So I have one the of HRC Racing Rear Brake Reservoir Kits, like this: https://www.ebay.com/i/151639233201?chn=ps However after removing to clean whilst replacing rear caliper I'm having issues getting it to seal again. Does anybody have any idea what the I/D of the tube is, and/or what material it's made from? Thinking I can replace the tube with something generic this time around..
I’ve got a tube from Tygon and the internal diameter is 6 mm, it is a tight squeeze but no leaks and no discolouration.
Remember if this the real HRC kit that the tube will sweat and is not meant to survive direct UV sun exposure over time and is expected to be replaced within the racing season.
