Ok....I had an incident last 2 weeks that I have never experienced before. I was taking a leisurely drive after work to the store when I noticed something wasn't right. My hilux seemed to pull a little to the left and just seemed underpowered. I pulled over and saw some smoke coming up from underneath the hood. To my surprise (and relief it wasn't something else)....it was because the left front disc brakes were extremely hot. Apparently, they were sticking and friction was doing what it does best....create heat and frustration. The rotors were literally about as hot as I could imagine them being without catching everything on fire. Given I was in no hurry....I just pulled over and allowed them to cool. I couldn't believe that they would hiss water being sprayed on them for what seemed like a long time. I managed to soak them in some deep creep to help them cool and free up whatever was stuck. I just keep on spraying water on that brake until there's are no smoke and straight away go home but the problem is keep on going and now I need to prepare a bottle and whenever I want to pulled over, that place must have a water.

Based on what I described....what exactly happened here? I realize that the brakes on that ONE wheel were stuck...but what would cause this? Is there anything specific I need to check for to see if the heat caused something to need replacement? I realize the rotor and pads would be obvious suspects for needing to be replaced after this incident....but they seem ok (to my amazement).

Thanks for any and all comments.

OMG please dont spray cold water on an overheated brake.
they would crack

not a cold water, a water from drain or any water I can find near the road, so basically what the main problem?is it the brake master cylinder or the brake caliper didn't work well?

sounds like your left brake may have jammed.
causing it to rub against your rotors as you drive = overheating
you should send them to be checked. tyre shop will do, or mechanic as the better choice.

I also were thinking like that because last time I send it to a workshop they asked me to change the brake master cylinder without check the brake caliper, it surely cost more and to make thing worst, I'm currently working in Cambodia and the mechanic can't understand english words. I just don't want to spend my money on things that not exactly the problem because they see me as a foreigner in their country and surely they will asked me to pay more

Last time got this problem on my father's unser. The culprit is a jam caliper.
If master cylinder at fault should be other brake jam also?

yea, I thought so if the master cylinder got problem, surely all brake should have problem because it control all the brake system, I'm kinda a noob in car parts but that's what I understand from the diagram shows in the internet about car brake system. In that case I will ask the mechanic to check on the caliper rather than replace the master cylinder which can cost me hundreds dollar maybe

You should have lit a ciggie like a BOSS.. on red hot brake disc.. and post on 9gag..

On a serious note, your brake caliper jammed. Normal problem if the seals are no longer holding the brake piston in position and it jams against the brake cylinder wall. Usually can be fixed with a service kit if it is available.

Being in a foreign country would be a problem. Ever though of going back to Toyota in Cambodia? At least you won't get so ripped off.

try looking at the brake hose & see any sign of deterioration. the fluid might stuck there.

Last time I already go to the Toyota Service Center and they quote me USD 400 only for brake system so I opt to go to local mechanic but unluckily they can't even speak english beside 'OK' and 'NO OK'

That is why I said.. 'at least you won't get so ripped off'.. the 'ok no ok' mech might rip you off more.. even your life if his skills as a mech is as 'no ok' as his english.

should be the caliper piston jam already...when its hot,then it not advise to pour water on your disc rotor,rotor will be crack .

Maybe you need change or skim your rotor as well.

Possibilities are few, but the highest possibilities are either
- Brake caliper jam
- Master pump jam

And seeing that you poured water on your brakes when it was smoking hot, most probably your discs had to be changed also. Brake pads also have to change since it got overheated.

It's normal for brakes to go that hot. Brakes are meant to withstand temperatures in excess of 500c mind you, water boils at 100c. Your normal stop-go city driving is enough to bring your discs above 100c mind you.

Don't care cold water or hot water, water is still water and below 100c. When you pour water on your disc, it causes instant localised cooling which will stress your discs, possibly bending or cracking it due to uneven expansion/contraction throughout the disc surface. Which is why driving through puddles after a hard drive can cause your discs to warp.

Really??? adeiii..my working place is about 200KM from Phnom Penh city but usually it takes 3 hours to reach if I wanna go to the proper workshop and furthermore if my local driving the car, he will always stop to pour the water into it as long as he feel the car moving not fast enough, maybe this monday I should go there before my driver pour more water and cracks it

Added on October 20, 2012, 12:22 pmUsually what the cost for change the disc brake in Malaysia??I need to do some calculation if I want to change here because right now, I can only afford USD 200 for the brake if I were going to change it

yes do not have anyone pouring water to your discs help.

also usd 200? not ringgit malaysia? usd 200 can get you new brake discs with some DAMN GOOD EBC brakepads to go as well

what is your car model/make btw?

yes because I'm in Cambodia now so need to consider if they import it from outside the price might higher than Malaysia. My car model is Toyota Hilux 3.0D, 2007 model
