Buick Regal Sportback Disc Brake Caliper in US

The disc brake caliper on the Buick Regal Sportback is the hydraulic clamp at the centre of your Regal Sportback disc brake system. Every time you press the brake pedal on your Buick Regal Sportback, 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 Regal Sportback interferes with that process at the source, causing uneven braking, accelerated pad and rotor wear, and pulling to one side that worsens over time.

Frequently Asked Questions - Buick Regal Sportback Disc Brake Caliper

Should I replace brake calipers on my Buick Regal Sportback in pairs?

It is generally recommended to replace calipers as an axle pair on the Buick Regal Sportback, both left and right on the same axle, to maintain balanced braking. If one Regal Sportback 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 Regal Sportback in US?

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

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

Yes. A Regal Sportback 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 Regal Sportback. This rapidly wears both the pad and rotor surface on your Regal Sportback and generates enough heat buildup to damage adjacent components over time.
