Toyota dealership .

Don't need all that electriconics bullshit. that's bullshit to make cars fail. they make them redundant best to pull all the crap off and throw it away what I do I fit manual pump and it all good, don't need electriconics bullshit now my hilux 1981 its all good with no electrics,, people stupid to have electronics crap all over their truck. don't need that crap. I show people how to fix cars but they dont believe me. thay dont know nothing here in this country. back in switerland we fix cars right and have wof that they check things right too.
Don't need all that electriconoics bullshit just take it off and throw it away.

i keep wondereing why? did intrade . " I showed the women my tool".

Well i think intrade should be given credit for *upskilling* and having a meter to check water content.
And me bein old skool and simply take one look at fluid.
Maybe it is about time old skool and new hitech
Combined.
.I.E.
Next time ya do a fluid change intrade.
Not only dip ya tool in the master cyl.
But. When ya change out dat fluid.
Simply bleed each wheel and bleed in to a container and dip ya tool in .
And post results.
(Experience tells me that when ya have 4% in a master cylnder reservoir the fluid you drain/remove bleed out of the calipers will be more cruddy and same with the rear wheel cylnders. )
Results WILL be interesting.

Me too,

Clearly not a mechanic checking vital components on a vehicle with a braking and a cooling system

I see that Intrade is now suggesting in threads that some people aren't real mechanics because they never change brake fluid. I'm thinking that's me he is talking about.
Well Intrade, if you could read a bit better you'd have seen that I never said that, and that in fact I said I did change brake fluid, when it's dirty or changing viscosity. I don't use any fancy tool because I don't need to.

The fact is Intrade, that this idea we should change fluid on a schedule, and of two years, is a scam given the sealed systems we have these days. It's part of that swap-a-tron, fit every part you can to bump the price up so you can cover the lost time when you stuff up bullshit that is these days portrayed as being professional.
The whole concept of professional is not that you are in the trade, or charge for what you do, or even that you change every thing without indiscrimination and with out good reason. Being professional is knowing the theory of what you do in a complicated occupation, and then applying that knowledge in such a way that you can demonstrate that you've been careful, that you've followed the correct diagnosis and logic to find the problem in a timely manner, then used your experience and discretion to bring about the desired result in a pragmatic and justifiable way.

In the case of this brake fluid. I have been a mechanic for forty-five years, and self employed for forty of them. I've worked in a small community with all regular customers, some of which I've had for forty years, and many for twenty five and more. They are people that don't do a lot of miles, and keep their cars for a long time, as I do. I know that brake fluid goes very slowly off colour these days, from the bright gold to slightly brown then eventually distinctly brown tinge with little of the golden in it any more. By the time it's getting slightly brown you can tell the viscosity has changed with your finger. you don't need to poke your tool in it. In the old days before sealed systems the fluid did get dis-coloured quickly, and after about five years it could be getting towards that black colour the fluid in that car you were talking about had. But these days, with sealed systems, i reckon it probably takes about near fifteen years to get like that. I know that my two cars haven't had a fluid change in the ten and twelve years I've had them, and their fluid is brown, and due for a change, but I don't think it's going to be black for a few more years yet.

What all this means Intrade, is that that fluid that showed four percent water. was probably over ten and maybe near fifteen years old, and it had taken that long to get to that stage, and, you didn't mention the cylinders being rusted and leaking as the problem. In the old days master cylinders and wheel cylinders didn't last long, they used to rust and score the rubbers. These days the rubbers age and wear away but it takes years. I know of lots of cars that will have their original master cylinder and they will be twenty years old. If we leave the lids on and only take them off when we see through the clear plastic that they are low, then fill them and reseal them, the fluid doesn't get contaminated anywhere the rate you say. I know it can and will if we leave a bottle unsealed, and it can do that, causing the viscosity change, in as little as a year, but not if it's sealed.

You should have a rethink about this Intrade, and you should have a rethink about making the snide remarks. If nothing else, you should remember and have some gratitude for the guy that introduced you to the idea of connecting a laptop to cars, and that gave you the programs and the autodata cds that set you off on this upskilling that you are now engaged in. You should realise that there are plenty here that have been on a life long upskilling process and that know a lot more than you do.

That's it. Apologies for the rant folks.

Very well said mech. That could apply to the odd few others on here spouting propaganda crap as well. for agenda driven purposes.
I'm in the same boat as you !

Thanks Ema.

And I saw you say the other day about the ease of repairing toyotas. I agree.
Time after time over the years I've made up a bill for a toyota and have been pleasantly surprised to find that the charge was really reasonable. It's because the parts are reasonable, and you don't have to replace too many parts, and the job goes really straightforwards time after time. there are never traps or difficulties. Unlike some makes which are full of pitfalls. including the japas which are all mostly fairly straight forward. but toyotas really are exceptionally good to work on in general. It's a pleasure as a self employed mechanic.

That's the main reason I've owned over a dozen of them in total so far. all have been excellent apart from one . a GX60 Cressida I bought as a spec project with an over heated engine( previous owner drove on with a split hose that let all the coolant out in a hurry. hardly the cars fault, stray piece of barbed wire lying on road getting tangled around bottom hose was cause oddly enough ) , bought a low mileage rear ended prang of the same model swapped out the engine/gearbox assembly in one piece and ran that car for another 100,000 plus km trouble free.
Besides that, of the Toyota's I had 7 of the GX60-GX61 and GX71 Crissida's/Grande's back 20-35 years ago. very advanced tech in them back then and reliable as into the bargain. and comfy beyond comparison with every convenience and "extra" as standard fitment . solid old buggers they were, lots of cockies down here used em on rough metal roads and even just tracks and they just loved them.
3 of the ones I had were cockies cars including the overheated one and the rear ended one I mentioned . got em both cheap and they owed me absolutely zilch in the time I had em. common sense design paid off big time on those Toyota's mech.
Running a low mileage Avalon and a Corolla currently, never stuck me up anywhere. they do everything I want from a car and more, I'm in the Toyota camp forever for the many reasons we have mentioned mech plus many more.
Those 7 Cressida's combined I did over a million kms in total. all with a smile on my face. they never failed me anywhere.

Lol. now that is a toyota nut !

My wife liked them. She had starlets for years. I live rural and drive subarus. have done for. er. about thirty years, before that it was all bikes for me.

Can't beat a toyo to work on though I reckon.

Toyota loved me when I worked for them for a year and a half. After three months they granted me a bonus as per our negotiations when I signed on, and allowed me to name the amount. After about nine months Bob Field and another guy were ringing me up to see if they could send cars to me to fix because nobody else could find the problems or was competent to fix them.
I did lots but the two jobs that stand out and which I'm proud of were, a cressida trans that nobody could diagnose the noise in, even though it had had a failed trans cooler and the noise was obviously torrent thrust bearings. What really chuffed me was that they said to over haul the whole thing(special customers) and the spare dept kept insisting that one particular clutch set were right when they weren't, they were too thick and would have locked up. I refused to use them and after about three days of arguing I rang BNT and asked if they could help me. They identified the plates I needed which were five thou thinner each, and then the spares contacted toyo japan to ask what's up. japan said, "Oh yeah there are some like that. There's a new box at Thames, we'll send it up and have Brett use those clutches, and when the parts arrive from japan he can overhaul that one too and send it back to thames to go into a new cressida. I thought that was a huge vote of confidence.
And the other job was for a business man with a fleet of toyotas and his private car had a noise since new and it was getting near end of warranty and he was getting gnarly about it. Nobody else in the whole of warranty had been able to find the noise. I found it with the guy within about ten minutes, explained it was exhaust resonance at certain revs, load and cornering and he was all satisfied and didn't even need it fixing. What chuffed me though was, Bob had told me, "you are our last chance. Don't let him go away dissatisfied. If you can't hear it, or figure what it is, or fix it, you are to offer him a new car off the showroom floor. ". I thought that again was a huge vote of confidence.

Good company that. And four years after I'd left, still nobody working for them was paid what they had been paying me the bush pig from Kaitaia. haha.

Basic knowledge, basic skills, and application.

That's it in a nutshell but add to that a common sense methodical way of working to a solution.
Thinking outside the square is a skill most of us old fellas had a good handle on . to an extent it's a skill sadly lacking these days somewhat. Re the trans noise not sure about this but wasn't there a service bulletin on that, not sure now if it was Toyota or was it GMH which I cut my teeth on, not clear on that anymore been years mech.

In agreement on one thing here TNZ are better than GM-(been with both) and re Toyota and bonuses yip was with Toyota in the 80's befpre Bob and bonuses are standard issue was pullin a coupla hundy in bonuses weekly back then

Slightly brown brake fluid in the master cyl.?
Wonders what colour it could be at wheel cylinders. Uumm

Probably about the same Jmma.

I left the searching through the service bulletins to the others Ema and got on with the work. That's why they paid me the bonus. Because I got so much done. and no stuff ups.

re#117 and #118 Therin IS the question that intrade can answer with his tool-(so ya cannae say e is a dick)
And as to a *hygroscopic *liquid having a cosistent water content throughout.[Adds toyota specify brake fluid change in service schedule gm do not]

Experience tells me the fluid will be the same colour all through Snoopy. More or less. it looks different in the dirty coke bottle after the bleed than what it does in the reservoir, but not by much. I suspect it's all the same colour.

Well my 2 cents worth, brake fluid doesn't recirculate, so by the time the dirty shit is in the resv. the rest in the system is had it.

How does Intrade's tool work. Electrical conductivity ? Chemical ? Optical ?

I look and dip a finger in. haha. mostly just look though.

Not only that-as posted prior by moi re adjusting and bleeding rear brakes due to *atmosheric ingression** in rear wheel cylnders with *wipe seals* As opposed to having to bleed disc calipers with a square setion seal.
And when the brake fluid is capable of ingressing moisture through brake hoses(rubber-permeable) and cylnder seals.
But .
SOMEONE DIGS A HOLE AND CLAIMS ONLY THE MASTER CYLNDER CAP.
mmmmm

Snoopy. don't you think that if your theory about those cup washers is correct, that brakes systems would be constantly getting air into them ?

How come air doesn't get sucked into the master cylinder every time we let our foot off the brakes ?

Think it through Snoopy. apply a little logic.

And those rubber hoses. why would they let air or moisture permeate in under atmospheric pressure, when they don't let the brake fluid out under a thousand pounds of pressure.
