In last week’s blog, we talked about the definitions, common problems and quick fixes for the air filter and alternator. This week in our car A-Z series, we kick off with the battery.
Battery
Definition: We all know that the battery is a critical element of the engine. As soon as we turn the ignition on, the battery gets the engine started. It also supports the alternator in providing power to the electrics if needed.
Common problems: Most of us have experienced battery problems at some point. Because of this, it really helps to know a bit about the main issues that can arise. If your car won’t start, a flat battery is the most likely problem. Try using the electrics in the car; if they are dead or sluggish, it is almost definitely the battery. A jump start from another vehicle will give the battery enough power to start the engine. Keep the engine running for as long as you can; this will allow the alternator to power the battery back up.
The most common reason for a flat battery is that something has drained it, such as electrics being left on, or the car hasn’t been used for a while and the battery has discharged itself. If you know your battery is old, if it looks corroded, or if it often loses power without explanation, head to your local garage. Your mechanic will be able to check the condition of the battery and install a new one if needed.
Quick fix: It is easy to jump start a vehicle as long as you have access to another vehicle and you have jump leads. However, if your battery is beyond repair, it will need replacing. You can do this yourself or head to a local garage for support.
Brakes
Definition: If you don’t know what your brakes do, you shouldn’t be driving!
Common problems: Most brake systems consist of a rotor, calliper and pair of pads for each wheel. Common problems include sticking brake calliper, low brake fluid or worn brake pads. Worn brake pads are the most common issue, and they need to be replaced at about every 25,000 miles, depending on how you drive. Your garage will check your brake pads at MOT and service. If you notice a grinding noise when you brake, or if you notice that your braking is a little sluggish, it is best to get it checked out right away.
Quick fix: It is relatively easy to top up your brake fluids, however more mechanical repairs really need to be done by your local garage. Your brakes should be checked as part of your MOT. If your garage notices that the brake pads are a little low, they may add an advisory to your MOT certificate, which will let you know you will need to get them done soon.
