Do your bike’s brakes need a bleed?
Dirty brake fluid
Like many staff in bike shops we like our coffee and cakes but what we don’t like to see is brake fluid looking like a good mug of black coffee. We much prefer the fluid in a Shimano system to look like Ribena.
That one of the jobs that people often forget to do is get their local bike shop to bleed the brake and replace the brake flued.
