Workhorse brake pads can require caliper piston-size and casting identifiers to distinguish brake packages within a chassis range. Those details belong with the complete vehicle application. Compare suitable sets at A-Premium by pad dimensions, friction material and supplied accessories to plan the replacement parts for your chassis.

OUTWorkhorse brake pads can depend on caliper details that a chassis name alone does not identify. Caliper piston size and casting identifiers can distinguish brake packages within a chassis range. Keep those identifiers together when selecting the replacement. The pad set's dimensions, friction material and supplied accessories then help define the purchase, while inspection of the existing discs and calipers establishes the full repair required.
For one 2010?2011 W42 application, the required identifiers include 52 mm caliper pistons and Brembo casting number 2x 52/28-929305. Together, these identify the caliper arrangement that the selected pads must work with.
A caliper casting identifier can distinguish assemblies that otherwise share a chassis description. Match it with the stated year and piston condition instead of using a brand name alone to select pads. A brake-package designation describes mechanical requirements, not a quality grade that can be substituted during an ordinary pad replacement. If the installed assembly differs from the vehicle's original equipment, establish its actual requirements with the installer. The replacement should suit the caliper and disc arrangement that will remain in service.
A piston-size condition belongs to its stated vehicle and year entry. Do not merge neighboring entries into an unrestricted year range or assume that every chassis with the same name uses the same caliper.
The caliper's piston arrangement can help identify the factory brake package. That information remains useful when the purchase is only for pads or rotors, because those friction parts must work with the installed caliper and bracket. Read the complete condition, including any named caliper type or exclusion. A front-caliper detail may also identify a vehicle package for a rear-brake purchase. The fitment note explains which system the part serves; replacement calipers are included only when they appear in the component list.
Pad height must agree with the remaining dimensions and backing outline required by the identified Workhorse caliper.
Pad height and width describe the friction and backing-plate dimensions, while the complete outline determines how the pad sits in its supports. Tabs, contact points and the relationship with the caliper also matter. Select the specified configuration for the axle before comparing friction materials or accessories. A similar-sized pad can still have a different backing shape or support arrangement. Keep the full part application with its dimensions, including any caliper or brake-package conditions that distinguish versions of the same vehicle.
A front pad set supplies four individual pads for its stated front application. That count describes friction pieces, not four complete axle sets. Check the installation position and accessory entries together so the purchase accounts for the pads and any additional fittings required by the repair.
Ceramic friction material does not override caliper-piston and casting conditions that determine the application. Choose the matching assembly first, then compare formulations. A ceramic description alone does not establish compatibility with another Workhorse brake package or promise a fixed service interval.
A front pad set is a pad-only purchase. If inspection also calls for discs, compare matching Workhorse brake rotors and carry the same chassis and brake-equipment conditions through the selection. The existing discs must meet their thickness and condition requirements if they are to remain in service.
A reference number is a useful starting point, but it should agree with the product's application conditions and component specifications. Resolve any conflicting axle, brake-package or dimensional information before ordering. Treat the reference as part of the identification process, rather than overriding a stated exclusion because one number appears familiar.
A fixed distance cannot establish the remaining condition of every brake assembly. Driving, operating conditions and the installed parts all affect wear. Follow the vehicle's inspection requirements and assess the actual friction surfaces against their applicable limits. A material or package description is not a guaranteed service-life figure.
