    This presentation by Bruce Goldsmith, and related follow-up by Malin Lobb, explains why flying with 10% brake on a paraglider reduces the pitch stability of the wing.

    I have bin flying PS since 1989 , and never even once , considered what a bit of break would

    do ; other than increase cell pressure a bit .

    Hi Bille.
    From PGT > Dealing with Turbulence

    Wing pressurisation myth. Pressure inside the wing is only dependent on airspeed, so braking and slowing down the wing, will decrease the wing’s internal pressure.

    Braking has other effects and benefits, but people often oversimplify and incorrectly assume it is from increased internal pressure. The myth lives on.
