Performance Brake Fluid?

[BimmerRob08]

Ok, wanted to make a new thread about brake fluid so to get everyones inputs.

I'm planning on going with CoolCarbon pads, OEM rotors for now, Brake lines and fluid.

Big question as I don't know much about the fluid. I still want to be able to retain the warrenty on the brake system so I need a performance fluid for street/light track use that BMW won't freak out about and void my warrenty on the brake system. What do you guys suggest? Thanks for the help.

cheers

I have been using RBF 600 for many years with great results.
There are a lot of good fluids out there, Castrol SRF, AP Racing PRF, ATE. Don't use the ATE Super Blue, I personally like how it stains your brake system.

I'm running stock as far as my brakes go. But I drive hard and I'm getting new pads installed soon. Is the <Motul RBF600> oil something that I need?

Any DOT 4 fluid should work as far as warranty and street use, but the higher dry and wet boiling point of the RBF600 meets all practical needs. Be advised that some brake fluids such as Castrol SRF and some AP fluids can not be mixed with other brake fluids so you need to do a complete system flush - which is a good idea any way for track use so that you don't have old and new fluid in the system.

Agreed 100%, Motul 600 should fit anyone's needs on the street and with moderate track useage.

ATE Gold/Blue uses different dyes (depending on change interval) to confirm fluid flushes and is perfectly fine for the street.

We use either Motul RBF 600 or ATE super blue 90% of the time. On the Race car we tend to use Motul when possible. We have used ATE as well in some racing applications with great results.

Seems like when we use the ATE blue in any of the japanese cars, the blue dye never stays in the system at least. we have a number of customers cars we do that swap blue/gold here all the time as the flush the full system.

Has anyone used the Motul 660? Seems superior to the 600 but no one has mentioned it. Is it for a different application maybe? Any downsides as opposted to the 600? Is it also for street use?

Motul 660 has a higher dry boiling point but a lower wet boiling point compared to Motul 600

Thanks guys!

No love for Castro SRF? It' has the highest dry boiling point, which is the important number. It's more money but comes in a larger bottle and you don't need to change it as much given the wet boiling point.

Also, is the Motul 600 really that much better than the ATE? The dry/wet boiling points are almost the same, while the Motul is considerably more money when you consider it's in 500cc bottles and the ATE in 1L bottles.

If I want to change my brake fluid how much of the Motul 600 do I need?

The ATE is fine for many people but the Motul and Castrol SRF are both superior for wet and dry boil temps.

Is that difference in wet/dry boiling point significant between the Motul600 and ATE in real word driving?

I just think it doesn't warrant the considerable price difference. I'd rather get the Castro since it's significantly better on both accounts to the ATE. Just my thinking, but please correct me if I'm off base.

Looks like the stock fluid is ATE, but may have different (worse) specs): http://www.m3post.com/forums/showpos...22&postcount=3
