Expert Installation & Field Note
Based on our shop experience specializing in heavy-duty brakes since 1985: The 1-1/8-inch bore is a staple in manual brake systems. Because this unit uses 1/8-27 NPT (National Pipe Thread) outlets, we recommend using a quality thread sealant to ensure a leak-free seal. Improper pushrod alignment is the leading cause of spongy pedal feel; ensure total linkage alignment to maximize cylinder life.
⚠ CRITICAL: Verify Specifications
To ensure safety, verify that this master cylinder’s 1-1/8-inch bore size and dual 1/8-27 NPT outlets match your existing unit before purchasing.
