another thing that is not unheard of is bad flex hose(s)

they can swell internally(usually at the metal fitting at the ends)
swell due to rust from fittings....when uapply the brakes, there is enuff pressure to force the fluid through the line and operate the brake
but when u release the pedal, the return pressure is slight(actually non-existant, the driver has merely released the pressure being applied)
the fluid then cannot easily get released and causes the brake to still have pressure applied.....

on an awd car, this in effect slows all 4 wheels (i know, not EXACTLY accurate, but ....) and makes the whole car seem like its fetching up...

i have seen this on the rear of a fwd car to the point where the rear wheel is locked tight and WONT release....

japanese cv joints are of a slightly diff design than most n american ones (dunno 'bout european)

they almost NEVER break...i have changed axles where the joints WONT flex in any way and can be thrown through the air only to spear into the ground and STILL not bend/flex...

and they STILL had little appreciable binding felt in their action when still in the car....
