Road Trip Checklist - Part 2: Brakes & Battery

在进行公路旅行或逍遥游览之前,需要几分钟的时间来对您的车辆执行一些简单的安全检查。在我们的道路旅行清单的第2部分中,我们将介绍制动器和电池的基本检查。

Even though we're all driving less than usual due to coronavirus restrictions, many of us will be relying on our vehicles for a vacation or extended road trip. Being stranded anywhere is an unpleasant experience, but it's even worse when it happens in an unfamiliar environment. To minimize the risk of that happening, we can perform a series of inspections to identify potential issues before they have a chance to ruin a much-needed getaway.

If you missed我们的公路旅行清单第1部分,一定要检查一下。Part 3 of our checklist处理保持关键的液体。第4部分包括灯光和过滤器。

制动器是任何汽车的关键安全部件,因此在您在公路旅行时确保它们处于良好状态。制动器的检验过程比检查轮胎的涉及更多,但它相当简单。注意:这些说明用于配备有圆盘式制动器的车辆和带有足够间隙的轮子以查看卡钳。如果您的车辆有鼓式制动器或带有HUBCAPS的钢轮,您需要咨询机械师。

  • Check brake pads

In order to inspect the brake pads, you'll need a制动垫测量工具- 我们建议的那个具有绿色黄色码的多个仪表。让你的生活更轻松,你可能想要一个高输出手电筒A.mirroras well. While you can check the brakes at any time, we recommend doing so before the vehicle has been driven. Brakes get extremely hot during normal usage, so checking when they're cold will minimize the risk of burning yourself. Start by positioning the wheels in such a way where you can see the caliper directly. You may need a spotter to help you with this step, since it's not usually possible to see the wheels when you're sitting in the car.

The pads you’re measuring sit directly under the caliper, and the gauge will measure the amount of material present on top of the backing plate. The angle of the feeler gauge should allow you to press the edge flush against the rotor; from there, slide it towards the caliper until it contacts the pad. Start with the thinnest gauge (the first red gauge of the bunch) and work your way up, stopping when the feeler gauge fits snugly with no play. The number on the last gauge that fits is your pad thickness measurement. Inspect the other three corners; if the green gauges fit in all of them, you’re good to go. If the yellow ones are all that can fit, you’ll probably need the brakes serviced when you get back from your trip. If you can’t fit anything more than the red feeler gauges, make sure to get a brake job done before heading out on your trip.

  • Check rotors for damage or wear

虽然您在汽车的每个角落测量焊盘时,请留下一两个并检查制动转子的表面。它们应该均匀地磨损,没有明显的缺陷。如果您看到斑块变色,则表示转子在某些时候过热。转子上存在显着的同心凹槽,指向焊盘和转子之间的异物。如果您注意到这些条件中的任何一个,请通过专业人员检查。

Next, we'll move on to the battery. There are three components to a proper battery inspection: visual, physical, and performing a load test.

  • 可视电池检查

Visually inspecting the battery starts with looking at the battery itself. If it’s been a while since you’ve checked it, it’s highly likely that it’s covered in dirt and dust from the road. Don’t worry, the dirt won’t affect performance. Brush the dirt off to make the labels on top legible. There should be a date stamp indicating a month and year. A car battery will typically provide 5-6 years of reliable service; if the date stamp indicates your battery is older than that, consider replacing the battery to avoid potentially being stranded in an unfamiliar environment.

如果日期范围在5 - 6年内落下,请继续前进并检查其余的电池。首先,查看帖子和终端 - 这是电缆附加到的部分。您可能需要翻转或删除保护盖以查看终端。确保它们干净,没有腐蚀。后者常常似乎是一个类似于泡沫的鲜艳的地壳。如果终端在表面上脏或腐蚀,则可以轻松清洁它们。你所需要的只是少量电池清洁器A.钢丝刷to start the job. Spray down the corrosion with the cleaner and let it sink in for a few seconds, then scrub lightly with the brush. Note: if there’s heavy corrosion, you may need to replace the terminals and/or the battery due to irreversible damage.

  • 物理电池检查

电池检查的物理部分需要几个手动工具:a套筒扳手和10mm插座(或者可能需要12毫米,具体取决于制作和型号)。确保终端坐在很好,紧密,并检查是否对电池柱进行任何播放。如果它松动,请使用套筒扳手轻轻转动螺母。但是,不要过度收紧终端 - 这种风险损坏了帖子。手紧缩足以将终端固定到柱子以防止其退缩。

Next, check the tie-down for play - there shouldn’t be any at all. You’d be surprised at how heavy car batteries are, and you certainly don’t want it moving around while driving. If it's loose, use the socket wrench to cinch it tight. If the battery can still be moved after tightening the tie-down, this indicates an incorrectly-sized battery or a damaged tie-down.

  • 测试电池

The final inspection consists of performing a load test. You’ll need abattery load testerfor this part. Many testers (including the one we recommend) will walk you through this process, so it’s pretty easy to perform even if you’ve never done it before. The tester will typically ask you what kind of battery is in the car, whether it’s installed in the car or not, and the CCA (cold cranking amps) rating. The technical information can be found on the labels that were cleaned off earlier.

大多数汽车和卡车都配备了工厂的“洪水”型电池;这些包含浸没在酸中的细胞。高级汽车 - 通常来自欧洲制造 - 往往配备AGM(吸收剂玻璃垫)电池;它们看起来与外面相似,其中一个例外 - 有一个悬挂在顶部或侧面的通风管。他们通常也会在信息贴纸上标记为“agm”。

检查电池是否安装在汽车中,或者不是非常自我解释 - 如果您正在测试独立电池,则清楚地未安装。最后,我们需要将额定的CCA输入到测试仪中。阅读此信息的电池标签,确保使用“CCA”图(一些电池包括制造商提供的CCA和标准曲柄AMPS)。

大多数测试人员将提供通行证或失败结果;如果电池电量太接靠近失败的负载测试,有些可能提供“警告”指示器。如果电池由于负载测试而导致,您肯定希望在进行旅行之前更换电池。您可能希望考虑打包一个便携式跳转启动器无论如何,为了增加安心,因为即使是一个健康的电池也可以通过留下灯光的东西来过夜。
