BYOMC Kit – Bring Your Own Master Cylinder (M8 Softail & Touring)

08+ Touring fitment is available for preorder.

Already have your choice of 40mm mounting master cylinder? This kit has everything else to put it on your 2018+ M8 Softail, or 08+ Touring as a preorder.

Aftermarket parts: Kits are designed for stock bikes. Touring BYOMC only: the master cylinder sits about 1/4" (6mm) closer to the frame than stock and the brake line comes off a 90° fitting, so some aftermarket crash bars and engine guards (for example the IMZZ Elite) may need clearancing or may not fit. This doesn't apply to the Softail BYOMC. VTwin Envy isn't responsible for fitment with aftermarket or custom parts, so check your clearance before you order. Questions? Email vtwinenvy@agentmail.to.

Includes: laser-cut bracket, custom stainless pushrod, clevis + pin/clip, stainless mounting bolts, reservoir P-clamp, Tygon tubing, hose clamps, banjo bolt.

Titanium hardware is preorder: we order the bolts for your kit when you buy, which can add a little time before it ships. Titanium upgrade: Grade 5 hex flange bolts in your choice of 8 colors. Colored bolts can add a few extra days before your kit ships.

Bracket shown painted; Softail brackets ship raw so you can paint or powder coat to match. Test-fit before painting, because painted or coated parts can't be returned.

Only the master cylinder is not included. Reservoir, hose, clamps and banjo bolt are included.

Install directions are emailed with your order. You have to reverse bleed on install with fresh DOT 4. Banjo bolt torque 15 ft-lb (20 N·m).

Pairs great with: no master yet? The complete kits include the Brembo master: M8 Softail kit or 08+ Touring kit. For the front: the Brembo RCS radial front master (Single disc = RCS15, Dual disc = RCS19).

Safety: brake parts are safety-critical. We recommend professional installation. Bleed the system and confirm the brake works before riding. VTwin Envy is not affiliated with or endorsed by Harley-Davidson or Brembo; names are used for fitment reference only.
