4. Preparing the Brake Pipe
Important: ALWAYS ensure that the brake pipe is
correctly prepared before aring.
• The end of the pipe MUST be cut square.
• The outside edge of the pipe must be
champfered by approximately 0.25mm at 45°.
• The bore of the pipe must be deburred.
• If the pipe is plastic-coated, remove at least
3mm from the end of the pipe to be ared,
ensuring that the pipe is not scored and that no
metal is removed while doing so.
Important: DO NOT use an abrasive cloth on the end
of the brake pipe to be ared.
