OE 45670-4E030 — Piston Brake for Hyundai

Position depends on the platform. On most Hyundai applications the piston brake sits on the brake system 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.

Aftermarket piston brake comes from tooling houses that hold the original drawings or licensed equivalents. KingMay sources from vetted factories and inspects each batch; the manufacturer name is available on request where your market requires origin documentation.

For a short distance at reduced load, usually yes — but the risk compounds. A degraded piston brake transfers stress to neighbouring components, so a small repair can grow into a full brake system rebuild. Book the replacement once the symptom is repeatable.

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

Yes, if the alternate shares the same engineering envelope. Shortlist candidates from the Related OE References table, then check bolt pattern, electrical pinout and material grade. A difference in any of those three means it is a different part, not a substitute.

Standard minimum order is 10 pieces per part number. Mixed orders that combine 45670-4E030 with other brake system references are welcome — that is how most clients fill an LCL or FCL container without over-stocking a single line.
