Quality control
For your peace of mind
All Winnard Brake Discs and Brake Drums are manufactured to our specifications and controlled through our stringent quality control procedures.
To ensure complete dimensional and material conformity we check every batch through our quality control system which utilise our two three dimensional Co-ordinate Measuring Machines (C.M.M's)

Systems and Procedures
Our ISO9001 approved quality control procedures, which have been incorporated into our bespoke product database and manufacturing control systems, provide us with the necessary knowledge and structure to control the quality of our Commercial Vehicle Brake Discs and Brake Drums.
Every part checked is recorded on our "in-house" designed and created manufacturing database which integrates with our full systems software.


Not all Brake Discs are the same
Without specialised measuring equipment and detailed material analysis it is impossible to ascertain the quality of any Brake Discs supplied. Even with this equipment you still require the technical knowledge and engineering experience to interpret the information.
Better by design.
It is our continuing aim to improve the quality of the products we manufacture. Our Product Development and Engineering Departments are always striving to improve the design and operation of our products.
