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