Diploma in Disc and Drum Brakes for Heavy Vehicles
Online postgraduate diploma of 800 hours in disc and drum brakes for heavy vehicles, structured in 8 modules covering braking physics, drum and disc brakes, friction materials, actuation systems, thermal behaviour and testing, with UNECE R13, UNECE R90 and Ansys Mechanical, with an assigned technical tutor.
Diploma in Disc and Drum Brakes for Heavy Vehicles — studying from New Zealand
Vehicle restoration and classic engine work in New Zealand is supported by an active enthusiast community and a well-established network of specialist workshops, particularly around the main centres. Historic vehicle registration and compliance fall under the New Zealand Transport Agency Waka Kotahi, and the Vintage Car Club of New Zealand promotes preservation of historic vehicles. Restoration professionals often combine fabrication, engineering and heritage conservation skills.
Fees for New Zealand: NZ$2,550 (New Zealand dollar), with instalments and employer sponsorship available.

Questions from New Zealand
Is restoration engineering recognised by a professional body in New Zealand?
There is no specific statutory register for classic vehicle or heritage restoration engineers in New Zealand. Heritage matters can involve Heritage New Zealand Pouhere Taonga, and vehicle roadworthiness is governed by the NZ Transport Agency Waka Kotahi. SEIUM's qualifications are private and not accredited by any national body, so their value depends on the employer or client.
Where do classic restoration specialists work in New Zealand?
Work is found in independent restoration workshops, classic car dealers, museums, and specialist fabrication businesses, many clustered around the main centres. Clients and employers usually judge by workmanship and a portfolio of completed restorations. A private qualification may complement that evidence but is rarely a deciding factor on its own.
Can I study this while running or working in a workshop here?
Yes. The course is fully online and taught in English, so you can study from home in New Zealand without a student visa. Specialist courses total 300 hours, postgraduate diplomas 800 hours and master's programmes 1,900 hours. An assigned technical tutor supports you, and fees can be paid in instalments.

How you'll learn
A 100% online programme on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. There are no fixed timetables: you progress at your own pace within each intake, so you can combine it with work.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is Ansys Mechanical, MATLAB/Simulink, Simcenter Amesim and HBK nCode, in free, academic or evaluation versions. Testing is studied through real procedures for dynamometer friction tests, thermal modelling of brakes on descents and roller brake tester inspection. Assessment is continuous by module, plus the final project.
Standards covered: UNECE Regulation R13, UNECE Regulation R90, ISO 3450, SAE J2522, ISO 4925, Directive 2014/45/EU, ISO 26867.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
