Problem: Article: If the front brakes have been squealing loudly, you may need pads only. If the car or brake pedal has been shaking when braking, you'll need to have the rotors resurfaced (called "turning"), or replace them.  If the car pulls to one side while braking, but stays straight otherwise, you may need calipers. This is a sign of uneven wear of your brake pads caused by uneven pressure in your brake lines. If the brakes have a grinding noise, this means rotors are done, spent, wasted, or whatever you want to call it, just replace them. There are two bolts that hold the caliper to the pad bracket, and two bolts that hold the pad bracket to the steering knuckle. You may need both SAE and Metric sizes of wrenches and sockets, as well as bleeder screw wrenches. Also, you may need a set of hex (ALLEN) or star (TORX) key wrenches or a hex or star bit socket set. Consider using line wrenches to remove calipers. Theses wrenches have a better bite and reduce the chances of rounding off hex nuts fitting on the hose end. You can always return what you don't use (keep your receipt and boxes and parts clean/undamaged). If you get caught without something while the car is apart, you may not have transportation to go buy anything.
Summary: Consider the symptoms of the brakes; for example: Determine the parts and tools you'll need. Buy more parts than you think you'll need.

In one sentence, describe what the following article is about: Don't initiate any contact with your ex, including phone calls, texts, emails, messages on social media, and in-person conversations. If he tries to initiate contact with you, don't respond.  Depending on the situation, you may want to respond to a text or email by simply telling your ex that you are not interested in talking to him. If he is being completely unreasonable, don't bother responding. If you are getting threatening messages from your ex or he is stalking you, report the behavior to the police immediately. You may be able to get a restraining order to keep him from contacting you or coming near you. If your ex-boyfriend will not stop calling, texting, or emailing you, you can block his number and email address. If he is very persistent and starts calling you from other people's phones or emailing you from different addresses, you might want to consider changing your phone number and/or email address. Most social media sites allow multiple options for blocking or ignoring a person. If you want to prevent your ex-boyfriend from viewing your profile and you want him to get the message that you don't want any contact with him, block him. If you don't want to take it to that extreme, but you also don't want to see any updates from your ex, ignore or unfollow him.  If possible, avoid places where you know you are likely to run into your ex. If this is not possible, just keep walking when you see him instead of stopping to talk. If you share mutual friends, have classes together, or work together, you might have no choice but to spend some time in the same room with your ex. It might be hard at first, but do your best to interact with everyone else in the room normally, and avoid talking to your ex as much as possible.  Don't go overboard by literally pretending not to see him. This will probably make him think that you're uncomfortable being around him, which is not what you want. Instead, address him as you would a stranger. Keep your interactions brief and avoid body language that suggests intimacy, like direct eye contact. If you're with a group of people, make an effort to talk to other people in the group instead of to your ex-boyfriend. If your ex starts talking to you, respond politely, but very briefly, so he will know you're not interested in talking. For example, if he says, "That math test was really hard. How do you think you did," just say, "Fine," and show no interest in continuing the conversation. If your ex-boyfriend tries to use other people to give you messages, respond according to the situation. If the messenger is your friend, just tell him that you're not interested in hearing what your ex has to say and you hope that he won't let that get in the way of your friendship. If the messenger is not your friend and has been sent by your ex to say something mean to you, just ignore him. If you're like most people, your boyfriend was probably the first person you went to for consolation when something bad happened to you, and also the first person you told when something exciting happened. This can make it very hard to let go of your ex because you may still feel like contacting him in these situations. Instead, try turning to a friend, a sibling, or a parent. It might be tempting to replace your ex with a new boyfriend, but don't do this unless you're really ready to commit yourself to a new relationship. If you do feel ready, then go ahead and date new people. It will be much easier to ignore your ex-boyfriend if you really are occupied with other things. Start doing more things with your friends, join a club, or take up a new hobby to get your mind off your ex and make ignoring him completely natural. If you and your ex-boyfriend are in the same social circles, it will help if he sees you looking happy and enjoying life without him. This will make him feel like none of the mean things he's been doing are having any effect on you.
Summary:
Avoid contact. Don't talk directly to him. Find new attachment figures. Stay busy.
