Squeaky Hydraulic Disc Brakes
I currently have a Scott Aspect 20 2010 which I bought second hand. It was all checked and serviced.
After about a week of riding the brakes developed a rather loud squeaking, similar to the sound of a foghorn going off. I tried sanding the brake pads down, but that didn't work. I replaced the brake pads and for about a week the squeaking stopped (they were resin pads). I tried cleaning the rotors with an alcohol based solution, that didn't work. I have just bought replacement rotors but again that hasn't helped. Braking hard is okay, the squeaking starts when my speed is relatively slow, but is alright when breaking from speed.
Can anyone offer any suggestions? The only thing I haven't done is replace the fluid in the brakes themselves, but I doubt this would do anything.
Thanks in advance
The brakes I have are Shimano Hydraulic BR-M486
