I have a bike with Ultegra Di2 with rim brakes. The rear brake lever is not snappy any more, I do not have a better word to describe it but even if the bike is braking alright the lever feels kind of hard.
All the LBS are saturated its incredible how their workload is so high in my area they are giving appointments months in the future so I want to try to repair it by myself.
What is according to you guys the issue, should changing the brake cable be enough? In case it is how complex is it to do at home?
