Vehicle braking system fade, or brake fade, is the reduction in stopping pow

any vehicle that utilizes a friction braking system including automobiles,

今天自己检查并处理了rear drum brake,希望对缺少经验的xdjm有所帮助。至于我车
子brake问题 (刹车时有刺耳的声音),在另一主题下有较为详细说明(参见:http://www.mitbbs.com/article_t/Automobile/32392619.html)。本人经验有限,不对或遗漏的地方欢迎
大家指正。
第一步,拆卸hub cap.对于没有螺丝紧固件的hub cap,直接用手抠住hub cap的某一肋
扳,沿边缘用力向外拽即可。
第二步,拆卸轮胎。先用扳子把5个紧固螺母拧松。如果螺母很紧,可以用脚踩住扳子
的一头,慢慢松开螺丝(注意安全)。这时候不要把螺母拧的过松。待5个螺母拧松后
,支起千斤顶(具体位置看
manual)。在支千斤顶的时候,观察轮胎高度,当轮胎底部脱离地面一段距离(我的情
况是1-2cm)后,即可把螺母完全拧下来。安全起见,可以在jack支起到一定高度后支
上jack stand。不过即便如此,也不建议钻到车底工作,以免危机人身安全。螺母拧下
后,将轮胎取下,就看到drum了。
第三步,拆卸drum。在拆卸drum之前,需要将parkin... 阅读全帖

我手欠,帮你搜了一下
Adding vs. Changing Brake Fluid
Adding brake fluid is usually not part of routine vehicle maintenance. Low
brake fluid typically means that your brake pads are low and soon need to be
changed. If you notice a sudden drop in the brake fluid level, it could
indicate a problem with your brake system, or that you simply need to change
your brakes.
Have a professional check your brakes if you are unsure. If you are sure
that your brake pads are in serviceable condition and your brake fluid... 阅读全帖

回国一个月,回来后发现仪表盘上的brake灯有时候会亮
(似乎是早上天冷的时候亮,其他时候亮得少),考虑到4个月前
换机油的时候,dealer就说brake pad近期需要换(当时说还有4mm,最低要求2mm)。
刚下去看了下brake fluid液面,还在min线以上3mm左右;不过看液面的时候太阳
已经很高,天气也暖和了,可能液面也上升了些吧。
觉得brake灯亮应该是brake pad太薄了的原因。
在小镇上寻了个价,换brake pad最便宜也要200,倒是flushing NY的中国店只要75,
而且那个中国店大家都去,都说不错来着。
打算明天开50mile去那个中国店换brake pad,可能还会换掉brake fluid。
不知道在brake灯亮的情况下,开车50mile问题大不?不会有啥意外吧?
多谢指点:)

brake fluid 我有点经验。
Hyundai Accent。我用的Dealer比较贪婪,从来都是推荐一大堆维护,浪费了很多钱以
后就一概不理了。所有的建议我都回家上网查资料,看看网上说这个维护重要与否,不
重要而且没症状就不做。Dealer也曾经推荐过brake fluid,没做。因为网上说这brake
fluid很多年才需要一换,有的车从来不用换。
我的 Hyundai Accent有段时间刹车总有点打滑(尤其是雨天)。检查刹车皮也没事情
。大概1年以后我才换了brake fluid,可以说是心血来潮。换过以后,刹车再也没打过
滑。可见我的brake fluid 含水量早就过量了。含水量大,brake fluid刹车的时候不
能维持体积,所以刹车会打滑。
所以事实上,我之前做了非常错误的选择。brake fluid早该换了。思之极恐。
所以我的建议是,至少你要保证你的brake fluid是好的。4~5年换一次不亏。一旦出现
有点打滑,如果不是刹车的问题,立刻换。毕竟这关系到车上最重要的保命措施。

来自主题: _Auto_Fans版 - 请教一下自动档车的engine brake逻辑
你说的也有道理。from wiki
To stop the wheel, friction material in the form of brake pads, mounted on a
device called a brake caliper, is forced mechanically, hydraulically,
pneumatically, or electromagnetically against both sides of the disc.
Friction causes the disc and attached wheel to slow or stop. Brakes convert
motion to heat, and if the brakes get too hot, they become less effective, a
phenomenon known as brake fade.

我也是新手,和新手共勉吧。
我之前换过的车,手刹(parking brake)和脚刹(brake pad)都是控制的一套brake

幸亏当时周围每车,一头撞在雪堆里,还好人没事,没撞到人
拖到修车铺,检查半天,说是后轮胎的什么brake进入了空气,导致失灵

Generally, you will find most front disc brake pads last about 25,000-
30,000 miles if they are serviced right. However there are many factors
that can add or subract from this. The factors include weight of vehicle,
city or highwaty driving, driving habits, if rear brakes are kept in
adjustment, If the brakes were installed correctly. I have seen some go

http://en.wikipedia.org/wiki/Braking_distance
里面braking distance只和速度,轮胎摩擦系数和g有关。那么好的brake pads和rotor
的贡献在哪里?分有abs和没有两种情况。没有abs,一脚踩死,可以理解。但是有abs
的情况下,难道不应该好的brake pads和rotor可以减少braking distance么?如果在
不是那么紧急的情况下,就算没有abs,好的pads和rotor也应该减少braking distance
吧?
最后,pads和rotor抱死以后为什么就没有steering control了?这个不很明白。

来自主题: Automobile版 - 庆祝换rear brake pad成功~~ ...
昨天晚上去alldatadiy打印了更换方法,去advanceautoparts买了brake pad,去sears买了craftsman的工具箱和torque wrench,万事俱备。今天早上起来就准备换brake pad。
先用torquewrench把后轮螺丝放松,再按照后备箱里的说明用jack把车顶起来,顶到车轮离地,螺丝刀可以在车轮下自由来回为止。然后用wrench把车轮螺丝卸下来,把车胎拿下来放一边。
接着按照说明把caliper的两个固定螺丝卸掉,把caliper上端从rotor上转开,再把下端移开。这时说明书说要用个东西支撑caliper,免得连着的刹车油橡胶管断裂。想了一下就把卸下来的轮胎移到brake下面,再放上刹车皮的包装盒,高度刚好能支撑caliper。然后把rotor从车轮螺栓上拿下来,检查后面的brake shoes和其他配件,觉得除了锈了一点之外一切正常。用towel加cleaner清洁了一下,就把rotor挂回去了。
接着研究caliper,发现两块内外brake pad是用金属cliper卡在caliper和piston上面的,用螺丝刀稍微用点力气就撬

来自主题: Automobile版 - Is the disc brake safer than drum brake?
Generally speaking, yes. but it's not that easy.
disc brake比drum brake好的地方并不在制动力上,而在散热上。如果长时间连续使用
制动,则制动盘/鼓的温度会比较高,盘式制动散热很好,鼓式制动散热不好容易过热
,一旦过热则会造成热衰减,严重的刹车会失灵。其实最重要的还是驾驶员自己。如果
总是喜欢用制动而不用发动机制动,则就算是盘式制动也会过热的;反之如果合理使用
制动,则鼓式制动也并不一定不好。
影响brake distance的因素有很多,不一定是brake系统的问题。你的轮胎、减震器、
悬吊、引擎都是对制动系统有巨大影响的。如果轮胎纹深不足1.6mm则会在制动的时候
失去抓地力造成打滑,另外轮胎气压的影响也是巨大的;减震器悬吊不好的话制动时候车轮会有位
移而且在底盘上的着力
点会变化;引擎如果有vacuum leak的话真空助力鼓就得不到足够的真空,造成助力不
足。

You might only need to have the hand brake cable adjusted.
One set of brake pads should not cost that much.
Replace drum brake is a little more complicated than disc brake, but I know
some guys willing to do it for a six pack, so it is not that hard to do.

Some car (like VW and Audi) have 2 brake warning sign on dash.
The one with ! in the middle is the brake warning.
The one without the ! in the middle is the front brake pad warning (usually
will come on when there is 25% pad life left)
I am not sure which warning you are talking about, since you did not say
year, make and model of the your car.
But if your warning is for the brake pad, 25% pad life left is more than
enough for you to drive another 50 miles safely.

来自主题: Automobile版 - Is it the time to change the brake pads?
the car has a milage of 25,000 miles now. In the past 1 or 2 weeks, I began
to hear "Gua-Gua-Gua" sounds from the right-front side when I pressed the
brake. It's more obvious when the road is not that flat. Is it the brake pad
worn out now at the right-front wheel?
How muc it cost to have both brake pads changed, the rear ones are drum-
brake. Thanks a lot!

It is my understanding that stainless steel has very bad thermal
conductivity compared to gray cast iron, it gets very hot during braking and
it affects the friction, thus the ability to brake. There are specially
made stainless brake rotors but they are very expensive.
On the other hand, for your information, most brake rotors on motorcycles
are made of stainless steel.

我觉得其实lz最大的错误是在drive way上换brake。在斜坡上修车是大忌吧。
我自己换brake也是自己学一个人弄的,换完后自己心里没底,开出去的时候紧抓着
emergency brake,随时准备拉。。。

换过brake pads好几回了。没有一次需要bleed the brakes。只有
换caliper的时候才需要bleed the brakes。

来自主题: Automobile版 - 也抱怨一下brake masters的brake pad
在65k的时候换了刹车片,在brake master, 选的号称premium的pad, lifetime
warranty,~$130 (它家常年有coupon)。
结果只开了不到35k,这刹车片就快磨没了(我的开车习惯和路线都没变)。这premium
刹车片也太不劲磨了吧,只有原厂的一半寿命。
去了brake masters, 说要$100(含了warranty,用warranty 就不能用coupon,即使
那个coupon一年四季都有)。看来这个warranty也只值 $30。况且考虑到这个premium
pad的寿命,不值吧。
要是我自己花$50~60买个好点的pad(寿命应该比brake master的长吧),到别的店安
装可以吗? 大约会收多少?因为有ABS, TPMS等,不想自己换。

来自主题: Automobile版 - Brake fluid flush一般多少钱?
菜车nissan altima,有个刹车灯偶尔会亮。去dealer那里换油,说我的brake fluid
low & dirty,需要做个brake fluid flush,报价$120。
我打电话问了问sears,说brake fluid flush要$40,但不能直接给做,之前要brake
system evaluation收$15,那也比dealer那里便宜一半还多。sears换的话靠谱吧?
