no because brakes get used a lot more on regular short journeys, so if you
are doing ten 5 mile journeys per day, this is worse than doing one 50 mile
journey, same goes for the fluids / suspension / steering etc

Mine is 19200 miles or two years

I think two years is what they deem the maximum life of the oil.

Mileage = Wear and tear due to usage
2 Years = deterioration due to age

And/or more wear and tear due to infrequent usage, always running cold etc.

Mine is one year or when the oil life indicator reaches zero.

The year is to allow for the usual brake checks and to replace the brake
fluid which is still hygroscopic even in two year servicing vehicles.

Mr Ford thinks that is how long brake fluid requires to pick up enough
water to be a problem.

Yep! That's so true. Many years ago when I was looking to buy another
secondhand car to replace our clapped out Cavalier, I test drove a couple
of candidate vehicles, both Ford Sierra models.

After trying the older of the two with more mileage on the clock, when I
test drove the newer one with less mileage, it became quite obvious that
the newer one must have done most of its mileage on local roads with lots
of potholes and junctions since the way it handled strongly suggested a
lot of wear on the suspension and steering, a sensation completely absent
from the older and cheaper model which was the one I chose to purchase.

I believe it was one of the last of the rear wheel drive versions with
the revamped trend setting jellymold and headlamp styling - just about
every other make of similar sized hatchback, it seemed to me, was
indistinguishable from the Sierra without benefit of a closer inspection.

You know how you start noticing the particular model of car you've just
bought that you'd never noticed previously? Well, I started noticing
other makes of car as well as my own (I noticed an awful lot more cars
than I did as a Beetle, Golf, Cavalier driver/owner).

Nope. You still need to change the oil even if you do very few
miles because the engine doesnt really get properly warmed
up if you only do a few short trips that doesnt warm the engine
up properly.

Yes, just miles or years is still a pretty crude way to determine
whether the oil needs to be changed, but it isn't viable to actually
test the oil to see if it needs changing so adding the years is
better than just using the miles.

Nope. Startups are very hard on I/C engines and time is a reasonable
proxy for that.

Come to think of it tho, with modern computer controlled
cars, it makes a lot more sense for the computer to keep
track of the number of starts and how warmed up the
engine got and tell you when to change the oil rather
than to just use a very crude do it every 2 years with
the cars that don’t make the miles required in 2 years.

Hah.
You'd think that with an electric car most of these problems would be history.
But no.
My I-MIEV is 10,000 miles. or one year. (WTF?)
There's no oil/air filter.
But they want to change the oil in the simple reduction gearbox/diff unit.
Sounds like job creation to me.

Nope. Lets say the van's only used very occasionally, for whatever
reason. It's 10 years old, and still only has 20k on it. By your logic,
it would never ever have seen the inside of a workshop in all that time.

Apart from anything else, brake fluid should be replaced at two year

I think the main reasoning is that, with a mineral oil, water which
condenses in the system works its way down to the lowest region, i.e.
the cylinders. These will then corrode. Also, because the boiling point
of glycol is significantly higher than water, if you get the brakes
really hot (e.g. during a long descent with a caravan?) the water boils
sooner, giving you a steam bubble in the pipe (and hence no brakes).

The classic Citroen system which uses mineral oil for suspension and
brakes is a circulating system (although ATM I don't recall if it
circulates down to the brake cylinders).

No. A vehicle which does short journeys - say mainly start stop in town -
needs more frequent servicing than one which cruises the motorway. And the
one doing short journeys will inevitably cover less miles.

this way.

I had one car where the foot brake failed, the pedal broke at the pivot.

Well, yes, you can do that. Then you can be surprised when the hygrometer
tells you it IS due for replacement, and you find that the bleed nipples
are all seized. Still, on something where minimising service costs in the
short term is a higher priority for the manufacturer than long term
maintenance, it's not a great surprise that they'd recommend such penny-
pinching.

No, the usual DOT 3/4/5.1 is still just as hygroscopic as it ever was.

Because it's ethylene-glycol based.

I have distant memories of issues between the fluid used in French cars
and the brake piston seals on others. Vegetable/mineral origins etc.

Hydraulic Citroens used LHM - bright green - which is mineral based and
non-hygroscopic. But it isn't compatible with the seals used in DOT-based
systems.

Surely things have moved on in 50 years?

Not really.

DOT 4 is much better - but still needs to be changed from time to time.

DOT4 has a higher boiling point, dry, than DOT3 - which means it has a
higher boiling point for the same amount of moisture, too - so the risk
of boiling the fluid is lower. Still there, but lower.
DOT5 was silicone based, but is a ******* to bleed.
DOT5.1 is glycol again, higher boiling point still, but still only about
the same as LHM, and still hygroscopic.

'course, a higher boiling point doesn't mean moist fluid'll rot the
inside of the cylinders any slower.

Which is exactly why I've now got to replace the clutch hydraulics on the
Landy, despite having changed the fluid when I got it last year. Wet
fluid, rusted bores, leaky seals. All very predictable.

I had one, in that car I used for 40 years, a Golf. But that was because
I didn’t do anything about the known windscreen leak that would
produce a wet floor after heavy rain. Eventually that rusted thru
the floor and the brake line that runs down the inside corner of
the floor. That's why it was replaced by the Getz because
I couldn’t be arsed to replace the floor and the brake line.

sigh Just because the brakes didn't fail didn't mean that nothing's
going on. Have you, in 44 years, never compared the colour of fresh
brake fluid (light straw) to old fluid (varying shades of dark brown)?
Bearing in mind it's a non circulatory system and not being
contaminated, what do you think causes this?

You could easily use any liquid that takes your fancy as brake fluid;
they're all equally good at basic hydraulic operation. You might not
want to live in a hilly area or do much towing, but otherwise they'll be
fine.

That is the key, "normal" driving doesn't really give modern braking
systems a hard time. The problem is when the absorbed water gets down
to the cylinders and they get seriously hot and the water boils
forming compressible gas pockets releasing the pressure between pad
and disc.

Hands up those that have had the brakes on a modern car fade? I have
Ford Monedo, ventilated discs on the front. But that was after a very
"spirted" 1,100' descent in about 5 miles from Hartside Top to
Melmerby. A very nice road to "drive", with sharp 2nd gear bends,
straights, sweeping bends and sections where you can see what is (or
isn't) coming as you approach a bend.

It's bit unnerving approaching a 2nd gear bend at 60 mph, hit the
brakes, and something, followed rapidly by nothing, happens. Pressing
the pedal harder makes things worse. Once in that state it wouldn't
take much braking to fade them out again. The brakes didn't reliably
come back until I'd driven a mile or so without using them.

Apart from anything else, brake fluid should be replaced at two year

My Hyundai Getz says nothing like that, just INSPECT the brake fluid
every 2 years.

Well, yes, you can do that. Then you can be surprised when the hygrometer
tells you it IS due for replacement,

It doesnt tell you to use a hygrometer, it's just talking about
checking the level.

and you find that the bleed nipples
are all seized.

They weren't in the Golf that had never had the brake fluid changed
for 40 years. I tried to bleed the brakes when the brakes had clearly
failed and discovered that the problem was a failed metal brake line
when I could see the brake fluid coming out onto the concrete
driveway because I had not bothered to fix the known windscreen
leak which eventually rusted the floor and the brake line.

Still, on something where minimising service costs in the
short term is a higher priority for the manufacturer than long term
maintenance, it's not a great surprise that they'd recommend such penny-
pinching.

The dont do that with that engine and transmission oil, so that line can't
fly.

Perhaps brake fluid has improved over the years

No, the usual DOT 3/4/5.1 is still just as hygroscopic as it ever was.

Presumably they have enough of a clue to use brake cylinders that
handle brake fluid with some water in it fine and have decent seals too.

Nope. Lets say the van's only used very occasionally, for whatever

it would never ever have seen the inside of a workshop in all that time.

I have never ever changed the brake fluid on any of them, and guess what? I
have never had brake failure.


You have *never* had a cylinder seized owing to corrosion? I find that
hard to believe.

You probably haven't ever had to brake hard enough long enough to cause
any problems.

That is the key, "normal" driving doesn't really give modern braking
systems a hard time. The problem is when the absorbed water gets down
to the cylinders and they get seriously hot and the water boils
forming compressible gas pockets releasing the pressure between pad
and disc.

Hands up those that have had the brakes on a modern car fade?

I don't drive any car in a way that produces that result.

Not in any of the cars I have ever owned.

I have had brake failure in a 1960s landrover, but that was a
work vehicle so I didn’t find out what the problem was because
I didn’t fix it myself.

Come to think of it tho, with modern computer controlled
cars, it makes a lot more sense for the computer to keep
track of the number of starts and how warmed up the
engine got and tell you when to change the oil rather
than to just use a very crude do it every 2 years with
the cars that don’t make the miles required in 2 years.

It is a long time since I had a vehicle with a fixed service interval.
They all tell me when they think a service is due, based upon the type
of driving done.

I will say again that I have never had brake failure.

sigh Just because the brakes didn't fail didn't mean that nothing's
going on. Have you, in 44 years, never compared the colour of fresh brake
fluid (light straw) to old fluid (varying shades of dark brown)? Bearing
in mind it's a non circulatory system and not being contaminated, what do
you think causes this?

You could easily use any liquid that takes your fancy as brake fluid;
they're all equally good at basic hydraulic operation. You might not want
to live in a hilly area or do much towing, but otherwise they'll be fine.

sigh The brakes did not fail .............................. ffs!
Did you actually read my postings?
The ones where I mentioned that my taxis of 19 years were doing the best
part of 1000 miles per week?
The bit where in 44 years of diving I have never changed the fluid?
The bit where in 44 years of driving I have never had brake failure?

Obviously those who owned the car before you looked after their brakes.

No one owned the car before me with the last 3 of mine, they were all
bought new.

Does Holden still own your ****** stupid nation then?
All Australians are stupid.
I look around for products made in Australia. **** all to be found.
