Technical Specifications

Installation Overview

1. Preparation: Safely lift the vehicle and secure it on jack stands. Drain the brake fluid reservoir to prevent spills during removal.
2. Removal: Disconnect the hydraulic line from the existing cylinder, remove the mounting bolts, and carefully extract the old cylinder.
3. Installation: Position the new BWD318 cylinder onto the mounting flange. Tighten the bolts to the manufacturer’s torque specification (typically 35–40 ft‑lb).
4. Reconnection: Reattach the hydraulic line, ensuring a snug fit with a rubber gasket.
5. Bleeding: Bleed the brake system according to Mazda’s procedure to eliminate air pockets and restore full pedal pressure.

Maintenance Tips

• Inspect the cylinder seal for signs of wear or cracking every 12,000 miles (or as recommended by your vehicle’s service schedule).
• Keep the hydraulic lines clean and free from debris to prevent contamination.
• Use only manufacturer‑approved brake fluid to maintain optimal performance and avoid corrosion.
