GeoBrakes stocks disc brake caliper kits confirmed to fit the Bmw X4, pairing a replacement caliper at the correct left or right hand specification for the X4 with matched brake pads, caliper hardware, and in many cases a new rotor, so the entire brake corner on your Bmw X4 is restored in a single service. Every kit is confirmed for the Bmw X4 exact year, make, model, axle, and side, ships with a 100% fitment guarantee and full manufacturer warranty, and qualifies for free delivery on orders over $99.
When a caliper on the Bmw X4 seizes, leaks, or drags, the damage does not stop at the caliper. A partially seized caliper on your X4 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 X4 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 X4 together.
The kit for your Bmw X4 includes the disc brake caliper at the correct left or right hand specification for the X4, either new OEM-spec or quality remanufactured to the Bmw X4 piston dimension and hydraulic pressure rating, brake pads in ceramic or semi-metallic formulation matched to the X4 caliper and rotor specification, caliper hardware with slide pins, pin boots, and anti-rattle clips for correct caliper float on the Bmw X4, brake lubricant for correct pin and shim installation on your X4, and copper washers or banjo bolt seals for the brake hose connection where required by the Bmw X4 application.
A caliper kit is the right call for the Bmw X4 in three specific situations. After a seized or dragging caliper, because the pads and often the rotor on your X4 are already compromised. During a high-mileage X4 overhaul at 150,000 kilometres or more, because caliper piston seals and guide pin boots on the Bmw X4 are typically at or beyond their service life. After a brake fluid leak at the caliper, because fluid contamination of the X4 brake pad renders the friction material permanently ineffective on your Bmw X4.
New OEM-specification calipers for the Bmw X4 are manufactured from fresh materials with no prior service history, the strongest choice for X4 vehicles in high-corrosion environments. Remanufactured calipers use original Bmw X4 housings rebuilt with new pistons, seals, and boots, performing identically to new units at a lower price point for most X4 replacement applications.
Calipers for the Bmw X4 are the most position-specific brake component in the catalogue. Left and right calipers for the X4 are not interchangeable. Our vehicle selector confirms the correct caliper kit for the Bmw X4 exact year, axle position, and left or right side before purchase.
Should I replace both calipers on my Bmw X4 at the same time?
It is strongly recommended. If one caliper on the Bmw X4 has seized or leaked, the caliper on the opposite side has experienced the same conditions and age on your X4. Replacing both restores balanced, even braking and eliminates the risk of the second X4 caliper failing shortly after the first is replaced.
Do I need to bleed the brakes on my Bmw X4 after installing a caliper kit?
Yes. Opening the hydraulic circuit on the Bmw X4 to install the new caliper allows air to enter. After installation, the brake circuit on the X4 must be bled at the caliper bleeder screw to purge all air and restore a firm, consistent brake pedal on your Bmw X4.
What is the difference between a new and remanufactured caliper in the Bmw X4 kit?
A new caliper for the Bmw X4 has no prior service history and is the stronger choice for high-corrosion environments. A remanufactured caliper uses an original X4 housing rebuilt with new pistons, seals, and boots, performing identically to new at a lower price point for most Bmw X4 applications.
