I quite like it when things squeek!
Others find it irritating - I find their reactions amuzing though; I can pretty much put up with any background noise though.
To clean the rotors, try kitchen paper (or loo roll!) & lighter fluid (most corner shops sell this alongside the death sticks. I've heard Coke does a good job too.
how do i check for this play in the wheel bearings and cones??
not sure what they all are tbh..
and its definatly illegal here for dirt 😉 not in my house anyways hehe
lol tato no she didnt poo, she put the bins out 😉 good girl
Rock the rear wheel side to side. If there is movement then you have play in the bearings and may need cones tightening or new bearings if its a cartridge jobby.
er ok. well the shop has it and they called! they think i need new pads and rotor! it cant be as ichanged them front to rear and still had the problem!!!!!
or am i wrong in thinking this?
So you didn't try the copper slip then?
copperslip is like trying to find copperslip in austria 😉
i couldnt find it before i had to go to work and dropped bike in to shop on the way past
Fair enough - I'm pretty sure it'll solve the problem though. Gotta be worth a try before dropping £s on new pads and rotors. If you want some, drop me an email with your address and I'll pop a sachet in the post (my colour co-ordinated valve cap fetish means that I have several spare packs as they always pop a sachet in with each set).
so i just got by bike back from another shop. they tell me they have nothing but problems with hayes in particular my brake version ryde.
they put the softest pad in and changed back to 185mm rotor and it still makes the same problems!
the installed everything and still makes the noise.
argh!!!
maybe new brakes are needed instead!
callipers not straight?
have the mounts been faced?
Just buy car brake cleaner - lots and lots cheaper than bike specific stuff - also great for degreasing everything else, and if you are bored putting on a rag to knock out your neighbours and then kidnap them.
Do not know about the squealing but DO NOT USE CAR BRAKE CLEANER! It leaves an oily residue and will require new pads. Trust me, I know - I've done it twice or three times... D'oh.
Interesting, the stuff I use doesn't. It does however pull off all the oil on my bike and deposit it on the nice light paving slabs outside the door, which I then have to explain to the missus why there is a big dirty patch out there.
Last time I used it and I couldn't be chewed with the can spraying everywhere I used a tin piercer thing (for condendsed milk) to puncture the can, carefully, before putting it into a brown glass jar for storage. I was then able to use it in a controlled manner with a toothbrush without lots of spray going everywhere
The video of your bike sounds very similar to a problem I had with my Giant XTC C1 carbon/Avid 7s. As soon as the pads were bedded in and started to bite the bike turned into a Vuvuzela and would vibrate to so bad it was hard to sit down/hold the bars.
I did all the usual things copper-slip on the backs of the pads, de-glazed pads, chamfered leading edge of pads, bead blasted the rotor and even replaced the rotor and pads. No change.
Then it occurred to me that the problem was not that the brake was vibrating but that the vibration was at the resonant frequency of the rear triangle of the frame.
So to change the harmonics of the frame I bolted a small stack of 10mm washers (40ish grams)to the redundant V-brake mount on the left hand seat stay.
SORTED - no noise or vibration.
If you don't have V-brake mounts a folded up inner tube cable tied to the seat stay works just as well. As a more permanent solution I intend to make a seat stay mount for my CO2 canister to avoid adding unnecessary weight.
Hope this helps.
beatamax, can you send me a picture i dont really understand fully, sorry.
Betamax, thats the most ludicrous but possibly by some far reach of the imagination still true thing ive heard in a long time.
so ok, i received the copper slip!! thanks ever so much for that.
i tried it and was better but still has not eliminated the problem. i booked my bike in for it first service inspection after 2 months of having it. i told the shop of the problem again.
they serviced the bike and check all. but they dont no why it makes the noise or what causes the vibration problems!
they say they dont no what now and left it like that!?
i said yes so what now, they said they dont no!
whats the next step?
not sure what to do
New pads clean and sand the discs and set the calipers up as in the hope video - then bed them in again
all done.. from my self and the shop, now also have softer compound brake pads too.
where is this hope video for setting the calipers up?
