I’ve gone back to the original master cylinder as I simply could not get on with the lever feel the Blackbird MC gave me. It was a little too vague, despite the power being OK.
However, I still wasn’t happy with the initial bite and lever effort for braking effect of the original.
Yesterday, I decided to take my own advice and give the pistons a good clean and grease with red rubber grease.
It already has Brembo HH pads on Brembo discs so no issues there.
The pistons didn’t look bad, but there was some crud there to be gotten rid of.
I liberally applied Castrol Red Rubber grease and worked the pistons in and out a few times to ensure all is well distributed.
This morning’s commute gave me a good chance to test the brakes under varied conditions and the difference is significant. That initial bite is vastly improved, and the braking effect for lever effort seems to be improved too. While the pistons didn’t seem seized by any means, the clean and grease has definitely been effective.
Along with chain cleaning and lubing, this will now be a regular maintenance task.
