Then exactly WHY did you ask here? And of course you won't mind if there's no response in the future. I'm seriously considering unsubscribing from this group - all I ever get is patronising and insulting replies. Errrr.... You don't have to unsubscribe. You can just leave. I can't actually remember ever getting the right answer here before I figured it out by myself. And a damned good reason to leave, I'd say. Jeez, did anyone follow the thread enough to find out what the problem was? Probably too much preload on the springs causing pivot friction. Only one person came even close - and they suggested I'd made the really basic stupid mistake of setting the 2 springs to different preloads. No I didn't. The closest I came to that was suggesting that you check that they were in the same holes if the screws needed to be set radically different to each other - which was another thing that you'd never actually told us, You must've had selective blindness on all the occasions I described the things I'd tried while servicing the pivots - like trying different types of grease, and lightly sanding the pivot surfaces trying to get them to hold onto some grease. Even running a spare detachable pivot post in the electric drill to make sure the hole in the caliper arm run smooth. The only suggestions I got were all the first things I checked - to say that I'm not impressed, would be something of an understatement. If I'd asked on rec.bicycles.diy.bodger - the standard of replies I got here would have been understandable. I'm starting to wonder what terrible thing some people here did in a previous life to come back as what they did! Someone recently posted a reference to U.S. Standard regarding bicycles sold in the U.S. (Code of Federal Regulations (CFR) in Title 16, Part 1512.) There are a number of standards but the first listed reads: "(1) Adults of normal intelligence and ability must be able to assemble a bicycle that requires assembly". Given that you are, apparently, in the U.S. trying to fix/assemble a bicycle sold in the U.S. we must assume that said bicycle meets U.S. standards. Thus it is obvious that as said bicycle meets U.S. standards and you are unable to assemble/fix said bicycle that the only conclusion is that you must either be, not an adult, or not of normal intelligence. Given your long drawn out explanations and excuses for not being able to fix/assemble the bicycle the latter conclusion seems to be most likely. We're a large country with a hidden problem. Half our citizens are below average. Its a well known fact that the US has more crazies per head of population than any other country - just watch the even crazier Trump being backed well on his way to the White House. I can only assume that most of the people that replied to my question, are in the US. Spend any day in the House of Commons and you'll see your share of crazies. https://www.youtube.com/watch?v=PWeaLGealHQ These guys make Trump look like a piker. And yes, we in the U.S. answered your question -- perhaps not the answer you wanted, but then again, it was a trick question. I'm still waiting for the answer. As Andrew pointed out, it couldn't be the spring pre-load, and according to you, it was none of five things that usually cause binding. I thought we got it down to Van Der Waals forces at the brake pad. And not gyroscopic precession? No, it's clearly the Bernoulli effect of the faster airflow lowering the pressure more through one gap (or venturi) if one pad is even microscopically closer to the rim than the other, which causes the ambient air pressure to push the pad the rest of the way onto the rim. You've got that back to front. There was a "Bernoulli" computer hard drive that used the effect to keep the R/W heads *OFF* the platters. By shaping the heads to create lift, and using what is known in flight as "ground effect" but is actually the slight adhesion of any fluid to a bordering surface (thus REDUCING the Bernnoulli effect). The guys who named that drive actually didn't really understand what they were using the name for. The just wanted a distinctive name for sales purposes. All hard disc drive heads fly in that way anyway - it's the only way to keep them close to the spinning disk without hitting it.. I honestly don't think you can teach me much about the Bernoulli effect - I'm a bloody pilot, so I had to study it, pass examinations which included accurate descriptions of it's effects, and demonstrate how to apply it in the practical control of an aircraft. All I stated was; the Bernoulli effect doesn't put the R/W heads into contact with the platter. But, in a perfect frictionless system*, it would get them close enough that contact would be inevitable - if only from the surface imperfections, never mind the fact that no wheel is perfectly true. You can twist the interpretation any way you want - the facts remain facts. The facts are that none of us have a non-working brake between the lot of us - of any type, Yet no one was capable of giving the correct answer - so I hope for your sake, they don't develop a problem. |

We that advised you, all have WORKING PROPERLY ADJUSTED V-brake and using our posted trouble-shooting advice we have fixed countless other V-brakes. You however STILL DON'T have a properly adjusted V-brake. You call those who can and do fix V-brakes idiots but the real idiot is in your mirror. TROLL! Cheers |

Its "good enough", I started backing out the balance screws instead of "hilting" the one that needs the most return force. Maybe put the spring in the middle hole when I get around to doing the post winter service. |
