1. I believe I have warped the front disc break, here's a youtube

lol... yup... I believe so too

Buy another rotor, and fit it using the torx bolts that's on your current rotor. Just remember to buy the same size rotor!

I mean exactly that, there is a little bit of play in that.

Its been about 16 years since i have done any maintenance on a bike other than changing an innertube, but i am quite hands on and like to do things myself if i can.

Nothing seems to be rusted on the bike at all, i can remove the allen bolt that goes down the centre of the neck but nothing moves at all?

Ah, that's a bit more tricky unfortunately and could be a few things.
When you say there is play in it, does your handlebar kinda wiggle about ?

Your rotor disk is the spinny silver wheel thingy attached to the wheel.
Your brakes clamp onto this to brake.

Yours is very fubar and is in need of replacing as you wont be able to get that straight again.

The spinny silver wheel thingy is attached to your wheel's hub - the thingy in the middle of the wheel, holding the whole shebang together

It's just screwed to it, by little torx bolts. Take the wheel off and undo these bolts to remove/replace

If you hold the front brake and rock the bike forward and backward by the handle bars do you get movement where the short arrow points to?

aaah thank you, should I replace both of them if I'm replacing one, seems sensible to me? and do they need to be exactly the same, or just the same diameter, also I have managed to sort out the links on the other page, any more suggestions?? thanks :)

You only need the one if the other is ok. You pictures are a little confusing not sure what it is you are asking advice on :confused:

sorry didn't explain, I was just wondering if there were any more suggestions to any improvements I could make on the bike, as I'm going to need to take the wheel off, is there anything else worth changing while I'm doing it

Nah, seems all you need to do is change the one rotor - as long as it's the same circumference, you wont need any adapters etc.

You could alternatively go to a shop in Esher, called "Freeborn" .
The mechanic there - Rob Cole -is a very helpful chap and will sort you out quickly, without over charging.

ps: make sure you dont pull your brakes when the wheel is off, because your brakepads will get close to one another and you might struggle slidindg your wheel inbetween the gap

ichabod crane · 14 Jun 2010 at 16:10

unless your finding anything problematic on the bike everything looks fine, you could remove the reflectors from the pedals

and if you wanted some grippier pedals get some flats.

No noticeable play at the top of the Headtube, but at the bottom there is a couple of mm's of play there.

And i first noticed it when holding the front brake on as described by ichabod.

I suspect this relates to not being able to raise the handle bars too.

Supercow · 14 Jun 2010 at 16:19

icysniper - actually, come to think of it - if the bike has been ridden like that for a while, maybe you need to replace your brakepad. Check if it's worn more on on side than the other - just peek through the "cleft" (teehee) in the brake caliper.

zootfloot, how do you mean you can't raise your handlebars?

I actually brought the bike from there, so I'll be going up there tomorrow and will get a new disc, if I can find the right sized torx thingy to remove the metal thing from the wheel, as I can't atm :(

hmm yeh may remove them and look at some new pedals :)

don't think it has, as I would have noticed it yesterday, but then it could have been like that for quite a while, so how can I tell if the brakepad is actually worn away?? just by looking at it lol?? sorry I really am quite dumb when it comes to bikes :(

Supercow · 14 Jun 2010 at 16:28

Yea you will just see it.
If you are at Esher, just let Rob (bald chatty fella )show you how he changed it over and how to look for brakepad wear, but I'm sure you don't have any

Exactly as i say, i have loosened the bolt but am unable to get the handlebars to rise at all, no give whatsoever. :confused:

I think we need a picture

maybe a silly question but have you loosened the stem bolts?

have a nose here, should make a bit more sense (you have a threadless headset from the sounds of it)

, have just checked the breakpads and can't tell, so am being a noob again and here are some images

Supercow · 14 Jun 2010 at 16:50

The look fine to me

It's the square things inside the cleft
