No they are two independent systems.... Brake system and cooling system... Brake ... Pads callipers... Oil etc master cylinder etc.
The cooling system consists of a radiator.. temperature sensor... Thermostat... Cooling fans ... And the coolant fluid..
They're absolutely apart.

Thanks sir , I still need more facts to tackle the man.

Brake binding can cause overheating issues though.

One of our company vehicles had an accident this morning due to break failure
It was towed back to office but everybody was surprise when the company company Mechanic said "The break failure might be as a result of Overheating "

Internet car gurus everywhere, so you also don't know that when you place you legs on your brake and it seems stiff, turning on the car engine makes it soften and goes down a bit more

So you're saying that even when a car engine goes gaga due to overheating in motion and you meet an emergency and depress the brakes it will still perform perfectly as when the engine is running fine. I've personally witnessed it on a couple of occasions oga, while driving and the vehicle overheats and the brakes also become stiffer and requires more pressing down to achieve desired results

At times it's best to leave commenting to the people who handle cars of different status on regular basis ie the mechanics/dealers, cos an issue which you've probably never experienced in all your years of driving your personal car is something they've had to encounter on a regular basis

For the OP, I might not have the diagrams or big grammar to illustrate my point, but your mechanic has a point, tnx

ZIMDRILL:


someone asked overheating on which part ?

the cooling system will never overheat becoz of brake binding but the dics/rotor will definately overheat


so which overheating is s/he asking about ?

mayor2013:


Who says. Don't forget when there is z binding brake depending on the degree your engine and transmission is over worked. What happens when its over worked?

Don't resort to Insults, it's only a shortcut out, kindly disprove all the points I stated above, tnx

binding of brake can never cause the engine or transmission to overheat

Vehicle info? With this I can comment.

Apparently,things happen differently on cars in naija and the UK





U also av a point too

GAZZUZZ:


the engine sits under the driver and front passenger. There is sufficient distance from engine to brake master, so in the event of engine overheating, the rise in temp should not cause a malfunction in the break master.

Over heating of the brake rotors caused by excessive braking could cause brake failure.

With my little knowledge,.. The day my car overheated,. I felt serious vibration on the brake.

Its best to just give your opinion without critisizing others.

The Vacuum booster or vacuum servo assists the driver in pushing the break pedal using the engine vacuum. I am not aware or cant imagine how high engine temperature could affect this system. As long as there is vacuum input, the servo should work fine.

However, i tend to agree with you that a loss of vacuum may seem to a less vigilant driver like the break has failed but may only need to press the pedal harder since there is no assist from the servo.

What i cannot relate is the connection between engine temperature and break system. I personally feel there is none.

Denn:


The mechanic and the driver are friends.

The mechanic is simply trying to protect his friend.

First, he claims the car was overheating. What is the procedure that a professional driver takes when the car overheats? Does he keep accelerating up to speeds that can cause serious damage via accident or drive slowly, park and sort the problem?

To those who mention hard brake pedal when engine is off and softer pedals when engine is running, it is simply the brake booster doing its work.

The only connection of a standard brake system to the engine is via a simple vacuum hose. The temperature of the engine has virtually no relationship with the brake system; except the car was literally burning and fire was gutting everything.

And by the way, was your fabled mechanic a forensic expert? How was he able to do a post-accident evaluation that made him conclude so confidently that engine overheating caused the accident?

Your company needs a more honest mechanic

I was once driving down from oshodi to ikeja on heavy traffic, was using my car AC too, suddenly I noticed I had to depress the brakes twice as hard to avoid hitting the vehicle in front of me, temperature gauge was still showing it at the middle where it should be (a fault with the gauge which I never knew about till this incidence occured), looking at the dashboard and everything seemed fine I kept driving and the brake stuff was getting worse and I was already contemplating on how to go and get my brakes checked out. Next thing I saw was vapor coming out of my bonnet and the hissing, alas, my car was overheating, quickly pulled off the road before engine went off and waited for it to cool off and bled with water before I continued.

Now, after this, the brakes went back to performing normally once more, now can you pls assist in providing an explanation as to why the incident with the brakes did happen. Vehicle in question was a 2004 Volvo S60, 2.4l turbo engine. I'll be waiting as this forms a major basis for my conviction that the mechanic the OP talked about do have a point.

Thanks

Denn:

I have a simple question in this line.

If you had coincidentally had a flat tire at that same time, would you have attributed it also as a consequence of over heating?

valarinz:


Like I said, I might not have the big grammar or plenty explanations of the car systems, cos naturally I despise long long stories, but like you pointed out, temporarily during that period of engine malfunction due to overheating the brake no longer performs well(due to the loss of vaccum), and you'll have to depress harder to get the desired result (mind you this is something I've experienced personally, not what I read on the internet), so as far as the mechanic is concerned, that's "brake failure" as a result of overheating, so, don't throw him under the bus, tnx
