Brake Fluid Thread

[vtml]

I have used Motul DOT 4, $14 per 500ml from Autobarn. It doesn't cost an arm and a leg and it's pretty good. I bleed the brakes with that on the day before Phillip Island, no fade on the brake lines and I did not bother bleed them again until the next service/track day.

Price you pay I guess, I've never had a problem with SRF and I've used it for years. It's changed fairly regulary though...

How often would it need changing?

I would highly recommend you to take your car to a good mechanic that you trust if you decide to switch to Castrol SRF for the first time unless you are very confident in knowing what you are doing.

1) I would never use any silicon based brake fluid (SRF, Dot 5, etc) in a braking system thats used your typical Glycol based fluids, most used seals do not take kindly to silicon.

2) Unless you've got a hardcore trackcar, and you go through a set of brake pads a session, you're almost never going to need things like SRF or true up racing brake fluids.

3) RBF600 is abit of overkill for trackday cars but as its not comparitively expensive, knock yourself out. Although note that it will have a higher frequency of change. This RBF is similar to your HKS/Trust/whatever racing brake fluid...i.e. they are all Dot 4, Dot 5.1

4) In most cases, fresh Dot 4 (Castrol Ultra?) is more than enough...If you're boiling the fluids, you either have a mechanical fault (From as simple as not bleeding properly) or you need to improve your driving technique.
