Front Disc brake noisy

[glasgowcyclist]

Are your front and rear discs interchangeable? If so, swap them round (giving the current front one a good clean first) and see if the noise moves to the rear or stays at the front. If it stays at the front then I’d suspect a tiny leak from the caliper.

I know you’ve found no evidence of a leak but I had the same persistent problem appear suddenly and nothing fixed it until I replaced the front caliper.

Looks like the only solution left is a new caliper although you might try Glasgow's suggestion first.

Isn't there an issue with some Shimano Calipers weeping fluid?

I put it all back together this morning.

I did notice that the disc was rubbing slightly to one side on rotation.

I’ve fixed that.

I will bed the new pads in properly and re test

They have a habit of doing it. Make sure the hose is tight too.

So put it all back together and followed this park tool bedding in guide.

No nasty noises thankfully.

Time will tell I guess
