Rear Brake Master Cylinder for Honda ATC-250R 1982 200x Bike

This rear brake master cylinder is a direct-fit replacement hydraulic component built for Honda ATC-250R and 200x three-wheeler models, converting lever pressure into reliable braking force at the rear wheel.

Overview

This rear brake master cylinder for Honda ATC-250R and 200x bikes restores proper hydraulic pressure to the rear braking system so the caliper engages smoothly and predictably. It is designed for riders maintaining or rebuilding older three-wheeler braking systems where the original master cylinder has worn seals, corroded bores, or lost fluid pressure. The unit installs in the stock location and connects to existing brake lines and levers for a straightforward replacement.

Specs At A Glance

Good To Know

Q: Do I need to bleed the system after installing this rear brake master cylinder? A: Yes, air must be bled from the brake line and caliper after installation to restore firm lever feel. Use fresh DOT brake fluid and bleed until no bubbles appear.

Q: Will this fit both the ATC-250R and the 200x? A: It is listed for both models, but mounting and line routing can vary by year and serial number. Confirm your machine's fitment before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
