[Closed] Brakes howling and poor stopping power. Long term problem.

This is becoming something of a crisis now. My brakes have had this problem since May and I've tried everything to fix it and nothing has worked. I've tried cleaning the pads & discs. Heating and sanding the pads then cleaning them. I've tried changing the pads several times. Buying new pads and throwing the old ones away. I've tried sintered, semi-metallic, kevlar, seeing if it made a difference. Cleaning the discs every time I changed the pads. The result was always the same, brakes were okay for the first ride or two, then gradually back to the usual poor performance. I've also had the brakes bled by a mechanic recently. I can still ride down descents but at half the speed I should be going due to the brakes being poor. The discs were fairly new at the time and are nowhere near worn out now. It has ruined the descents this Summer and has cost me a lot of money constantly buying new pads in attempts to fix the problem. Is there anything else that I've not tried that might be able to solve this stubborn problem? The brakes are Shimano Deore M615.

I've found a small UK-based company who make a rebuild kit for these brakes. I've ordered one, so we'll see how that goes. It's quite expensive, but hopefully worth it...

😆 great find!

Same issue here on my rear 3 year old Deore 615m. Funnily the howling is only when coasting. Tried all the usual solutions so a new caliper turned up today for £24 including pads, bleed block and spacers. Think that would buy one screw on a set of Hopes 😀
