Just check with the custodians at your job and see if you can get a green Scotchbrite pad(or part of one). ..... Of course I'm exaggerating, as far as the frequency/level of noise, but the noise is noticeable during rainy ides on the street, on dew-y early morning trail rides, and on long rides where the discs get hot. I'm pretty sure Avid BB-_'s are the most popular, and I was running BB7s BITD when I was a disc guy (I actually just bought a BB7 to run up front on an upcoming project, but /I digress.) I see that current BB7s come with sintered pads, but I don't know what came stock in years past, nor am I sure what's on the offending squawkers today, but it's worth looking into. The issue I had with my disc-equipped bike had mostly to do with long trail rides and/or sustained downhills, which led to warped rotors. Warped rotors equals rubbing on the pad, which made a little whisper of a noise all the time and lost efficiency, plus annoying squeals if I was feathering the brakes or applying any low-level of pressure. I could "fix" it by dialing out the pads or cable tension, but that led to sloppy feel at the lever and, or I could try to straighten the rotor and stuff but, in the end, it was a way bigger hassle than v-brakes, which are quiet and plenty strong enough for xc-type riding and JRA/commuting, which is the kind of riding I do anyway. Rim brakes need what? A pad adjustment from time to time as the pads wear and ride up, plus the wheels need to be pretty true. Fact is, you should keep your wheels fairly true even with hub-brakes, so NBD. As someone whose rim brakes are in-tune and can stop the bike quickly and surely, I fail to see how the added weight/expense/noise/hassle of disc brakes will help me for commutes and casual trail riding.... As for green scotch brite pads: they sell those at every grocery store. No need to pester the custodian...:thumb: |
Brown 'scotchbrite' at the hardare store has abrasive grit in it, stocked with the sandpaper , here.

Robust, low-maintenance, all but vandal-proof, and above all, impervious to weather. The brakes on the Bixi / Citibikes may not be the best in the world, and you can definitely feel differences in the adjustment as you move from one bike to another as I do every day, but like discs they are totally impervious to rain, snow, etc. You can ride a Citibike through several inches of snowy slush (and I have on many occasions) with no loss of braking effectiveness whatsoever. Tire traction is another matter entirely, but that's just a question of rider skill. For those interested, here are the Citibrakes, rear and front: http://img10.imagefra.me/i942/thradd..._d6e_u77ts.jpg http://img10.imagefra.me/i542/thradd..._819_u77ts.jpg |

With mechanical disc brakes, you basically just have one screw to turn, which moves the fixed pad in and out, and then a second adjustment for the moving pad which is similar to any other cable-operated brake. That's it. With rim brakes, you have those same adjustments, plus you have to set the spring-centering with two more screws, plus you have to set the alignment of both pads in four axis (height, rotation, toe and camber), all of which are simultaneously locked and released with a single screw. I find this to be much more difficult and time-consuming than just setting the in-out position of a disc pad to compensate for wear.

Discs are not significantly more expensive than rim brakes. This might have been true at one time, but the Chinese have gotten on-board now. If you add in the fact that disc brakes do not abrade the rim and will tolerate some runout, they can actually wind up being cheaper over time. Discs are not universally noisier than rim brakes. While there may be some rim-brake compounds that are significantly quieter than some disc-brake compounds, I can say quite affirmatively that the rim brakes on my current Schwinn (SwissStop green front, OEM black rubber rear) are much louder than the Tektro Novelas on my Giant Revel 1 (the e-bike) under hard braking. And far from being more hassle, discs, in my experience, are significantly LESS hassle than rim brakes. I have literally never done anything at all to the discs on my e-bike (which is very heavy and runs at 25-30 MPH) other than occasionally nudge the pads in and replace them once a year or so. As for weight, well, I have to admit that I've never weighed a complete disc setup and a complete rim setup. If a difference does exist, then we're literally talking about a few ounces. That might matter to an olympic-level cyclist, but to even mention it in the context of a commuter is ludicrous. I ride steel-framed bikes with fenders and cargo baskets and carry a Kryptonite lock that weighs a couple of pounds. To argue that disc brakes are worse that rim brakes in this context because of their weight makes me thing you're just trying to be deliberately contrarian. I race in Cat-6, not Cat-1. :rolleyes: |
Anyway, finished the front rim last night and buffed the other pad.
http://img15.imagefra.me/i842/thradd..._bda_u77ts.jpg Did a quick-n-dirty test this morning, dumping some water onto the front and then doing a few hard stops. It's definitely improved a great deal. It's a long way from disc performance, but I can probably live with it. Not an entirely definitive test since there's no ice on the rim, but it looks like we're done with snowfall for the year at this point. So, I think I'll be ordering another one of these bikes and setting it up identically to the first one, with the exception that I'll probably go with 700x40 tires rather than 700x35, simply because of the fact that the roads in Manhattan are much worse than in Hoboken in terms of steel plates, exposed cobblestones, potholes with jagged edges, etc. Any reason why I should pick something other than my usual Michelin City this time? (Cheng Shin Crucible, Kenda Kwest, etc...) |

Just curious, do you plan to change the brake pads after all?
In the rear, I will probably leave the OEM black rubber in place and simply sand it down once I've got the paint fully stripped off of the rear rim. (Schwinn didn't rattle-can these wheels, incidentally. That's some seriously hard catalyzed enamel they put on there which is pretty time-consuming to get off.) On the front of this bike, I will probably leave the SwissStop GHP2 pads in place, at least for now. On the front of the new bike, I think I will probably pick up a set of Kool-Stop Salmons so that I can do some back-to-back comparison of them against the SwissStops once the rainy weather picks up again. |

I see bikes every Saturday (I'm shop lead at my local co-op) that have 30+ year old wheels on them and seldom see a bike with worn out rims. It happens...I've worn out 3 rims in 30+ years and ~100,000 miles of riding...but it's not as big an issue as many people would have you believe. If you drag your brakes all the time, you'll wear out a rim but if you brake effectively, it's not that much of an issue. Finally, hub mounted disc brakes will tolerate some runout at the rim but they won't tolerate any more run out at the braking surface than rim brakes. In fact they will tolerate less because there isn't much gap between the pads and the rotor. A bend in the rotor of less than a millimeter will result in brake rub or even complete stoppage. Neither system is perfect but then neither system is vastly better than the other. |

OTOH,sometimes it takes serious effort to quiet rim brakes;sometimes it's the fork that's the issue. Specialized actually spec'd their Tricross with mini-V's one year so they could have the time to get the forks right and eliminate the chatter.

Hold on a second. If we are talking about simply adjusting for pad wear, rim brakes are no more fiddly than discs. To adjust for wear (only) on rim brakes, you simply have to take in the slack on the cable.

We're talking street riding here,not MTBing. All kinds of things break when MTBing. I've even played polo with bikes with disc brakes(3 of them),and have friends who use them,and I've never seen what you described happen.

Full disclosure: I've only run discs on trail bikes b/c, well, that's pretty much what they were designed for. As of right now, I don't have any bikes with discs.
Rim brake pads are quick and easy to adjust or set up, if you've done it a million times and you're good a it. Disc brakes are probably easier to set up if we're just talking pad adjustment, but I've found disc brakes to be a PITA overall. Yes, they work. Ppl who really love discs can easily live with the quirks that irk me. I'm not denying that. But discs provide a trade-off of benefits versus annoyances on the trail. Discs offer no real benefit on the street, at least not how I ride. I could see how they might be helpful for someone touring fully loaded in the mountains, where other brake systems would overheat and fade. But for riding to work, even in nasty weather, they can't do anything that my v-brakes can't. I managed to straighten my rotors out when they warped, but it seemed that they'd warp again in short order. Maybe I was doing it wrong, but I've reverted to Vs on my mtn bikes and I'm happy. My street bikes are equipped with cantis, Us, Vs, dual-pivot calipers, coasters, and drums (not all on the same bike, obviously). About the only system I don't like is the disc, but I've got a disc front/fixed rear project in the works. I'm hoping the disc won't frustrate me too often. PS- it really isn't sufficient to just take up the slack when adjusting for wear on a v-brake. For googleable reasons that I cannot articulately explain, v-brake pads travel upwards on the braking surface as they wear. So, you do have to kinda play with the pad adjustment a wee bit wile adjusting for wear. |

And you shouldn't need to "true the brake track" with a new rotor,unless it was damaged.
And I have yet to install a new rotor that doesn't need to be trued. So far, that about 2 dozen rotors.

Bull. Hit a pothole and your wheel can be messed up enough that you have to open your rim brake to get the wheel to turn. It would take a serious hit,that would also prolly damage something else as well,to bend a rotor bad enough to foul the caliper and stop the wheel. And bending a rotor back is way easier than truing a wheel.
I've also seen sticks jammed in disc rotors that almost folded the rotor in half and made the bike basically unrideable. It put a kink in the rotor that would take a hammer and flat surface to straighten out. It wasn't something that could be easily straightened with most multitools.

Aaah, the joys of urban bicycle maintenance:
http://img10.imagefra.me/i243/thradd..._b43_u77ts.jpg After getting the rear rim sanded down and the pads clean, I took it back down to the street as I remembered that there's one large area which tends to hold an inch or two of water after a good rain like we had a few days ago, and lo and behold, it was still flooded. Took the bike down into that region and did some hard braking tests. Performance is definitely improved. It's still a far cry from perfect consistency, and I was unable to lock the front wheel no matter how hard I tried even with the wheel submerged in two inches of water but it's better than it was. There's also an interesting new behavior which I'd not seen before. When I get on the front brake really hard (this is the one with the SwissStop green pads) there's a severe juddering. It's not caused me to lose control, but it's definitely odd... |

Having completed the work, I can say affirmatively that these brakes still squeal a lot more than the discs on my e-bike. I'm not sure why you seem to think that all disc brakes are loud, or why the loudness of a brake system is more important than how well it performs.

Thanks. All of the pads sanded down to a nice-looking surface without losing too much thickness, and in the front, the rims have already started to take on a greenish tint where there's obviously some transfer of material taking place from pad-to-rim. I do still intend to pick up some Salmons, though I'll probably install them on the other bike. Will likely be picking up another Wayfarer / Admiral shortly. |
Very practical bike man, and how well are your brake pads toed in? Depending that could account for the "juddering" I also seem to recall something about hand sanding rims and getting uneven braking surfaces that caused things like that, although given the wear and grit etc I've seen on lots of perfectly functioning rims for braking purposes that does seem kinda fishy. Oh and what is that hanging off your rack in the pic?
Oh and Surreal, I have to disagree. Discs offer a great advantage for commuting IMO, weights not exactly a huge issue and even cheap discs can eventually be dialed in to near silence. Ideally I'll be converting a frameset to use some soon as I do now often commute on wet roads, and I rather do fancy the idea of being able to use my waterproof brake a lot without having to worry about overheating (My main wet ride commuter is coaster brake for the same stopping principles). |

Is it? Steps required after changing pads in a disc system: 1: Turn inner adjuster until pad just brushes against disc. 2: Turn outer adjuster until pad just brushes against disc. Steps required after changing pads in a rim system: 1: Place shim between trailing edge of left pad and rim 2: Squeeze brake lever with one hand. 3: Use second hand to orient pad in height, yaw and roll. 4: Use third hand to tighten nut, the act of which causes roll orientation of pad to change. 5: Use vise-grips to hold pad in roll orientation with fourth hand, and re-tighten nut. 6: Place shim between trailing edge of right pad and rim 7: Squeeze brake lever with one hand. 8: Remembering lesson learned in step 5, use the vise-grips first this time. 9: Tighten right nut. 10: Adjust cable. 11: Adjust spring tension on both sides, going back and forth several times. 12: Realize that the rim is too far out of true for your liking. 13: Spend an hour truing the rim. 14: Repeat steps 10-11. |

I see you mention drum brakes, I've often tinkered with the idea of running a front one for the same reasoning as disc brakes. I also see you use them for commuting, I'm trying to restrain myself these days so I'm ignoring the other conversation as best I can ;) So would you mind telling me your thoughts and experiences with them as a commuter? |

It fit perfectly onto the rack which came with the bike. Exactly the right size to hold one paper grocery bag. I have these on all my bikes. |
