Greetings all -
While getting the Gobike up to snuff I've been getting familiar with mechanical discs. At first it seemed that mechanicals would be simpler than hydros due to not having to deal with liquids.
However...Mechanicals are single puck, meaning that only one pad moves, distorting the rotor to contact the stationary pad. This requires the adjustment of both the stationary pad and the cable side as the pads wear. They are also a bit fussy to get properly set up. The Tektros that came stock constantly rubbed at the rear no matter how much I fiddled with it. Not being too impressed with their quality, I picked up a set of used Hayes, which seemed to be a better build quality. These still rubbed a bit, so fixed that with shims. Seems I could have also corrected it by moving the hub over in relation to the axel, but didn't have a set of cone wrenches to make the adjustment.
This all got me thinking about hydros. As both pucks move, they are self centering and adjusting, eliminating both of the more irritating aspects of mechanicals. But there is the fluid to deal with. Having worked on both car and motorcycle brakes, I know the hazards involved, especially dealing with DOT 3/4 brake fluid. Nasty stuf that'll eat through about anything, including skin. Some systems use mineral oil, which has it's own negatives, but mostly in cold temps it seems.
I do have some questions that hopefully the more experienced members can answer. The Gobike has rather convoluted brake line routing that gets worked quite a bit when folding and unfolding. Will the hydro lines stand up to this? Also, as the lines need to be longer than what is usually supplied with most kits, I would need to buy brake line in bulk and cut my own. Any suggestions as to a recommended brand/type? There also seems to be several styles od connectors depending on brand/model. Are they all customizable? Lastly, I've seem many 'bleeding' kits taylored to specific systems. I've always just used a bit of hosing and a jar for bleeding. Are these really so different?
Thanks in advance and sorry for being so long winded.
