Front brake is semi on all the time

Hey guys, Iv started to notice my bike getting "heavyer" the last month o two. Checked today and the front wheel wont spin freely (should it?) it has to be pushed - not too hard but pretty hard.


I guess its the brake as i can hear the disk scratching as I turn the wheel. I can still see the wear lines both sides of the brake so I dont really know why its so stiff..


Do I need to bleed the brake??

Thanks

no, but you need to clean the pistons on the caliper, as they aren't retracting. depending on when the brake fliud was last changed this may need doing also (2 years) but not for this problem.


if you remove the caliper from the fork leg, and press the lever, it will pump the pads out a short way, leave the pads in, then give the chrome pistons (these are behind the pad/s) a clean with a toothbrush and the push the pistons back in with a G-Clamp so that you can get the pads back over the disc, then pump the brake lever a few times and see how you get on. if you have a haynes manual then have a read of it, probably give you a better idea..


if this doesn't work you may need to overhaul the caliper, again see haynes manual

I did what you said, couldnt get behind the pistons to clean the other side but got most of them. Work much better now :D


But I can still hear the same metal on metal noise... I think maybe its the bearings..

hahahahah

you'll not get to the back of the piston, cause that emans its out and you've got fluid all over the place, hence leaving the pads in.


you need to remove the pads and apply some coppaslip/copperease to the backs of the pads, they are moving on the pistsons hence the metal on metal noise,


NOTE THE BACK, NOT THE FRONT!!! otherwise you've applied grease to the braking surfaces and you won't stop
