Kia Optima Disc Brake Caliper Kit in US

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

What Is Included in the Kia Optima Disc Brake Caliper Kit

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

When a Caliper Kit Is the Correct Service Choice for the Kia Optima

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

New vs. Remanufactured Caliper for the Kia Optima

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

Signs the Caliper Kit on Your Kia Optima Is Due

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

Why GeoBrakes for the Kia Optima Caliper Kit

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

Frequently Asked Questions - Kia Optima Disc Brake Caliper Kits

Should I replace both calipers on my Kia Optima at the same time?

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

Do I need to bleed the brakes on my Kia Optima after installing a caliper kit?

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

What is the difference between a new and remanufactured caliper in the Kia Optima kit?

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