Helpful Replacement Procedure for Your Vehicle’s Brake Accumulator
When it comes to helping your brakes engage quickly, you can count on your vehicle's brake accumulator to efficiently get the job done. It stores a sufficient amount of hydraulic pressure that's needed to make your brake system responsive. You can only imagine the disaster that it would cause once this component malfunctions. If your vehicle's brake accumulator has reached the end of its service life, you better replace it as soon as possible to keep the entire brake system working properly. To help you out, here are tools you need for this task and the procedures that you should follow:
Difficulty level: Difficult
Tools that you'll need:
- Hex tool
- Impact wrench
- Replacement brake accumulator
- Turkey baster
- Breaker bar
- Owner's manual
Step 1: Park your vehicle at a well-ventilated place where there's also enough lighting to help you get through this task effortlessly.
Step 2: Pop up the car's bonnet and locate its battery. You need to disconnect its negative cable to make sure that you don't get electrocuted while removing and reattaching the electrical connections of the brake accumulator.
Step 3: Pump the brake pedal for about 50 times to relieve its pressure. Make sure that you conduct this step to avoid any fatal accidents.
Step 4: Remove the screen from the reservoir and drain its content using the turkey baster. Doing this should make the whole procedure less messy.
Step 5: Disconnect the sensor wires that are attached to the brake fluid reservoir to get better access to the brake accumulator.
Step 6: Remove the faulty brake accumulator from your car. This part is tricky to accomplish since the brake accumulator is tightly secured over its mounting location. The components around it are also prone to getting damaged so be careful while you're doing this step. You need to use your breaker bar to pry the old brake accumulator out of place. Make sure that you store its bushings and washers on an organized area to keep them from going missing. To make this task easier for you, ask a friend to lend you a helping hand.
Step 7: Once you've successfully freed the brake accumulator from where it's mounted, carefully pull it out of your car.
Step 8: Install the new brake accumulator. Make sure that you torque up the fasteners properly. You may refer to your owner's manual to see the proper torque measurement.
Step 9: Plug the high pressure line back into place, and then secure the assembly onto its bracket.
Step 10: Tighten up the hydraulic lines by hand.
Step 11: Refasten the mounting bolts. Again, you should ensure that you apply just the right amount of torque on each one to keep them from coming loose.
Step 12: Place the screen back on the reservoir and refill it before reattaching it to your vehicle.
Step 13: Plug the negative battery cable back and turn on the engine. Allow it to run for a few minutes before taking it for a test ride.
Changing a damaged brake accumulator may take around two hours to finish. Don't forget to practice proper safety precautions!
