GeoBrakes stocks disc brake caliper kits confirmed to fit the Bmw X3, pairing a replacement caliper at the correct left or right hand specification for the X3 with matched brake pads, caliper hardware, and in many cases a new rotor, so the entire brake corner on your Bmw X3 is restored in a single service. Every kit is confirmed for the Bmw X3 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 X3 seizes, leaks, or drags, the damage does not stop at the caliper. A partially seized caliper on your X3 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 X3 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 X3 together.
The kit for your Bmw X3 includes the disc brake caliper at the correct left or right hand specification for the X3, either new OEM-spec or quality remanufactured to the Bmw X3 piston dimension and hydraulic pressure rating, brake pads in ceramic or semi-metallic formulation matched to the X3 caliper and rotor specification, caliper hardware with slide pins, pin boots, and anti-rattle clips for correct caliper float on the Bmw X3, brake lubricant for correct pin and shim installation on your X3, and copper washers or banjo bolt seals for the brake hose connection where required by the Bmw X3 application.
A caliper kit is the right call for the Bmw X3 in three specific situations. After a seized or dragging caliper, because the pads and often the rotor on your X3 are already compromised. During a high-mileage X3 overhaul at 150,000 kilometres or more, because caliper piston seals and guide pin boots on the Bmw X3 are typically at or beyond their service life. After a brake fluid leak at the caliper, because fluid contamination of the X3 brake pad renders the friction material permanently ineffective on your Bmw X3.
New OEM-specification calipers for the Bmw X3 are manufactured from fresh materials with no prior service history, the strongest choice for X3 vehicles in high-corrosion environments. Remanufactured calipers use original Bmw X3 housings rebuilt with new pistons, seals, and boots, performing identically to new units at a lower price point for most X3 replacement applications.
Calipers for the Bmw X3 are the most position-specific brake component in the catalogue. Left and right calipers for the X3 are not interchangeable. Our vehicle selector confirms the correct caliper kit for the Bmw X3 exact year, axle position, and left or right side before purchase.
Should I replace both calipers on my Bmw X3 at the same time?
It is strongly recommended. If one caliper on the Bmw X3 has seized or leaked, the caliper on the opposite side has experienced the same conditions and age on your X3. Replacing both restores balanced, even braking and eliminates the risk of the second X3 caliper failing shortly after the first is replaced.
Do I need to bleed the brakes on my Bmw X3 after installing a caliper kit?
Yes. Opening the hydraulic circuit on the Bmw X3 to install the new caliper allows air to enter. After installation, the brake circuit on the X3 must be bled at the caliper bleeder screw to purge all air and restore a firm, consistent brake pedal on your Bmw X3.
What is the difference between a new and remanufactured caliper in the Bmw X3 kit?
A new caliper for the Bmw X3 has no prior service history and is the stronger choice for high-corrosion environments. A remanufactured caliper uses an original X3 housing rebuilt with new pistons, seals, and boots, performing identically to new at a lower price point for most Bmw X3 applications.
