Title: Dti brake pedal suddenly went straight to floor.
Post by: omegadti 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?

Post by: Big Sye on 11 March 2009, 22:18:24: 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.

Post by: Andy B on 11 March 2009, 23:22:48: 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.

Post by: omegadti on 16 March 2009, 20:21:35: 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.
