Brake Disc for QJMotor SRK 400: Folding Type
This brake disc is built for the QJMotor SRK 400 and supplied to a written specification, so the part that comes off the line in the next order matches the one you approved. Fitment, base material and finish are fixed before sampling starts — that is what keeps the folding type programme stable once it moves from first order to repeat order.
Most buyers come to us after something went wrong: packing that arrived crushed at the port, or premature wear on the first batch. Both are avoidable when the specification is written down before bulk and the approved sample is kept as the reference.

What decides whether it lasts
- Material — Carbon Fibre Composite is the base; treat any substitution as a new approval.
- Hardness and heat treatment — recorded per lot, not per batch of paperwork.
- Fitment tolerance — checked on the actual QJMotor SRK 400 mounting, not on a catalogue drawing.
- Finish — zinc plating holds up where the machine sees salt, mud and daily washing.
- Packing — individual packing plus inner cartons sized for the workshop bench.

Fitment notes
Keep the old part until the new one is on the bench. Comparing them side by side settles questions a photograph never will.
