V8v brake fluid
V8v brake fluid
I think we are supposed to change the brake fluid once every 2 years. I saw Redpants sell the Motul dot 5.1 but I have heard owners recommend Motul dot 4 RBF600. What is really the difference for everyday driving?
Also, how many 500 ml bottles do we need?

For every day driving, you won't notice a difference. The difference comes pretty much exclusively at the track--a higher boiling point allows you some cushion so that you don't boil the fluid and lose brake pressure. I use RBF600, and I track my car frequently. I have boiled the fluid once, but the fluid was a year old (and cars that are tracked frequently should flush the fluid more often than that), and it was on a very technical track more suited for lighter cars. So if you're not tracking your car multiple times a year while simultaneously neglecting the frequency with which you should flush the fluid, any of those options will be fine.
You'll need 1.5L total to flush the entire system, so that'd be three 500ml bottles.

Is the brake fluid reservoir the same as the clutch fluid reservoir? What is the service interval for changing the clutch fluid for the manual transmission cars? Does it use the same Motul dot5.1 brake fluid? How much do I need for the clutch?

I'll be taking my car for a clutch replacement soon so I just ordered three 500mL bottles from Amazon, which are currently $16.15 per bottle:

A common mistake is to fail to pull the old fluid from the drain line on the clutch when replacing the fluid in the brake lines. Always a best practice to bleed all 5 lines, starting with the longest line first.
I love my fill tank and syphon tanks for doing this job:

Makes it much easier and cleaner to do, especially if you are a one person shop.

please clarify... it's my understanding that in order to do a complete flush for brakes and clutch the Aston dealer had to run it on their software... something abour purging lines with AMDS...
I have ASM and have full flush scheduled with dealer in April... about $200 all in

If you don't let air get in (flushing the system doesn't require draining it first--just pushing new fluid through it to flush out the old fluid), you absolutely do not have to get any computer equipment involved.

If air gets into the ABS system, then it becomes a lot more complicated.

Hi MRCW...it is my understanding that on our ASM units the brakes use one fluid and the ASM unit uses another. Why they recommend using a dealer as his AMDS machine can open the clutch values
and close correctly after filling this different fuild...starts with a P...something. On Pistonheads one thread stated by Bradford Rose you can do yourself by cycling the paddle shifters with no harm but I leave this area to the professions as if you drain incorrect the gears lock up and the car must be towed.
There is a tank under the car in ASMs for filling with this different fuild. I believe the names and type are in our manuals and in the sticky section.
Save driving....

Hi Sliderule 01...wow that I did not know...
my only question does it cycle the ASM ECU too or only the brake area on the manual shift cars?
If it does the ASM separate from the brake area...you made me a happy man!!!
Even if not you gave me more reason to buy the foxwell unit...
Regards!!

You don't need any special tools to flush the brake fluid - either someone pumping the brake pedal or use a pressure bleeder.
The concern here is the clutch line:
On a manual car, flush it like the brakes by pumping the clutch pedal.
On a Sportshift/ASM/paddles car, obviously you can't pump the clutch pedal as there isn't one, so you're supposed to use an AMDS. I've heard of the method to do a Shortshift car yourself, but I won't try and I recommend against it as the consequence of it not working or if you do it wrong would mean having to flat-bed the car to a dealership as the transmission would be useless.
