Pontiac G3 Disc Brake Caliper in US

The disc brake caliper on the Pontiac G3 is the hydraulic clamp at the centre of your G3 disc brake system. Every time you press the brake pedal on your Pontiac G3, 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 G3 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 Pontiac G3

• Pontiac G3 pulls strongly to one side during braking, a seized caliper on one side applies more force
• Brake pedal on your G3 feels soft or spongy and improves after pumping, caliper piston seal leaking
• One brake pad on your Pontiac G3 axle wears significantly faster than its partner
• Brake drag on the Pontiac G3, vehicle feels like it is fighting resistance at normal road speed
• Visible brake fluid leaking from the G3 caliper body or around the piston boot
• Grinding or scraping from one Pontiac G3 wheel that persists after confirming pads are not worn

New OEM-Spec vs. Remanufactured Calipers for the Pontiac G3

New OEM-Specification Calipers for the Pontiac G3

New OEM-specification calipers for the Pontiac G3 are brand-new units manufactured to the exact piston dimensions, seal specifications, and material tolerances of the original G3 factory part. They offer the longest service life on your Pontiac G3 and are the strongest choice for higher-mileage G3 vehicles or those operated in high-corrosion environments.

Remanufactured Calipers for the Pontiac G3

Remanufactured calipers for the Pontiac G3 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 Pontiac G3 replacement applications and offer excellent value.

Frequently Asked Questions - Pontiac G3 Disc Brake Caliper

Should I replace brake calipers on my Pontiac G3 in pairs?

It is generally recommended to replace calipers as an axle pair on the Pontiac G3, both left and right on the same axle, to maintain balanced braking. If one G3 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 Pontiac G3 in US?

Pontiac G3 calipers typically last 100,000 to 150,000 kilometres, but American road salt and moisture accelerate corrosion of G3 caliper guide pins, slide pins, and piston seal boots, often causing premature failure on the Pontiac G3 well before that figure.

Can a sticking caliper on my Pontiac G3 damage my brake pads and rotors?

Yes. A G3 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 Pontiac G3. This rapidly wears both the pad and rotor surface on your G3 and generates enough heat buildup to damage adjacent components over time.
