When last did you do a drain and replace? Brake Fluid Flush (aka Drain and Replace) |

Is there a need to drain?? I was thinking if it not up to gauge,You just top up 5 Likes 1 Share |

Reason for thread: Customer complaint, after repeated hard stops, brake pedal travel increases tremendously Reason: too much moisture in the brake fluid causing it to turn into gas and making it compressible, gas is compressible, liquid far less so! As a result total loss of braking power, even replacing brake pads did not make a difference...full braking force returned as soon as the brake fluid cooled down To avoid a situation like this, consult your manufacturer manual and replace brake fluid as per their specifications or using a commonsense schedule of every 20,000 miles or 2 years to be safe If you are paranoid, you can replace it sooner, by sooner as soon as you notice the brake fluid has boiled, it also means that your brake fluid would have lost some of its effectiveness and also by extension, you have also lost braking power/ability. Could this be the reason for some accidents on our roads? The mechanic he consulted suggested that the brake fluid is ok and that the ABS is faulty and should be disconnected. Could this also be one reason why brake components could fail and require their replacement? Food for thought and remember, a driver is only good if he can stop the vehicle at any and all times and that job is done by brake components of which the brake fluid is a very necessary soft part which should never be taken for granted! Engine oil does not necessarily go bad after 3,000 or 5,000 miles yet many change it, but many never consider changing brake fluid...is that not a rather worrying contradiction in service practices? 6 Likes 1 Share |

AutoElectNG: Actually not absolute. Liquids are compressible, otherwise shock and sound waves would not exist. Also. should liquid remain incompressible, Bermoulli would not have ASSUMED that fluid is incompressible in his bernoulli theorem in fluid dynamics. Another principle worthy of note is the compressibility modulus.... let me stop diverting biko who fluid dynamics epp for this election season 12 Likes |

Hopefully, get to know the type of fluid your vehicle use before you drain it so you do not put the wrong one and cause harm while trying to cause good... 1 Like |

deepwater: Beauty and brains! My dad used to say go for a lady who will excite both your loins and your mind. You certainly fall into that class. That said you are right. My point is, gasses are more compressible than liquids. Is that correct? https://physics.stackexchange.com/questions/96577/why-are-oxygen-and-hydrogen-compressible-but-water-is-barely-compressible 1 Like |
Re: Let's Talk About Brake Fluid! by HeavenlyBang(m): 8:19am On Oct 03, 2018 |
deepwater: It all depends. Everything is compressible under the right conditions. How much energy is require and how effective the compression is, are entirely different issues. That said, just like you pointed out, liquids are assumed to be incompressible because compressing them just isn't worth the hassle at the end of the day. 1 Like |

Re: Let's Talk About Brake Fluid! by obailala(m): 8:23am On Oct 03, 2018 |
AutoElectNG:You're absolutely right about this. The chemical used as brake fluid in cars is hygroscopic, i.e. it absorbs moisture over time and that can make it inefficient. Brake fluid usually gets very very hot; so in order for it not to boil in operation, the hydraulic used has to be something which has a very high boiling point. But when the fluid absorbs excess moisture over time, upon heating to just 100degs, the water in the fluid boils and becomes gas, thereby increasing the compressibility of the overall fluid which consequently results in less efficient braking. Another consequence of excess moisture in brake hydraulic is corrosion. With excess water in the fluid, it becomes corrosive and you could risk corroding your braking components. I know all of these, but then, everytime I go for a full service of my car, I'm usually told my brake fluid has much moisture and needs changing. But as an African man who's naturally 'reactive' in nature, after they quote the price to change the fluid, I just tell them to forget it; after all they've been telling me the same thing for 3 years now and my brake hasn't failed for once. 2 Likes |
