All Endless products →Questions about this kit
Will this fit my wheels?
Big brake kits need clearance between the caliper and the wheel barrel and spokes. Check the minimum wheel size in the specifications and send us your wheel model if you are unsure — we will confirm with a clearance template.
Do I need new brake lines or fluid?
Every kit includes braided lines and the hardware listed under What's in the box. We recommend fresh DOT 4 fluid and a full bleed after installation.
Can I install this myself?
Installation requires torque tools, a bleed procedure and a bed-in cycle. We recommend professional installation; our installation support page lists torque specs and bed-in steps.
