Buick Lacrosse Disc Brake Caliper Kit in US

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

What Is Included in the Buick Lacrosse Disc Brake Caliper Kit

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

When a Caliper Kit Is the Correct Service Choice for the Buick Lacrosse

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

New vs. Remanufactured Caliper for the Buick Lacrosse

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

Signs the Caliper Kit on Your Buick Lacrosse Is Due

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

Why GeoBrakes for the Buick Lacrosse Caliper Kit

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

Frequently Asked Questions - Buick Lacrosse Disc Brake Caliper Kits

Should I replace both calipers on my Buick Lacrosse at the same time?

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

Do I need to bleed the brakes on my Buick Lacrosse after installing a caliper kit?

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

What is the difference between a new and remanufactured caliper in the Buick Lacrosse kit?

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