Brake pedal creep - Kippermcflipper - 6:th-May-2017
Just a query those of you with a diesel astra j (mine is a 2.0 auto) have you noticed brake pedal creep where if you sit with the engine running - press the pedal down hard and constantly - do you find slowly the pedal drops to the floor?
I have heard all about vacuum depletion of diesels but as I have never seen this before I was wondering if this was a common characteristic of these cars or I have a servo/ master cylinder problem

Can't say I've noticed on mine

probably caused by a small vacuum leak in the servo system

Pedal creep is normal with diesel cars. My 2.0 CDTi also does it.

With the engine off, and the brake pedal pressed a few times, it should then be solid and not creep to the floor if all is ok.

So quite right - the dealer checked it over said it was normal. Apparently it is due to excessive vacuum pulling the pedal down and you'd never have this type of effect in real life. Thanks to all for the responses. Apparently it's apparent on all vauxhall cars since like 2005 odd.
