Front brake sound (howling)
i undestrand, that this wont be easy to identify, but maybe somebody can help me understanding the cause of howling front brakes. (Rebel 450 87')
It appeared after few rides after changing brake pads to new ones. Thought that it could be brakes or front axle or bearings.
Driving on the road it dissapears only if i press the brake handle slightly. After stoping it howls even on pushing the bike forward. Going backwards it gives no sound.
I suspect, that the new wider brake pads just don't release the brake disc enougth.
Tryed to reassebmle ant clean the brake calipers and cylinders. Found that the inside caliper metal plate small teeth, that keep the bottom of outer brake pad were bend. So the outer caliper could be a little loose and after braking just being stuck in slightly angled possition, for the sound to appear.
Bend them back, but the sound is still there.
Actually it was hard to mount the brake caliper back. It is made of two parts - one monting element at the fork, and the caliper itself. They are connected by two bolds with rubber spacers. Is it kind of caliper depth regulator? as on other models i see it is moving freely in that place.
Maybe because of it caliper stays a little bit angled to the brake disk, thats where the sound comes from? Can caliper be adjusted regarding brake pads wear, or it adjusts itself?
And also i was able to push cylinders back inside caliper only with lots of preasure on them. Should it be this way?
