Got a issue with excessive brake pedal travel sling with a hissing sound on my 2007 Renault master. I've checked all discs/pads which are ok, replaced the fluid but still I get a lot of travel when applying hard pressure on the pedal. I've had it on some brake rollers and they do work sufficiently to pass an Mot but I just have no confidence in them at presence, sometimes they feel worse than others.
Im thinking it maybe the master cylinder but why would it vary sometimes?
