The YZ250F-spec master cylinder is a proven upgrade for your Surron Light Bee foot brake setup. It delivers stronger, more consistent pedal feel than the stock unit and drops in without drama.
Note: MUST BE USED WITH OUR FOOT BRAKE — other brands may require modifications to fit.
Install: Easy, 15–30 minutes. Tools: 8 and 10mm sockets, open end wrench, Allen keys, needle nose pliers, DOT 4 fluid, rags. 1) Put the bike on a stand and clean around the master and line. 2) Remove the pedal clevis pin and unbolt the stock master from the mount. 3) Move the brake line to the new master and bolt the new unit in place. 4) Reattach the clevis, top off with DOT 4, and bleed the rear circuit until firm. Bed in the brake with a few slow-to-fast stops to seat the pads. Tighten banjo bolts and mounting hardware to manufacturer spec. Do not ride until the pedal is firm and the system shows no leaks.
