Dear All,
I've just replaced almost the entire braking system on my Herald:
calipers, wheel and master cylinders, hoses and some pipework. Now
would therefore be a good time to change to silicone brake fluid, if
I'm going to do it.
What do you all think? Worthwhile for a car which will be doing light
summer duty only?
Ian
One minor advantage if you're as clumsy as I am - it doesn't take the
paint off when you spill it.

And if you wash it off straight away it dosen't take the paint either. |

Can we count that as a happy ending then?
Having followed your link on the item, I see what you mean that they
look useful and would have been tempted myself if they actually worked. |

I don't think so. Just change the ordinary stuff every two years and
you'll not have any corrosion problems. And a better pedal feel.
I when through that exercise and found the same thing. Not worth the
effort or cost.
Flushing it on a regular basis keeps the system in good order. My MG
has light use about 2000mls/year and have no problems. The whole system
was overhauled about 8 years a go. The caliper pistons were replaced
with stainless steel, rear cylinders resleeved stainless and the M/C
resleeved stainless. The only problem is the sludge and film buildup
within the system which needs cleaning. So the next step will be at 10
years to replace all the rubbers again as a regular maintenance item.
Regular maintenance is something that's neglected. Trying to step around
it by using silicon fluid is not the answer.
|
There is a temptation after, say, a complete brake overhaul to want to use
a fluid that will make things last for ever - but in practice the original
system could already have lasted 20 years plus if looked after. With drum
brakes they'll need a clean out every once in a while so a fluid change at
the same time ain't that much of a chore if you have a pressure bleeder.
Also a good time to inspect the hoses etc for damage. So aiming for
maintenance free isn't necessarily a good idea.

I'd have said so. No chance for the moisture to settle into the fluid and
just sit, gently rusting, over the winter.
I've heard the opposite argument, though - that normal brake fluid
absorbs and dilutes and moisture, whereas silicone stuff just leaves
it there to do its worst ...
|
The BIG difference is that silicone fluid isn't hygroscopic, like normal
brake fluid. Therefore, there's no reason for moisture to get into the
system in the first place.
