Comparison of the various racing brake fluids we have in stock
Motul RBF660, Motul RBF700, Project MU G-Four 335, Castrol SRF
1L sufficient for brake flush on most vehicles
In our opinion the Castrol SRF remains the gold standard with its incredible WET boiling point, perfect for seasoned track veterans. For those that only plan on running 2 or 3 events a year however, the other options may make more sense.
*note Motul RBF is sold in 500ml bottles, price is for 2 bottles
