Practical, no-nonsense guides on air brake systems, preventive maintenance and OEM-quality aftermarket parts — written for fleet operators, workshops and parts buyers.
Four focused knowledge areas covering the questions parts buyers actually ask.
How truck air brake systems work — compressors, dryers, valves, chambers and slack adjusters — with practical service and replacement guidance.
4 guidesPreventive maintenance schedules, wear symptoms and step-by-step service knowledge for the parts that keep heavy commercial vehicles on the road.
4 guidesOEM vs aftermarket explained: quality standards, cross-referencing part numbers, choosing suppliers and avoiding counterfeit truck parts.
4 guidesWhere the commercial vehicle industry is heading — emissions rules, electrification, safety systems — and what it means for spare parts.
Start with the guides our readers use most.
ABS stops wheel lockup; EBS replaces the pneumatic control signal entirely. How each system works, the component differences, EU mandates, and the service habits each one demands.
What GSR2 actually mandates on heavy trucks, how each ADAS sensor works, and what calibration, brake health, and parts availability mean for your maintenance budget.
Verifiable market size estimates, IAM vs OES share shifts in Europe, Türkiye's rise as a parts manufacturing hub, and what today's aftermarket trends mean for fleet parts buyers.
Moisture quietly kills air brake systems. How desiccant dryers and purge cycles work, the failure signs to catch early, and realistic cartridge replacement intervals by duty cycle.
What Type 24, Type 30 and long-stroke actually mean, how push rod stroke decides braking force, and the safety rules that keep spring brake work from turning deadly.
The A/B/C/D preventive maintenance framework for heavy trucks: interval tables by system, daily walkaround essentials, seasonal prep, and the cost math that makes PM pay for itself.
A modern truck spends its life measured in millions of kilometres. The difference between a part that lasts and a part that fails on the road comes down to materials, tolerances and testing — not the logo on the box.
That's why we focus on what "OEM quality" actually means, how to cross-reference part numbers correctly, and how to choose suppliers you can trust — like Vaden Original, which manufactures OEM-compatible air brake and engine components in a 105,000 m² facility and ships to 110+ countries.
Decode OE number formats from Mercedes to Scania, trace supersession chains, and follow a six-step workflow to cross-reference any truck part number with confidence.
Clear definitions of OEM, OES and aftermarket, the three aftermarket quality tiers, a full comparison table, and the fleet TCO math showing when each choice pays.
A practical due-diligence checklist for vetting truck spare parts suppliers — plus the red flags, markings, and packaging checks that keep counterfeit parts out of your fleet.
BEV and FCEV trucks are coming - but slowly. What disappears, what stays, what grows, and how fleets and parts distributors should plan for a diesel parc that runs into the 2040s.
Euro 7 is law: trucks comply from 2028-2029. What changes vs Euro VI, why brake-dust limits reshape the friction market, and what fleets and workshops should do now.
Decode OE number formats from Mercedes to Scania, trace supersession chains, and follow a six-step workflow to cross-reference any truck part number with confidence.
Clear definitions of OEM, OES and aftermarket, the three aftermarket quality tiers, a full comparison table, and the fleet TCO math showing when each choice pays.
What slack adjusters do, manual vs automatic, how to check free stroke and applied stroke, the legal CVSA stroke limits by chamber type, and when to stop adjusting and replace.
Follow the air from compressor to brake chamber: supply circuit, dual circuits, control valves, spring brakes, foundation brakes, and the health checks every fleet should run.
