Expert Installation & Field Note
Based on our shop experience specializing in heavy-duty brakes since 1985: This 1-3/4-inch bore master cylinder is a primary component of larger power clusters. When installing the M170125, ensure the pushrod is perfectly aligned with the cluster chamber. Even slight pushrod misalignment can cause excessive wear on the remanufactured seals. Note that a $50.00 core refund is available for your rebuildable core; please allow 2-3 months for core eligibility verification and processing.
⚠ CRITICAL: Verify Specifications
To ensure safety, verify that this master cylinder’s 1-3/4-inch bore size and residual check valve configuration match your cluster requirements exactly. Using a non-residual valve unit where one is required will result in poor pedal response.
