greasing the brakes

with everything else that you have to be fussy about, in bike maintenance, i think it;s odd that
it;s more or less ok to drip chain lube on the back wheel rim.

after all, it;s one of the the braking surfaces.

i spray silicone, teflon, etc on the chain all the time, usually it drips onto the wheel rim, yet
it never seems to cause any problems.

no one seems to warn you about it, it doesn;t seem to do anything bad...

yet a car, now a car, you can;t get anything slippery remotely near the brake pads, drums
or discs..

just one thing to be thankful for..

Mud and water make quite a good grinding/cleaning paste. FWIW I clean the rims with methylated
spirits if I think I've dripped oil on them. Once it gets onto the brake pads it's probably going to
stay there.

I would go with "less OK" here. I avoid doing this, but then I don't consider glopping oil on a
dirty chain to be maintenance. Take the chain off to clean and lube.

Well, it is the rear wheel. See all the posts about braking effectiveness. The quickest stop is
achieved with the front wheel, only.

I do not advocate lubricating the braking surface. The beauty of rim brakes is that most stuff on
the rim, including oil, will be washed off in the first rainy ride.

I have an old hub with an old cassette on it that I use when I put on the chain cleaner and re-lube... just pop out the wheel and put in the rimless hub... no lube on the rim, no stains on the tire.

actually i have a way to clean the chain, that i had not read about.

i don;t use oil on it, just silicon and teflon type things.

to clean it, i spray it with 409 or some car engine degreaser.

let it sit for a while.

then really blast it with a high pressure water hose.

100-125psi at least, through a concentrating nozzle.

put the hose right on it, trying to target the inside of the links. i kind of aim mostly into the
cassette but at the chain.

do this for a couple minutes, cranking the chain via the pedals, water blasting everywhere, then
shake and wipe dry.

then maybe some wd 40, then wipe the outside of the chain clean of that.

then some silicone and teflon, wipe outside again, then ready to go.

it seems to work, there is only about .3/16" wear on the one chain that i have exclusively used this
method on, at 2500 miles.

i ride a lot, so there is no question of sitting around rusting, after the water.

sometimes i will ride it a mile or two to get the water out, prior to official lubing.

It's odder than your lack of punctuation..why on earth would anybody oil a

To get rid of the squeal (even at the expense of braking power). I did it a couple times when it
didn't matter... the squeal was that bad.

i've had a mechanic recommend this to me (under his breath in hushed tones) as well for a really
persistent very loud brake screech (squeal doesn't do it justice). i just live with it --
occassionally i let a mechanic have at it .. they all inevitably give up. who needs a bell or
pressurized horn when i got my front brake?

I don't understand that (perhaps you used a huge amount?) because a drop of oil or grease *causes*
squeal!!! In fact that's the only reason I'm ever bothered about accidentally getting oil on the
rims because a _small_ amount seems to actually *improve* braking, weirdly, and it will quickly
disperse anyway.

Degrease rims with methylated spirits or try any of the usual methods (toe-in/change pads, etc) to
get rid of the squeal.

actually i think the point was to make the braking consistently bad. with mine in the wet it would
shudder pretty badly and screech like hell, in dry it would behave reasonably (still some squeal). 2
forks, 5 brakes, 4 pads (including kool stop salmons) and a thorough checkout of the headset a few
times later and ..

the only thing that worked was to "weaken" the braking by pulling the straddle cable way up
(cantilevers) and yes, greasing the pads (a lot). i gathered the point was to make it consistent
rather than grab/release, rinse lather & repeat even if that was consistently bad it was more than
enuf to endo.

please have at it, if you wish. i would dearly love to know.

Accidental overshoot while oiling chain on bike.

Interesting. When I drip chain lube on my rear rim, the brakes squeal horrendously. I have to clean
the rims and brake shoes with solvent to make them shut up.

Nothing _causes_ or _stops_ squeal; you can only _affect_ squeal, or if you're lucky, _toggle_ it.
Any item or method that stops squeal for one person makes it worse for another.

Maybe that works by revitalizing dried out pads?

Ooh, physics. Must be right. That particular book has 500+ pages. You want to suggest where to
look for this?

The greatest braking effectiveness on the front wheel is evidently when it is just lifting the rear
wheel. Front wheels do not skid on clean, level pavement. Now, under those conditions, what good is
it to use the rear brake?
