The aluminum body, 0.875-inch bore, integrated reservoir, and included sensor are specified to match the original hydraulic setup on the listed vehicles.

• Low or inconsistent brake pedal feel
• Brake fluid leakage at the master cylinder
• Warning light concerns related to the brake hydraulic system

Installation Notes

Verify the vehicle’s stability control configuration before ordering, since fitment is limited to the listed Suzuki SX4 and SX4 Crossover applications. Confirm the outlet thread size, reservoir layout, and sensor connection against the original unit before installation. Brake system bleeding is required after replacement, and the hydraulic system should be inspected for leaks and proper pedal operation once installed.
