b'Racing Brake Fluid Brake Fluid Choices: Picking your brake fluid is more important than most choices, because brake fluids vary so much in real life performance & some dont mix with other brands.The most important performance factors are Dry Boiling Point (pure, right out of a sealed bottle, with no moisture) & Wet Boiling Point (with 3% moisture from condensation). Compatibility with other fluids matters, in case you find need to mix brands. Most professional race teams choose Castrol SRF, Endless RF-650, AP660, Motul 660, 700, StopTech 660 or Wilwood XR. Wilwoods XR polyglycol-ether-based brake fluid, has the highest dry rated boiling point. Castrol the highest wet boiling point. For my race teams, wed choose fluids based on observed caliper tempsthen inspect the fluid & bleed the brakes after every event. We would flush the lines with new fluid & bleed every 3 short events or 1 long event. Knowing you need to flush your brake fluid often, you may want to spend less. Running a brake fluid recirculatory system extends the life of your brake fluid & is self bleeding. If you race/run in wet, rainy or humid conditions, as we all do at some point, wet boiling point is very important, as the fluid will absorb moisture, even in your closed system. For budget Track-Warriors Ron recommends Motul 600/StopTech 600. With its high wet boiling point, it needs to be bled less often, saving you money. For more competitive Track-Warriors & budget Race-Warriors, Wilwood EXP 600, Motul 660, StopTech 660 & AP R3 are perfect. For Race-Warriors, go with Castrol SRF or Wilwood XR.Brake Fluid Performance Comparison List Brand DOT Rating Dry Boiling Wet BoilingCompatible Cost per Oz AP Racing R1DOT 3 550F (284C) 284F (140C) Yes$1.07 AP Racing R2DOT 4594F (312C)399F (204C)Yes$1.41 AP Racing R3 DOT 4 608F (300C) 399F (204C) Yes$1.78 AP Racing R4DOT 4 644F (325C) 399F (204C) Yes$2.75 ATE Super BlueDOT 4 536F (280C) 382F (194C) Yes ATE Super 200 DOT 4 536F (280C) 382F (194C) Yes$1.18 Bosch DOT 4 DOT 4 509F (265C) 329F (165C) Yes Bosch DOT 4 + DOT 4 536F (280C) 356F (180C) Yes Brembo LCF 600+ DOT 4 601F (316C) 399F (204C) Yes$1.60 Castrol GT LMA DOT 4 446F (230C) 311F (155C) Yes Castrol SRF DOT 4 590F (310C) 518F (270C) Yes$2.07 Endless RF-650DOT4613F (323C)424F (218C)Yes$2.66 Ford HDC6AZ-19542-AB DOT 3 550F (284C) 284F (140C) Yes Motul DOT 5.1 DOT 4 509F (265C) 365F (185C) Yes Motul RBF 600 DOT 4 594F (312C) 421F (216C) Yes$1.18 Motul RBF 660 DOT 4 617F (325C) 399F (204C) Yes$1.78 Motul RBF 700 DOT 4 637F (336C) 401F (205C) Yes$2.19 Performance Friction Z-RatedDOT 3 550F (287C) 284F (140C) Yes StopTech 600 DOT 4 594F (312C) 421F (216C) Yes$1.36 StopTech 660 DOT 4 617F (325C) 399F (204C) Yes$1.78 US Brake/AFCO 570 GoldDOT 3572F (300C) 284F (140C) Yes US Brake/AFCO Ultra HTXDOT 4 572F (300C)421F (216C) Yes$1.54 Valvoline ProSyn DOT 3/4 502F (261C) 343F (173C) Yes Wilwood 570 DOT 3 573F (300C) 313F (156C) Yes$1.42 Wilwood EXP600 Plus DOT 4 626F (329C) 417F (213C) Yes$1.60 Wilwood XR Race FluidNo Rating645F (341C)432F (222C)No$3.67667'
