The OLA Master Cylinder is a brake master cylinder assembly designed specifically for use on OLA electric scooters such as the OLA S1 and S1 Pro (Gen 1 & Gen 2). It’s an essential part of the scooter’s hydraulic braking system, converting the mechanical pressure applied by the rider on the brake lever into hydraulic pressure that actuates the brake caliper, enabling effective stopping power. These assemblies often include the master cylinder body, integrated reservoir, brake lever, and in some versions a brake light/safety switch.

• Precisely converts your lever pull into hydraulic fluid pressure for reliable, smooth braking response on both front and rear brakes (depending on left/right assembly).
• Engineered to be a direct replacement for original OLA scooter master cylinders — no modification required.
• Many assemblies include a pre-installed brake lever and sometimes a brake light switch, simplifying installation and enhancing safety.
• Designed for straightforward fitting onto standard OLA scooter handlebar mounts with basic tools.
