Ways to Remove and Install Bleed Screw and Adapter Fittings
There are ways to remove and install bleed screw and adapter fittings Listed below are the instruction you need to follow. Just make sure to prepare all the tools needed. Don't forget to wear your eye protection and gloves before starting the process. This will avoid you from experiencing eye irritation due to brake fluid. In case of eye contact, immediately flush your eyes with water for at least 20 minutes. If irritation persists, please get immediate medical attention to prevent further damage to your eyes.
Difficulty level: Moderate
What you'll need:
- Safety glasses
- Rubber gloves
- Brake bleeder wrench
- Jack stands
- Pressure bleeder
For calipers that have adapter fittings installed in caliper housing:
Step 1: Carefully remove all the damaged bleed screws and adapters.
Step 2: Check if there's still Teflon tape around the threaded ports in the caliper housing.
Step 3: Take note not to use Teflon tape on bleed screw threads. Just put a Teflon tape to the threads on bleed screw adapter and install it in caliper housing.
Step 4: Using your brake bleeder wrench, install the bleed screw and tighten it to 40-50 inch pounds. Just a tip, you can loosen and re-tighten the screw for about three to four times to achieve a good sitting contact between the adapter and screw. Just make sure to reach 40-50 inch pounds.
Step 5: You need to bleed the system to remove all air in it. This will also avoid the brake pedal to become soft.
Step 6: Don' forget to check for leaks by pressurizing the system. While doing this, carefully observe the bleed screws. If you notice a leak, repeat loosening and re-tightening the screws to 40-50 inch pounds several times.
For calipers that have bleed screws installed directly into the
Caliper housing, without adapter fittings:
Step 1: Take away all the damaged bleed screws.
Step 2: Using your wrench, install the new screws and tighten them to 40-50 inch pounds as well.
Step 3: If the screws are not well seated, you might need to loosen and re-tighten them again for about three to four times or until the screws are correctly seated within the housing.
Step 4: Same as the other aforementioned method, you will need to bleed the system to remove all air in it.
Step 5: Pressurize the system and check if there are leaks. Once you notice leaks, slacken off and tighten the screws some more, following the golden rule of reaching 40 or 50 inch pounds. By doing so, you'll be able to form a good seat which will eliminate leaking problems.
Before proceeding with this procedure, make sure to be equipped with all the knowledge you need to know in order to properly remove the bleed screws, the do's and don'ts of pressurizing the brake system, and all other related matters. If you are not confident in doing this DIY project, don't push it. Ask for professional help to avoid further damage in some other parts of your vehicle.
