Front Wheel problems
Hi,
Just bought a new giant escape disc. Was ok at the start but now the front wheel is giving me a lot of sounds. First the front wheel gives off a humming sound if i move the bicycle slightly second is that the front wheel will give off rhytamatic click or squeals sound during cycling.
Help? Any idea what is wrong?
Thanks

Pick up bike front and give the wheel a spin. You should be able to locate the source of the problem. If not return to the shop where you got it.

I wonder if the humming is a very slight pad/disk rub, at speed it gets lost in the back round but when slow and otherwise quiet able to be heard/felt.
Clicks are a far different noise then a squeal. Clicks are often from bearings or spokes although a metal stemmed valve can wag back and forth and click against the rim hole. Squeals on new wheels can be the "rubber" dust cover (where the axle extends from the hub) rubbing on their seats or on the cone/spacers. A tiny drop of lube on the dust cover ends will change this.

thanks!. I tried adjusting the calipers position and only succeeded in over torquing the screw and breaking off the head. Managed to extract the broken screw and i am back at the bloody disc rubbing against the brake pads. Really wonder if this is a warranty issue that i can raise.

Sounds like you should take it to the bike shop where you got it. You mentioned that it is a new bike. That is the purpose of dealing with the local bike shop.

The solution, in my case was TRP Spyre calipers, with sintered (semi-metallic) pads, a 180mm RT99 Icetech rotor & post mounts with conical washers to allow proper caliper alignment relative to the rotor.
Not saying heat warp is specifically your issue, but if it is, a step up in system capacity certainly wouldn't hurt. I've never known a centerlock Icetech to warp. I have known a 6-bolt Icetech to warp, but it flatened out as soon as it cooled.
Many of my brakes get hot enough to discolor blue/brown. Rain sizzles & sometimes I can smell them...so maybe I push them harder than some? I dunno. But I do know OEM brakes usually aren't up to par if you ride agressively & are heavy. as is the case for me.
I'm sure at this point the rest of the thread will be about a complete upgrade to TRP HY/RD or hydraulics or some such hollaballoo in your brand new bike. That's just extra cost, complications, & maintenance. Plain Spyres & 180mm Icetech rotors will get you sorted.
