So had a good ride with the misses today around the Woburn area through the woods etc but noticed the front brake lever was a little sticky/slow on the return.
Upon our return I gave the bikes a quick wash and thought I’d grease the pistons with silicon grease (the one recommended by hope). As I was pumping the brake lever to get the pistons out I must have done one push too much and one of the pistons fell out along with a brake fluid. Oh balls (or words to that affect). Then a quick drive to Halfords for dot 5-1 before a re-assemble and full bleed. I wasn’t expecting to have to do that to my m4’s when they are only 4 months old lol.

And to top it all of a span the week and then got my finger caught in the brake disk slicing the top of my finger off, perfect!!!!
