Infiniti Ex37 Brake Calipers

Infiniti Ex37 Brake calipers

Brake calipers for your Infiniti Ex37 start at low prices, with multiple options in stock from top OE-quality brands. The caliper is the hydraulic clamp that squeezes brake pads against the rotor to stop the vehicle. A failing caliper causes uneven braking, pulling, or a complete loss of stopping power — making it one of the most safety-critical parts on the car.

Signs your Infiniti Ex37 needs a new brake caliper

  • Vehicle pulls sharply to one side under braking — a seized caliper applies uneven clamping force across the axle
  • Brake pedal feels spongy, sinks to the floor, or requires extra pressure — a leaking caliper piston bleeds hydraulic pressure
  • Visible brake fluid wet spots or residue on the inside of the wheel or behind the caliper bracket
  • Constant dragging sensation or the vehicle resists rolling even when you lift off the brake — a stuck piston keeps the pad pressed against the rotor
  • One rotor or wheel is noticeably hotter than the other after a short drive — caused by a caliper that will not fully release
  • Rapid, uneven brake pad wear on one corner — the stuck caliper keeps that pad in constant contact with the rotor

Which brake caliper should you buy for your Infiniti Ex37?

The two main decisions are remanufactured versus new, and loaded (with pads and hardware) versus unloaded (bare caliper only). Position also matters — front calipers handle most of the braking load and are larger, while rear calipers on vehicles with integrated parking brakes use a screw-driven piston that is not interchangeable with a standard push piston design.

Remanufactured, unloaded
Best for
Budget-conscious repairs when existing pads still have life
What you get
Rebuilt OEM-core caliper, cleaned and re-sealed; you reuse your current pads and hardware
Remanufactured, loaded
Best for
Fastest turnaround when pads are worn or unknown condition
What you get
Rebuilt caliper with new brake pads and hardware pre-installed, ready to bolt on
New (aftermarket), unloaded
Best for
High-mileage vehicles or severe-duty use where core quality is uncertain
What you get
Freshly manufactured caliper with no reused internal parts; longer expected service life
Performance / upgraded caliper
Best for
Track use, towing, or vehicles with upgraded rotors and pads
What you get
Higher-grade pistons, increased clamping force, or multi-piston design for improved heat resistance and fade control

Replacing a brake caliper on a Infiniti Ex37

Moderate⏱ 1–2 hours per axleFloor jack and jack standsBreaker bar and metric/standard socket setCaliper wind-back tool (required for rear calipers with integrated parking brake)Brake line wrench (flare-nut wrench) for the banjo bolt or brake hose fittingBrake bleeder kit or vacuum bleeder

Remove the wheel, unbolt the caliper bracket if replacing the full assembly, and disconnect the brake hose fitting before unbolting the caliper from the bracket — have a catch pan ready for fluid. Install the new caliper, torque all fasteners to manufacturer specification using a torque wrench, reconnect the brake hose, and bleed the system until the pedal is firm before driving. Always pump the brake pedal several times with the vehicle stationary to seat the pads against the rotor before moving.

Frequently asked questions

How much does it cost to replace brake calipers on a Infiniti Ex37?
Parts alone start at low prices for a single caliper on a Infiniti Ex37. Professional labor typically adds one to two hours per corner. Replacing in axle pairs — both fronts or both rears — is widely recommended to keep braking force balanced and is often more cost-effective when labor is already involved.
Should I replace brake calipers in pairs on a Infiniti Ex37?
Yes, replacing both calipers on the same axle at the same time is strongly recommended. If one caliper has failed due to age or internal corrosion, the opposite unit is likely in similar condition. Mismatched clamping force between sides causes brake pull and uneven pad wear, creating a new safety problem.
Can I drive my Infiniti Ex37 with a bad brake caliper?
No. A seized or leaking caliper is a safety emergency. A locked-up caliper can cause the vehicle to pull violently during a panic stop. A leaking caliper can result in sudden brake failure. Stop driving the Infiniti Ex37 as soon as caliper failure is suspected and have it inspected or repaired immediately.
How long do brake calipers last on a Infiniti Ex37?
Calipers on a Infiniti Ex37 typically last anywhere from 75,000 to 100,000 miles under normal conditions, but lifespan varies significantly with climate, driving habits, and maintenance history. Road salt, infrequent brake fluid changes, and aggressive driving all accelerate corrosion and rubber seal degradation, shortening caliper life considerably.
Do I need to bleed the brakes after replacing a caliper on my Infiniti Ex37?
Yes, bleeding is required. Opening the brake hydraulic system to remove the old caliper introduces air into the lines. Unbled air creates a compressible pocket that makes the pedal feel soft or spongy. Bleeding the affected corner — and often the full system — restores firm pedal feel and ensures full hydraulic pressure is restored.
What is the difference between a loaded and unloaded caliper for a Infiniti Ex37?
A loaded caliper comes with new brake pads and mounting hardware pre-installed, making it a complete, ready-to-install assembly. An unloaded caliper is the bare hydraulic unit only. Loaded kits cost more but save time, ensure pad and caliper break-in happen together, and eliminate the risk of installing worn pads on a fresh caliper.
