FAQs

How do I know which size master cylinder to choose?
Typically the 5/8 master cylinder is proven on an S/R/Z chassis running the single or two pot brakes, the lever feel with this master is balanced, having a longer more typical throw to gauge feel while still efficiently locking the rear brakes.

The 3/4 master cylinder is larger, so when used in that same setup the lever feel will be more direct, firmer, and require less throw to lock the rear brakes. However, if you are running larger brakes/wheel tire setup then the standard two pot and 235 width tire and do require a bit more bite, we would suggest this master cylinder.

Do FLUX Master Cylinders have warranty?
Yes! All FLUX master cylinders have lifetime warranty.

Are FLUX Master Cylinders rebuildable?
Yes! Rebuild kits are available to ensure low cost and easy maintenance on all master cylinders.

Do you offer other masters?
We offer a wide range of FLUX masters to suit 3/4", 5/8", 7/8" applications, available in both integral and inline reservoir variants.Β 

What type of flare do the FLUX master cylinders have?
They have a SAE 45 degree flare which will work with both an inverted flare (single) and a double flare.
