How to Replace a Brake Vacuum Pump
A brake vacuum pump replacement is common when you upgrade the brakes or the motor in your car. It is essential to have no just for practical reasons, but also in terms of safety. The brake vacuum pump works to boost your braking so that when you need to stop your car quickly in an emergency situation, you are able to do so with ease. If you find yourself needing a new brake vacuum pump, it is possible to replace it on your own without having to bring it into a mechanic or dealership. Here are a few things that you will need, along with some steps that can help you through the process.
Step 1 - Familiarize Yourself
Begin by checking out the manual for your car so you know where all of the parts are. Be sure that you are looking closely at the parts that you will be specifically working with for this task. Gain access to the brake vacuum pump and check the parts around it to make sure that they all look to be in top shape.
Step 2 - Remove Pump
Begin by taking off the brake lines from the master cylinder. Remove both of the nuts that are connecting it and also the vacuum hose. Take each of the parts off one by one, being careful to either mark down on a paper or remember where each of them needs to go when you are putting everything together. Remove the actual master cylinder while you are there and then disconnect the actual brake pedal that is connected and finally remove the vacuum pump.
Step 3 - Install New Brake Vacuum Pump
Now you can clean out the area with a rag and then begin to install everything in reverse order. Hook up the vacuum pump and then connect the brake pedal and the master cylinder. Clean the parts as you go along since you are already in there working. Then attach the vacuum hose and both of the nuts that have been holding it together. Finally, reattach the brake lines where they were removed from.
Step 4 - Bleed Brakes
When everything has been put back together and you are sure of its placing you will need to bleed the brake lines. Then, test to make sure that everything is working properly. When testing, be sure that you are doing so in a close, residential area that is not busy. It is best to try just in the driveway at a slow speed in case there is something wrong. You do not want to get out on the highway and then have trouble breaking.
If at any time you feel as though there many be a problem, stop what you are doing and contact a professional. While this can definitely be done on your own, other problems can occur and they are better dealt with by someone with more experience.
