Hard to pull brakes

[GlenBen]

So, I just fitted some 105 rim brakes to replace some not so great tektro ones. Since fitting the front is 10x better but the rear is incredibly hard to pull. It springs back open fine, its just hard to squuze the lever.

Any ideas? Im stumped.

Is the cable run reasonably smooth? Did you install the cable in the shifter correctly? Was it hard to pull before? I always put grease on my cables prior to inserting them.

Runs smooth, when i disconnect the brake, the cable moves easily enough. Think its installed in the shifter ok, maybe ill take it out and try again.

Before it was easy to pull but didnt spring back very well.
