Surron Ultra Bee Foot Brake Master Cylinder FAQ
Will it fit my Ultra Bee foot brake?
Yes. It fits all Surron Ultra Bee foot brakes. It is the same HSK master cylinder that comes in our Ultra Bee foot brake kit.
Why won't the cheaper HSK master cylinder fit my Ultra Bee?
The mounting holes are different and the pushrod is shorter. That one is built for Light Bee, Talaria, and Eride Pro foot brakes: Surron Foot Brake Master Cylinder HSK. This one is Ultra Bee only.
Does it come filled and bled?
No. It ships dry. Bolt it on, connect the line, then fill and bleed before you ride. Our bleed kit with check valve handles it.
What brake fluid does it take?
DOT 3, DOT 4, or DOT 5.1. We bleed our kits with Motul DOT 5.1.
Is this the handlebar brake master cylinder?
No. This is foot brake only. For the hand levers, the left side takes the Surron Ultra Bee Rear Master Cylinder and the right side takes the Surron Ultra Bee Master Cylinder Front.
Do I need any other parts?
The banjo bolt and both crush washers are in the box. If your clevis pin or cotter pin is worn or missing, grab the clevis pin and cotter pin set. Want titanium at the line? Our M10 x 1.25 titanium banjo bolts thread straight in.
