Expert Installation & Field Note
Based on our shop experience specializing in heavy-duty brakes since 1985: The 1-1/8-inch bore is sensitive to internal bypass if seals are worn, especially in vehicles carrying heavy loads. During installation of the M172241, verify that the entire hydraulic system is in good condition. Improper pushrod alignment is the leading cause of spongy pedal feel; ensure total linkage alignment to prevent side-loading and maximize cylinder life.
⚠ CRITICAL: Verify Specifications
To ensure safety, verify that this master cylinder’s 1-1/8-inch bore size and 1/2-20 INV outlet match your existing unit before purchasing.
