A complete disc brake kit for the Hummer H3 is the most efficient way to perform a full axle disc brake service on your H3. The friction components, rotor surface finish, pad compound, and caliper hardware on the Hummer H3 all function as an integrated system. Sourcing each element separately for the H3 introduces compatibility variables that manifest as brake noise, vibration, or inconsistent pedal feel in the first months of service on your Hummer H3.
The kit for your Hummer H3 includes front or rear disc brake rotors at OEM or performance specification for the H3, brake pads in ceramic or semi-metallic formulation compound-matched to the Hummer H3 rotor specification, a caliper hardware kit with slide pins, pin boots, and anti-rattle clips for correct caliper float on the H3, brake lubricant for correct caliper pin and shim installation on your Hummer H3, and rotor mounting hardware where required by the Hummer H3 application.
OEM Replacement Disc Brake Kit for the Hummer H3
Restores factory braking performance exactly on your Hummer H3, the correct specification for everyday commuting and family use of the H3 in American conditions.
Antirust Coated Disc Brake Kit for the Hummer H3
The most practical choice for American Hummer H3 drivers. Zinc-coated or e-coated rotor surfaces on the H3 resist the rust that plain rotors develop within days of road salt exposure on your Hummer H3, maintaining consistent friction performance through multiple winter seasons.
Performance Disc Brake Kit for the Hummer H3
Uses cross-drilled and slotted rotors with high-performance pads for Hummer H3 drivers who tow, drive mountain roads, or generate sustained braking temperatures beyond what factory-spec rotors manage effectively on the H3.
Caliper slide pins, pin boots, and anti-rattle clips on the Hummer H3 are the most commonly overlooked components in a brake service and the most common cause of brake noise complaints after a pad change on the H3. Sticking slide pins on your Hummer H3 prevent the caliper from floating freely, causing the outer pad to wear faster than the inner. Every GeoBrakes disc brake kit for the H3 includes fresh hardware as a standard component.
Our disc brake kit range for the Hummer H3 is built with coated rotor options at every kit level to address road salt corrosion that shortens rotor life on most American H3 applications. As an authorized retailer of Cardone, EBC, Brembo, Raybestos, and Akebono, every kit for the Hummer H3 ships with full manufacturer warranty coverage.
Should I buy a front kit, rear kit, or both for my Hummer H3?
Front brakes on the Hummer H3 handle 60 to 70 percent of braking force and wear faster than the rear. If only one axle on your H3 is due for service, buy that kit. If both axles on the Hummer H3 need service simultaneously, combining them in one order above $99 qualifies for free US-wide delivery.
What rotor type should I choose for my Hummer H3 in American conditions?
For everyday commuting on your Hummer H3, an antirust coated OEM kit is the most practical choice, delivering factory-level performance while resisting the corrosion plain rotors develop rapidly on the H3 in road salt conditions. For towing or performance driving with your Hummer H3, a drilled-and-slotted performance kit provides improved heat management.
How long do disc brake kits last on a Hummer H3?
Under normal American driving, a quality disc brake kit on the Hummer H3 typically lasts 50,000 to 70,000 kilometres. Antirust coated kits tend to last longer on the H3 because corrosion is a major cause of early rotor replacement on American Hummer H3 vehicles.
