Roughly how much brake fluid will it take to fill a 7 type car from scratch. Only reason I ask is trying to decide whether to buy 500ml or 1L of
Automec Silicone Brake fluid and it ain't cheap.
Thanks,
Matt
Bite the bullet and get a litre.You'll use it all up at some point.......
Normally under 0.5 litre, but I always buy a litre. its only about £4 anyway!
Do you definately want to use the silicon stuff? I haven't heard good reviews....
Dot5.1 - don't bother with the 'everlasting' synthetic stuff! Mineral is best!
Other than not dissolving your paintwork - I see no advantages is going for Silicone brake fluid.
I've heard that with little used vehicles, seals can become stuck in cylinders when using silicone.

If it's already had non-silicone in then be very careful as they aren't compatible and you may wreck every seal in the system.

interesting reading.....
silicon is non hydroscopic but 3 times as compressible.....
well I have run several cars on silicone brake fluid and I do quite like it.
It has several advantages other than not spoiling paintwork - which is a big advantage in itself.
the main one for me is it doesn't attract moisture which means that the braking system lasts longer because the internals don't end up
rusting and failing like it does with normal fluid which gradually deteriorates and is why the fluid needs changing in a normal car every couple of
years.
I've also used it on tracks and for hill climbing and not perceived any disadvantages in performance.
it is good for vehicles which stand unused for long periods of time like many of our vehicles do over winter.
As iank rightly says though it is totally incompatible with mineral fluid so only use it in a completely new system. if any of the components are
second hand then stick with mineral fluid.

Silicon is almost uncompressable, silicone on the other hand ...
Bizarrely never considered the difference!!!

I started off with silicone brake fluid - I would never use it again.
I never, ever, managed to get a good feel on the brake pedal - it always felt like it needed bleeding - apparently it is very easy to trap air in the
fluid when pouring it into the master cylinder. It can also cause corrosion, as it doesn't absorb water in the way that the conventional fluid
does, and can also lead to brake fade for the same reason - you can end up with water next to your brake pistons, which boils when the brakes get
hot.
Yes, ordinary fluid absorbs water, but that gets taken out of the system each time you change the fluid - you do change it every 2 years or so,
don't you?
BTW: It's a total PITA to change back to conventional fluid if you change your mind - it took me about 4 or 5 changes to get rid of it.

^^^^ wot he said plus if meory serves me well, it is less densetan water so if water does get into the system, it will be right at teh bottom, usually
the pistons to correode them plus being the hottest part, would boil the water first.
.... bit going off topic slightly, is there any data on how much water is absorbed into the brake fluid over time?
I mean, it isnot like the car is being used as a submarine so how much water vapour is in the air (UK climate) then how small is the breather hole in
the master clyinder and there is not much moveemnt of gas via that hole plus the rubber membrance seals to prevent the entry of water, make me wonder.
