Clutch problem with KRR-150

[vamr]

It's definitely the front wheel's brake caliper... for some reason it's not fully disengaging and therefore am getting a constant low speed squeak. No idea how to fix it yet... hopefully google will have an answer in store.

Redid the wheel alignment of the back + chain tension... seems pretty good at the moment so I guess that's my silver lining

You could try buy a can of brake clean $10-20.
Take the caliper off clean it thoroughly.
get a g clamp wind it back fully.
Check the brake piston boots and pads if they are not right replace them.
If the pad is unevenly worn that is probably why it is not returning as the piston is continuing to push it after pad is crooked. If that is the case get a straight edge and spin the wheel to check for warps.
if both are intact glean the now exposed bits of boot and piston.
If the boot is not intact do not clean the boot!
Changing the boot is out of scope for me because I have never done one. putting brake clean on a perished boot will make it perish further and can damage the bits inside.

I have only had a bound brake on a bike twice once from a damaged pad, and once from stone under the boot.

In cars i have had them from a:
* warped disk.
* Unevenly worn disk.
* Parked for a year before I bought it.

The pads look alright, the disk has recently been replaced (it's a single) and is true and straight. Is there a return spring that the pad relies on for recoil?

Also, on a random note, has anyone per chance had a misalignment from the front wheel to the headstock? Fully straighted out bars = wheel pointing somewhat to the left.

Sorry if I'm asking too many questions... kind of opened a kettle of fish.

Depends on the brake but generaly they rely on the movement of the disc to return the pad, hence the need for the clamp to return the piston. When they are sprung it is a counter balance not a return.

Your wheel thing isn't misaligned wheel it's misaligned forks. Slacken the wheel mount bolts, and the triple tree bolts , hold the wheel between your legs and twist the bars gently to straighten things up (sometimes you can even do it on a small bike without loosening things). Then retighten things.

If it's been in a stack (you said it had been down) check the bars are straight.
check your alignment based on headstock position not bar position.
If it is your forks not straight check the shock surface for ripples (may have been straightened on the cheap or not even fixed).

My old yamaha had a crook bar. I was sure it was going mad because of the amount of drift to the right. After complaining repeatedly to the shop I bought it off the took the bars off and sat them next to a stock set.
there was a 3cm between left handgrip. no prizes for guessing there was preexisting damage to the crank housing from bing dropped in a driveway.

Thank you for that. Did the trick indeed.


Arg, this is driving me nuts. Now both wheels are squeeking (definately the brakes)!

Looks like I will have a fun day tomorrow taking the brakes apart.

Le Update: All fixed... hoorah to a big rubber mullet!
