As above if possible ? my dad has a citroen dispatch 1.9d on a xreg (01) . i have just done a service and replaced front brake discs and pads . once in the van started to pump brake pedal which was pumping up nice and hard then a thud and nothing - no pedal ?
Had similar problem last year after his mot was done and passed the brake pedal was soft and spongy just like the master was on its way out but soon came back ! wasnt like it before mot ?
Had a good look today and its as though the pedal is not connected to anything ! so i removed master cylinder to see if the rod inside the servo was moving when you pressed the brake pedal which it is ? also removed the rubber cover on the bulkhead to see that back of the pedal mechanism which all looks fine exept for a lot of free play which is adjustable on the rod (the pedal connects to a rod which then tavels in a tube across to the servo) . i then held an extension bar on the rod that sits in the servo to give it pressure and got my dad to see if there is a pedal at all which there was , so as far as im concerned nothing seems to have broken in the rod to pedal area .
I then fitted a new master and bled the system with plenty of fluid coming from each nipple . had a brake pedal but loads of free play in the pedal before it does anything ? start the van up and just a hard pedal right at the bottom of its travel , try moving the van and applying the brake and nothing just a hardish pedal right at the end of its travel ? removed pipe from vacumn pump and its sucking , refit and remove pipe from servo and its sucking and also looses its presure when i pulled the pipe out from servo ?
Has any one come across this problem before or could it be the servo ? i cant see why changing discs and pads would create a servo problem ? or has something in the rod to servo side broken ? i have never had one of these apart before and you cant even access behind the servo unless you remove it all !!!
Im hoping someone has had a similar problem or there is a common fault with the pedal set up as its similar to the fiat scudo , peugeot expert and its now doing my head in !! he needs it for work and i need it of my ramp !!
I know this forum is normaly for engine managment issues but im lost and thought i would ask as im sure these is a citroen expert on here !! many thanks
