Infiniti M45 Disc Brake Caliper in US

The disc brake caliper on the Infiniti M45 is the hydraulic clamp at the centre of your M45 disc brake system. Every time you press the brake pedal on your Infiniti M45, 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 M45 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 Infiniti M45

• Infiniti M45 pulls strongly to one side during braking, a seized caliper on one side applies more force
• Brake pedal on your M45 feels soft or spongy and improves after pumping, caliper piston seal leaking
• One brake pad on your Infiniti M45 axle wears significantly faster than its partner
• Brake drag on the Infiniti M45, vehicle feels like it is fighting resistance at normal road speed
• Visible brake fluid leaking from the M45 caliper body or around the piston boot
• Grinding or scraping from one Infiniti M45 wheel that persists after confirming pads are not worn

New OEM-Spec vs. Remanufactured Calipers for the Infiniti M45

New OEM-Specification Calipers for the Infiniti M45

New OEM-specification calipers for the Infiniti M45 are brand-new units manufactured to the exact piston dimensions, seal specifications, and material tolerances of the original M45 factory part. They offer the longest service life on your Infiniti M45 and are the strongest choice for higher-mileage M45 vehicles or those operated in high-corrosion environments.

Remanufactured Calipers for the Infiniti M45

Remanufactured calipers for the Infiniti M45 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 Infiniti M45 replacement applications and offer excellent value.

Frequently Asked Questions - Infiniti M45 Disc Brake Caliper

Should I replace brake calipers on my Infiniti M45 in pairs?

It is generally recommended to replace calipers as an axle pair on the Infiniti M45, both left and right on the same axle, to maintain balanced braking. If one M45 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 Infiniti M45 in US?

Infiniti M45 calipers typically last 100,000 to 150,000 kilometres, but American road salt and moisture accelerate corrosion of M45 caliper guide pins, slide pins, and piston seal boots, often causing premature failure on the Infiniti M45 well before that figure.

Can a sticking caliper on my Infiniti M45 damage my brake pads and rotors?

Yes. A M45 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 Infiniti M45. This rapidly wears both the pad and rotor surface on your M45 and generates enough heat buildup to damage adjacent components over time.
