I have a 1998 ( s ) vauxhall astra 1.7 diesel ( low blow engine ) the brake pedal is hard but the car still stop`s with a little bit more pressure on the brake pedal ,
i have disconnected the pipe off the vacum pump and it is sucking in air so in theory i would think that it is ok ,
I have also disconnected the pipe comming from the servo and when i do this the pedal go`s hard so there is no movement and the car will not stop , when re-connected the pedal has a bit of give and the car stop`s as at the beginning of the question ,so in theory the servo is ok .
Is there a way of checking the abs pump ?
Where is it located ?
any other idea`s what it may be ?
Any help is gratefull .
Thanks in advance for any help !

Hi I drive a 98 astra estate .The problem is in the brake reservoir the model in question is prone to this problem .The seals have turned back to front .This happens when the bleed nipples are not opened when new pads are fitted or not bled correctly.hope this helps

Your brakes could have siezed, its more of a complicated job for you, as you have to get to the back, which is awkward, but you need that servo pipe on, as the brakes will stay hard, and its not worth taking a chance. Run it to the nearest garage, they wont charge you for having a look, and it will eliminate any unneccessary messing about.

Your vacuum pump diapham has a split in it lowering the vacuum. you can buy the diapham separate try millfield auto spares Peterborough they do a postal sevice it is easy to change just undo the ring of screws on the outer rim . you can find the pump by following the vacuam pipe from the servo back

I know to check your servo,before you start the car press the brake peddle down,then start the car,with your foot still on the peddle you should feel it go down a bit.Dont think it would be your abs,but i would check all your wheel callipers,just to make sure everything is ok there.Hope you sort it out.

If you look on the bulk head under the bonnet you will see a stiff vacume pipe going into it.That goes to the polen filter witch is under the cover under the wipers(where the heater motor is)the most common fault is that pipe has come out under there and you loose vacume to the breaks you will see a small pipe where it pushes back into.Hope this helps if you get stuck call me 07783227565 i will guide you through it.

doesn't sound like the ABS pump to me.. sounds like you have a vaccum leak... are your pads ok too? i suggest taking to a garage to have a diognstic run
