11mm vs 12mm handbremspumpe performance

[FurlanPx]

Hi I'm going to buy a full hydraulic pump for disk brake grimeca... I found a 11mm pump (like the one on worb5 website) at 10 euro, so I want to buy it...the alternative would be the px 98 12mm pump...but it costs 60/70 euro... so the difference in braking performance between these two pumps is big? (50 euro of difference in prise :O )

cheers

the smaller the diameter of the cylinder of the pump, the more force can be applied to the brake pads.

If the 11mm pump is ok, go for it, you should be able to do stoppies using only 2 fingers.

OK yes I know, smallar the diameter, bigger the force has to be applied, but I didn't know how much "force applied" differences 11 and 12mm . So I go for the 11mm, ..another fast question, I have 16mm axe, and not 20mm, what do you think if I do stoppies.. it doesn't broke I hope ..what do you think?
