When a caliper on the Bmw 430i seizes, leaks, or drags, the damage does not stop at the caliper. A partially seized caliper on your 430i keeps the brake pad in continuous contact with the rotor, wearing the pad unevenly and scoring the rotor surface. By the time the caliper on the Bmw 430i is identified as the fault, the pads are typically worn asymmetrically and the rotor is damaged. A caliper kit from GeoBrakes addresses every compromised component on your Bmw 430i together.
The kit for your Bmw 430i includes the disc brake caliper at the correct left or right hand specification for the 430i, either new OEM-spec or quality remanufactured to the Bmw 430i piston dimension and hydraulic pressure rating, brake pads in ceramic or semi-metallic formulation matched to the 430i caliper and rotor specification, caliper hardware with slide pins, pin boots, and anti-rattle clips for correct caliper float on the Bmw 430i, brake lubricant for correct pin and shim installation on your 430i, and copper washers or banjo bolt seals for the brake hose connection where required by the Bmw 430i application.
A caliper kit is the right call for the Bmw 430i in three specific situations. After a seized or dragging caliper, because the pads and often the rotor on your 430i are already compromised. During a high-mileage 430i overhaul at 150,000 kilometres or more, because caliper piston seals and guide pin boots on the Bmw 430i are typically at or beyond their service life. After a brake fluid leak at the caliper, because fluid contamination of the 430i brake pad renders the friction material permanently ineffective on your Bmw 430i.
New OEM-specification calipers for the Bmw 430i are manufactured from fresh materials with no prior service history, the strongest choice for 430i vehicles in high-corrosion environments. Remanufactured calipers use original Bmw 430i housings rebuilt with new pistons, seals, and boots, performing identically to new units at a lower price point for most 430i replacement applications.
Calipers for the Bmw 430i are the most position-specific brake component in the catalogue. Left and right calipers for the 430i are not interchangeable. Our vehicle selector confirms the correct caliper kit for the Bmw 430i exact year, axle position, and left or right side before purchase.
Should I replace both calipers on my Bmw 430i at the same time?
It is strongly recommended. If one caliper on the Bmw 430i has seized or leaked, the caliper on the opposite side has experienced the same conditions and age on your 430i. Replacing both restores balanced, even braking and eliminates the risk of the second 430i caliper failing shortly after the first is replaced.
Do I need to bleed the brakes on my Bmw 430i after installing a caliper kit?
Yes. Opening the hydraulic circuit on the Bmw 430i to install the new caliper allows air to enter. After installation, the brake circuit on the 430i must be bled at the caliper bleeder screw to purge all air and restore a firm, consistent brake pedal on your Bmw 430i.
What is the difference between a new and remanufactured caliper in the Bmw 430i kit?
A new caliper for the Bmw 430i has no prior service history and is the stronger choice for high-corrosion environments. A remanufactured caliper uses an original 430i housing rebuilt with new pistons, seals, and boots, performing identically to new at a lower price point for most Bmw 430i applications.
