Curious for some experienced opinions.
I gave my Dad my last bike (GT 29’er) and picked up a Marin Bolinas Ridge last year. I got the Marin tuned up, including a break flush. Due to life I didn’t have a chance to ride it last year and it’s been stored upright in a climate controlled room ever since (spare bedroom at 22°C).
I was hoping to take it out soon and checked the brakes with some disappointment.
The rear brake has no pressure, but also no obvious leaks. Anyone had an experience like this? Any thoughts on where to start the diagnostic?
Any and all help is much appreciated.
