Frequently Asked Questions (FAQ)
What components are included in a commercial vehicle air disc brake caliper repair kit?
A comprehensive caliper repair kit includes induction-hardened guide pins, brass or composite bushings, heat-resistant EPDM dust boots (-40°C to +200°C), ring seals, adjuster pinion shafts, chains, tappet heads, and calibration components tailored to specific OEM systems.
How do I find the correct caliper repair kit using OEM or cross-reference numbers?
You can enter any OEM number (e.g. Wabco 6402229202, Knorr K000944, Schmitz 1199858) or vehicle manufacturer part number directly into our search bar. Our cross-reference database will instantly match the precise GOS Brake product code and technical drawing.
How often should caliper guide pin kits and dust boots be serviced or replaced?
Caliper guide pins and rubber boots should be inspected at every brake pad replacement. If there is boot tearing, water ingress, or guide pin play, replacing the kit prevents caliper seizure, uneven pad wear, and catastrophic brake failure.
Are GOS Brake Systems caliper parts fully compatible with original OEM assemblies?
Yes. All GOS Brake caliper components are manufactured to strict OE specifications in dimension, metallurgic composition, and heat-treatment standards, providing 100% interchangeable direct replacement for Knorr, Wabco, Meritor, and Haldex calipers without modification.
