Difference between PK brakes and Prim brakes

[keuk]

Hi !

I have often read that pk rear brakes are better than primavera/Et3/special brakes, but is it really true ?

I have compared both and the brakes pads have the same width, the only thing that is different is the pad axis, on pk the distance is bigger between the two axis.

Does this difference make a better braking ?

Cheers

Hi there,

yes there is a big difference between both breakes. The PK works much better that the one from PV/V50/... because it's a complete different constuction. Take a look at the whole brake (especially the arm where the bowden cable is fitted), not just the pads and you will see the difference

@ Paichi :

We´re talking about the rear brake, not fork right ???

I couldn´t recognize a differance between pk and v50/pv brake both work fine ! ( i am not refering to the constructing, just function )

Oups... ok so forget about what I've said ;)

So there is no big difference between the two rear models.

Rear brakes are the same as far as I can see. I?ve never heard that One is better than the other.

The front brake on a PK is much better than the PV as Paichi mentioned the Geometry of a PK is totally different than a PV.
