|   Brake/rims suck beyond suckdom | ernesto
Sep 12, 2002 6:23 AM | | Is anyone running Velocity rims? I can't get the squeal out of mine. My rims are not machined, could that be the problem? I have Sachs brake pads on front and they still have a lot of meat. I think the only alternative would be to try new pads. DA! It drives me nuts! The rear is alright, but the front squelas like a pig being prepped for castration by a FFA student (I was one, and castrated a pig for a grade in high school).
Any suggestion would help. |

| here's a suggestion... | sslos
Sep 12, 2002 8:12 AM | | never, NEVER admit that you've castrated a pig!
seriously, try some different pads, and scrub down your rims w/ a scotchbrite pad. that'll get the rubber residue off of 'em. if that doesn't work, rough up the brake pad w/ some sand paper or a file.
hope that helps!

Sep 12, 2002 8:52 AM | | I think I am getting new pads, and if that fails, I'll try v-brakes with a travel agent (drop bars/road levers combo). If all fails. I will take the plunge to get an Avid mechanical disc brake set up with a new fork.
As pigs go, it was brutal for a grade. In this day and age, who knows if they allow that in school. I also took a hunter's ed. class in my high school, where the teacher brought in his guns, live ammo, and we had to learn about hunting, proper gun handling, etc...and for a grade, we had to skin a racoon. |
| What kinda brakes? | dgoodisi
Sep 12, 2002 8:17 AM | | You mentioned Sachs pads, are they the SRAM brakes?
If their Shimano XTs then it's probably the brakes, and not much you can do about it.
Every XT brake I've seen on the front squeeled like that pig you castrated. Now the newer ones might not squeel anymore, but the ones from just a couple years ago, with the parallel push design, are LOUD.
(anyone want a slightly used set of XT brakes?) |

Sep 12, 2002 8:42 AM | | I have old school Sachs cantis. I think I should just get new pads. The rim is not machined, so I should have given it more thought on getting them. The rear brake is ok, but the front is a bit hard to toe in.
I have tried everything. From sanding the pads, etc. to witnessing a full moon wearing only a couple of apples in my armpits.
DA! I wish I could put a disc brake on the bike! |
| toe the pads... | maun
Sep 12, 2002 9:28 AM | | The pads need to contact the rim at a slight angle....very slight...front touches first then the rear. If the pads contact flat, you'll get the squeal.

Sep 12, 2002 10:47 AM | | The second Ute in our family has Paul Motolite brakes. I cursed them from day one - they always squealed front and rear. Velocity rims, too. I finally "took the cure" - and spent a good 10 minutes per rim with [red; fine] Scotchbrite pad. It took real elbow grease. At first, the rims were almost impossible to abrade - they must have had some serious oxide. I deglazed the pads by rubbing them on sandpaper held flat on a workbench. Smmoth, quiet and strong braking action now. My apologies to Paul.

| thanks! | ernesto
Sep 12, 2002 1:05 PM | | a-ha! I guess I'll try that. I'll use a Scotchbrite pad like you say. Elbowgrease is good as a goose.
Still, I'll buy new brake pads for front and rear a la choy. |
| A totally counter intuitive brake trick! | Usedtobfast
Sep 12, 2002 3:54 PM | | Ok, so if you have adjusted the toe-in, and abraded the rims, and deglazed the pads, and the thing still squeaks like your previously mentioned farm yard relationships just give this a try.
Adjust one pad with the "normal" toe-in that you would use, i.e. the end of the pad towards the front of the bike is closest to the rim. Now on the other side (this is the counter intuitive part here) adjust the pad with toe-out so that the closest part of the pad is towards the rear of the bike and your pads end up situated like a parallelogram on either side of the rim.
Sounds weird I know, but I learned this trick from a wise old bike mechanic (hope he's lot lurking around here somewhere) and it has worked before when nothing else has solved the problem.

| I SECOND THIS TRICK | CalMTB
Sep 13, 2002 9:16 AM | | My front Avid Arch Supreme came with this toe-in toe-out design and it seems to work squeak-free. How ever, when I tried to readjust the pads to toe-in only, it started to squeak. So now I'm back to this trick. Give it a try and see if it works for you too. |
| cure for the brake banshee girlfriend | victorthewombat
Sep 12, 2002 4:25 PM | | take each pad and with a razor slice off a teeny bit to present a leading edge on the pad as it contacts the rim. Just should do the trick and assumes the pad are already parallel to the rim surface.
let me know. Victor |
