OE 59110-4M000 — Brake booster assembly for Hyundai / Kia

Treat it as a wear item: inspect every 20,000-30,000 km and replace at the first sign of leakage, noise or performance loss. Real service life swings widely with climate, road surface and duty cycle, so mileage on its own is a weak indicator.

Standard minimum order is 10 pieces per part number. Mixed orders that combine 59110-4M000 with other suspension, steering & brake references are welcome — that is how most clients fill an LCL or FCL container without over-stocking a single line.

Incoming batches pass a dimensional check, a material look-up against the suspension, steering & brake specification, and a visual inspection for finish defects. Critical dimensions are measured per carton and the photographs are archived against the order number.

Bulk pricing is tiered: 10 pieces, 50 pieces and full-carton quantities each carry a different unit rate. Piece price also moves with packing format and whether your own brand is printed on the carton, so tell us the landed quantity you are planning.

Position depends on the platform. On most Hyundai / Kia applications the brake booster assembly sits on the suspension, steering & brake assembly and can be reached from the engine bay or the underbody without removing the dashboard. Torque figures and disassembly order are given in the workshop manual for each model.

The Related OE References table above lists the alternates we see most often in trade inquiries. Cross-references work because the engineering envelope is shared across the suspension, steering & brake family — always confirm dimensions and connector layout before you swap.
