. Remove Reservoir Cap:
Gently remove the cap from the master cylinder. Be cautious, as brake fluid can damage paint.
4. Drain Old Fluid:
Use a siphon or turkey baster to remove as much old brake fluid from the master cylinder reservoir as possible.
5. Disconnect Brake Lines:
Locate the brake lines connected to the master cylinder. Use a wrench to loosen and disconnect both brake lines from the master cylinder, and quickly plug them with caps or fittings to prevent fluid loss.
6. Open Bleeder Screws:
This step varies depending on your brake system. However, on a 1993 Honda Accord, there are usually four bleeder screws located near each wheel. Open each bleeder screw slightly to allow the remaining brake fluid to drain.
7. Refill Master Cylinder:
While the bleeder screws are open, refill the master cylinder reservoir with fresh brake fluid. This helps push the old fluid out of the system and prevents air from entering.
8. Close Bleeder Screws:
Once the fluid level in the master cylinder reservoir remains steady, close all bleeder screws tightly.
9. Reconnect Brake Lines:
Reconnect the previously disconnected brake lines to the master cylinder, making sure they are secure and that the fittings are tight.
10. Bleed Brake System:
Follow a proper brake bleeding procedure to remove any air bubbles trapped in the system. This involves opening and closing the bleeder screws while adding fluid to the master cylinder.
11. Check Fluid Level:
Make sure the brake fluid level in the master cylinder reservoir is between the minimum and maximum marks. If necessary, add some more brake fluid.
12. Clean Up:
Use brake cleaner and a rag to clean any spilled fluid. Be sure to dispose of the old brake fluid properly, as it can be harmful to the environment.
13. Test Brakes:
Gently press the brake pedal to ensure proper function. The brake pedal should feel firm and responsive.
Note:
Some 1993 Honda Accords may have a different brake system setup, so it is always best to refer to your vehicle's owner's manual or a reliable repair manual for specific instructions and diagrams related to your model. Brake fluid can be toxic and cause skin irritation, so wear appropriate protective gloves and glasses while performing this task.
