Bmw 328i Disc Brake Caliper Kit in US

When a caliper on the Bmw 328i seizes, leaks, or drags, the damage does not stop at the caliper. A partially seized caliper on your 328i 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 328i 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 328i together.

What Is Included in the Bmw 328i Disc Brake Caliper Kit

The kit for your Bmw 328i includes the disc brake caliper at the correct left or right hand specification for the 328i, either new OEM-spec or quality remanufactured to the Bmw 328i piston dimension and hydraulic pressure rating, brake pads in ceramic or semi-metallic formulation matched to the 328i caliper and rotor specification, caliper hardware with slide pins, pin boots, and anti-rattle clips for correct caliper float on the Bmw 328i, brake lubricant for correct pin and shim installation on your 328i, and copper washers or banjo bolt seals for the brake hose connection where required by the Bmw 328i application.

When a Caliper Kit Is the Correct Service Choice for the Bmw 328i

A caliper kit is the right call for the Bmw 328i in three specific situations. After a seized or dragging caliper, because the pads and often the rotor on your 328i are already compromised. During a high-mileage 328i overhaul at 150,000 kilometres or more, because caliper piston seals and guide pin boots on the Bmw 328i are typically at or beyond their service life. After a brake fluid leak at the caliper, because fluid contamination of the 328i brake pad renders the friction material permanently ineffective on your Bmw 328i.

New vs. Remanufactured Caliper for the Bmw 328i

New OEM-specification calipers for the Bmw 328i are manufactured from fresh materials with no prior service history, the strongest choice for 328i vehicles in high-corrosion environments. Remanufactured calipers use original Bmw 328i housings rebuilt with new pistons, seals, and boots, performing identically to new units at a lower price point for most 328i replacement applications.

Signs the Caliper Kit on Your Bmw 328i Is Due

• Bmw 328i pulling to one side during braking, one caliper applying more force than the other
• One brake pad on your 328i worn significantly more than its pair on the same axle
• Brake drag on the Bmw 328i with a wheel that runs hot after normal driving
• Soft or sinking 328i brake pedal caused by a caliper piston seal leak
• Brake fluid visible around the Bmw 328i caliper piston boot
• Persistent metallic dragging noise from one 328i corner not explained by worn pads

Why GeoBrakes for the Bmw 328i Caliper Kit

Calipers for the Bmw 328i are the most position-specific brake component in the catalogue. Left and right calipers for the 328i are not interchangeable. Our vehicle selector confirms the correct caliper kit for the Bmw 328i exact year, axle position, and left or right side before purchase.

Frequently Asked Questions - Bmw 328i Disc Brake Caliper Kits

Should I replace both calipers on my Bmw 328i at the same time?

It is strongly recommended. If one caliper on the Bmw 328i has seized or leaked, the caliper on the opposite side has experienced the same conditions and age on your 328i. Replacing both restores balanced, even braking and eliminates the risk of the second 328i caliper failing shortly after the first is replaced.

Do I need to bleed the brakes on my Bmw 328i after installing a caliper kit?

Yes. Opening the hydraulic circuit on the Bmw 328i to install the new caliper allows air to enter. After installation, the brake circuit on the 328i must be bled at the caliper bleeder screw to purge all air and restore a firm, consistent brake pedal on your Bmw 328i.

What is the difference between a new and remanufactured caliper in the Bmw 328i kit?

A new caliper for the Bmw 328i has no prior service history and is the stronger choice for high-corrosion environments. A remanufactured caliper uses an original 328i housing rebuilt with new pistons, seals, and boots, performing identically to new at a lower price point for most Bmw 328i applications.
