Buick Lacrosse Disc Brake Caliper in US

The disc brake caliper on the Buick Lacrosse is the hydraulic clamp at the centre of your Lacrosse disc brake system. Every time you press the brake pedal on your Buick Lacrosse, brake fluid pressure forces the caliper pistons outward, squeezing the brake pads against the rotor and generating the friction that stops your vehicle. A seized, leaking, or sticking caliper on the Lacrosse interferes with that process at the source, causing uneven braking, accelerated pad and rotor wear, and pulling to one side that worsens over time.

Signs of a Failing Disc Brake Caliper on the Buick Lacrosse

• Buick Lacrosse pulls strongly to one side during braking, a seized caliper on one side applies more force
• Brake pedal on your Lacrosse feels soft or spongy and improves after pumping, caliper piston seal leaking
• One brake pad on your Buick Lacrosse axle wears significantly faster than its partner
• Brake drag on the Buick Lacrosse, vehicle feels like it is fighting resistance at normal road speed
• Visible brake fluid leaking from the Lacrosse caliper body or around the piston boot
• Grinding or scraping from one Buick Lacrosse wheel that persists after confirming pads are not worn

New OEM-Spec vs. Remanufactured Calipers for the Buick Lacrosse

New OEM-Specification Calipers for the Buick Lacrosse

New OEM-specification calipers for the Buick Lacrosse are brand-new units manufactured to the exact piston dimensions, seal specifications, and material tolerances of the original Lacrosse factory part. They offer the longest service life on your Buick Lacrosse and are the strongest choice for higher-mileage Lacrosse vehicles or those operated in high-corrosion environments.

Remanufactured Calipers for the Buick Lacrosse

Remanufactured calipers for the Buick Lacrosse are original caliper housings completely disassembled, cleaned, inspected, and rebuilt with new pistons, seals, boots, and hardware. Quality remanufactured units perform identically to new calipers for most Buick Lacrosse replacement applications and offer excellent value.

Frequently Asked Questions - Buick Lacrosse Disc Brake Caliper

Should I replace brake calipers on my Buick Lacrosse in pairs?

It is generally recommended to replace calipers as an axle pair on the Buick Lacrosse, both left and right on the same axle, to maintain balanced braking. If one Lacrosse caliper has failed, the caliper on the opposite side has experienced the same service conditions and is likely at a similar stage of wear.

How long do disc brake calipers last on a Buick Lacrosse in US?

Buick Lacrosse calipers typically last 100,000 to 150,000 kilometres, but American road salt and moisture accelerate corrosion of Lacrosse caliper guide pins, slide pins, and piston seal boots, often causing premature failure on the Buick Lacrosse well before that figure.

Can a sticking caliper on my Buick Lacrosse damage my brake pads and rotors?

Yes. A Lacrosse caliper that does not fully retract keeps the brake pad in partial contact with the rotor between stops, generating constant friction and heat on your Buick Lacrosse. This rapidly wears both the pad and rotor surface on your Lacrosse and generates enough heat buildup to damage adjacent components over time.
