Brake Fluid Recommendation
Hey all,
Just seeing what brake fluids people are running. Any feedback (positive and negative) will be most appreciated, as I am quite n00b on the subject. I'm looking at something that will withstand good abuse at the track. However, is it better to just use a factory fluid and change more often, or go to the expense of a better fluid? Cheers, John |

Castrol SRF
Extreme performance, silicon ester based brake fluid with a very high boiling point. Formulated for use in drum and disc brakes in competitive motorsport, including motorcycles, rallying, touring and Formula 1. Not for use in systems where a mineral oil is specified. :D :D |
Thanks Broomy.
[QUOTE=mr_psi]Dot4[/QUOTE] I'm after a bit more info than just 'Dot 4'. I'm looking at specific brands people have used, dry boiling point, wet boiling points, how hygroscopic they are etc. |
I use Elf Racing, working well so far.

Boiling Point °C 260 Equilibrium reflux boiling point °C290 Vapor lock protection °C250 Vapor lock protection with 3.5% water 200 Wet equilibrium reflux boiling point °C 190 – 200 Auto ignition temperature °C> 300 Density at 20°C kg/m³ 1065 100°C visvosity mm²/s 1.5 min -40°C viscosity cSt 1500 max Miscible with all DOT fluids. Not miscible with silicone or silicate esters fluids. Seals to be used: any classical brake system seals (respect FMVS Nr. 116 U.S. limits for seals). Corrosion and compatibility: no specific limitation (exceed all DOT4 stand Nr. 116 specifications). Safety and transport information: classified as not dangerous fluid. |
I used elf in the old car and it was great. I am using AP in this one and it too has been great.
I am definately upgrading to braided brake hoses to get even better pedal feel. brendon |
I put in some Castrol Super Response or something along those lines. Dot 4 fluid. Got it for under $10 for 500ml.
Im happy with it for just a road car. Theres another Castrol Dot 4 fluid in a red bottle. But its not as good apparently. for a couple buck more the silver bottle castrol fluid seems to do the job very well. |

For sustained track work i really can't comment but i haven't had any fade or boiling issues from heavy street use and motorkhanas, although i do bleed the system before events. |
Castrol Super Response Dot 4.1. (Silver Bottle)
No boiling/fade even after a hammering on the track (GC8 WRX) in conjunction with DBA 4000 discs and Ferodo DS2500 Pads. Good stuff. J |
