Project Mu's G-Four 335 brake fluid features an innovative maintenance indicator that simplifies fluid monitoring. The fluid starts green when fresh, and as it degrades from heat cycling and moisture absorption, it gradually turns crystal clear—providing a visual cue that it's time for replacement. This unique feature eliminates guesswork and ensures optimal braking performance during demanding driving conditions. Do not mix with other brake fluids; complete system flush recommended prior to use.
