Brakes binding.
Posted: Thu Feb 27, 2020 11:59 am
I'm a little embarrassed to post this but it might help others so......
I upgraded the front brake pads to sintered on my Euro 4 Classic. Everything seemed fine until the brakes warmed up and then they started binding quite badly. Thinking I'd done something wrong on reassemble, I stripped it down again but couldn't find a problem and the binding was still there. Finally put the old pads back and the problem disappeared.
I was beginning to think it was something to do with the ABS (which I don't understand very well)
After much messing about I finally measured the new pads and found they were slightly thicker than the originals.
I then did what I should have done in the first place and checked the master cylinder. Yes, RE had overfilled it! I certainly haven't touched it.
The slightly thicker pads only just cleared the rotor when retracted but when the fluid warmed up there was nowhere for the excess to escape to as the reservoir was locked up.
Took me a LOT longer than it should have done as "it's a new machine, it can't have been assembled wrong" thinking took over. A drop of fluid removed from the reservoir and all is well.
You'd think I'd know better at my age
