J.C. Whitney SET-JB27150005 Front Brake Caliper 2-Wheel Set OEM Replacement

The J.C. Whitney SET-JB27150005 is a front brake caliper kit that includes two OEM-replacement brake calipers engineered as direct-fit replacements for the BMW X3 E83 (2004–2011). This set restores proper braking function with components designed to match the original equipment specifications, delivering reliable stopping power and long service life.

Key Features:

• Complete 2-Wheel Set: Includes two (2) front brake calipers — driver side and passenger side — covering both front corners in a single purchase
• OEM Replacement Design: Engineered to match original factory specifications for a direct bolt-on installation with no modifications required
• Corrosion-Resistant Finish: Calipers feature a protective coating to resist rust and extend service life
• Steel Pistons: Single-piston design per caliper with steel piston construction for durability and consistent brake performance
• Brake Line Compatibility: M10 x 1.0 inlet port and M8 x 1.25 bleeder port sizing consistent with BMW E83 X3 brake system specifications

Replacing worn or seized brake calipers is essential for maintaining safe, even braking. This set is ideal for restoring pedal feel and eliminating symptoms such as pulling, uneven pad wear, or reduced stopping power. Installation follows standard BMW front caliper replacement procedures — raise and support the vehicle, remove the wheel, disconnect the brake line and sensor harness, unbolt the caliper bracket from the steering knuckle, and bleed the brake system upon completion.
