Dti brake pedal suddenly went straight to floor.
« on: 11 March 2009, 22:10:53 »

Was out in my 2002 2.2dti and put my foot on brakes when stationary, the pedal went slowly to floor - felt like a seal had suddenly gone.   Has anyone else had this and can give me some pointers for a quick/economic fix?

i would think you have a leak in the system somewhere. check level,  if that ok.  try and trace through where all hoses etc lead to.

I'd go for Alf suggestion of the master cylinder too. You'd need two leaks on a split circuit brake system for the pedal to go to the floor.

Had the seals go on the master cylinder in the Pontiac.  Found out at 80mph traveleing downhill towards a walled round about that they didnt work anymore.

and yes the power of prayer really works as I am still here to talk about it.

just had car looked at - apparently the brake pipe in the middle of the car at the back has sheared off possibly due to rust - so much for dual line brakes.
