Bmw 330i Disc Brake Caliper Kit in US

When a caliper on the Bmw 330i seizes, leaks, or drags, the damage does not stop at the caliper. A partially seized caliper on your 330i 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 330i 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 330i together.

What Is Included in the Bmw 330i Disc Brake Caliper Kit

The kit for your Bmw 330i includes the disc brake caliper at the correct left or right hand specification for the 330i, either new OEM-spec or quality remanufactured to the Bmw 330i piston dimension and hydraulic pressure rating, brake pads in ceramic or semi-metallic formulation matched to the 330i caliper and rotor specification, caliper hardware with slide pins, pin boots, and anti-rattle clips for correct caliper float on the Bmw 330i, brake lubricant for correct pin and shim installation on your 330i, and copper washers or banjo bolt seals for the brake hose connection where required by the Bmw 330i application.

When a Caliper Kit Is the Correct Service Choice for the Bmw 330i

A caliper kit is the right call for the Bmw 330i in three specific situations. After a seized or dragging caliper, because the pads and often the rotor on your 330i are already compromised. During a high-mileage 330i overhaul at 150,000 kilometres or more, because caliper piston seals and guide pin boots on the Bmw 330i are typically at or beyond their service life. After a brake fluid leak at the caliper, because fluid contamination of the 330i brake pad renders the friction material permanently ineffective on your Bmw 330i.

New vs. Remanufactured Caliper for the Bmw 330i

New OEM-specification calipers for the Bmw 330i are manufactured from fresh materials with no prior service history, the strongest choice for 330i vehicles in high-corrosion environments. Remanufactured calipers use original Bmw 330i housings rebuilt with new pistons, seals, and boots, performing identically to new units at a lower price point for most 330i replacement applications.

Signs the Caliper Kit on Your Bmw 330i Is Due

• Bmw 330i pulling to one side during braking, one caliper applying more force than the other
• One brake pad on your 330i worn significantly more than its pair on the same axle
• Brake drag on the Bmw 330i with a wheel that runs hot after normal driving
• Soft or sinking 330i brake pedal caused by a caliper piston seal leak
• Brake fluid visible around the Bmw 330i caliper piston boot
• Persistent metallic dragging noise from one 330i corner not explained by worn pads

Why GeoBrakes for the Bmw 330i Caliper Kit

Calipers for the Bmw 330i are the most position-specific brake component in the catalogue. Left and right calipers for the 330i are not interchangeable. Our vehicle selector confirms the correct caliper kit for the Bmw 330i exact year, axle position, and left or right side before purchase.

Frequently Asked Questions - Bmw 330i Disc Brake Caliper Kits

Should I replace both calipers on my Bmw 330i at the same time?

It is strongly recommended. If one caliper on the Bmw 330i has seized or leaked, the caliper on the opposite side has experienced the same conditions and age on your 330i. Replacing both restores balanced, even braking and eliminates the risk of the second 330i caliper failing shortly after the first is replaced.

Do I need to bleed the brakes on my Bmw 330i after installing a caliper kit?

Yes. Opening the hydraulic circuit on the Bmw 330i to install the new caliper allows air to enter. After installation, the brake circuit on the 330i must be bled at the caliper bleeder screw to purge all air and restore a firm, consistent brake pedal on your Bmw 330i.

What is the difference between a new and remanufactured caliper in the Bmw 330i kit?

A new caliper for the Bmw 330i has no prior service history and is the stronger choice for high-corrosion environments. A remanufactured caliper uses an original 330i housing rebuilt with new pistons, seals, and boots, performing identically to new at a lower price point for most Bmw 330i applications.
