Expert Installation & Field Note

Based on our shop experience specializing in heavy-duty brakes and clutches since 1985: Hydraulic clutch performance relies on a clean, sealed system. Air trapped in the slave cylinder is the #1 cause of incomplete clutch release. We recommend gravity bleeding followed by a standard pressure bleed to ensure all air is purged from the 29/32-inch bore size chamber. Always inspect your master cylinder and hydraulic lines for contamination; old fluid can quickly damage a new slave cylinder’s seals. Bleed thoroughly with fresh, approved fluid to guarantee maximum lifespan.

⚠ CRITICAL: Verify Specifications

To ensure safety and proper clutch travel, verify that this slave cylinder’s 29/32-inch bore size and 7/16-24 mounting configuration match your existing unit exactly. This component is designed exclusively for hydraulic clutch systems; it is not a universal fitment.
