braking problem

[pasco]

Am I reading this correctly? Must be a lunatic.

that you are mate! we were just discussing why anyone would write such a comment!

[warwick hunt]

in responce to gians comment..a lot of vrs owners have always commented about brake pedal going down when pressure kept on..he cant mean brakes in general though.

There is a technical document given out by seat showing that this is normal to the diesel engines due to the way they work.

I can get the document from work if someone wanted me to.

Really dont know why people post things up when they dont really know the answer or dont read the full thread for extra info... Where in the technical doc does it say when the engine is off the pedal will continualy depress to the floor? And diesel creap to my knowledge is really quite slow and depressing the pedal... Op, listen to the people who are telling you theres a problem. Maybe post in the ask a tech section

i have taken it to a garage to have a quick check this afternoon and they agree that it was not correct!

they bled the system from the calipers and then settled on the decision that there was an issue with the master cylinder.

i think my best option would be to either get a master cylinder and get it sorted that way, otherwise get the brakes bled again from the master cylinder and through vagcom on the abs sensor

To be fair. I didn't read the center section of the thread. My fault there!

Although after doing that now, I would look into doing as you say - bleeding the master cylinder first and seeing how you get on.

Half the trouble is knowing how badly its doing the drop to the floor, its hard to see over the internet.

very true, thats why, as good as the internet is and however good the advice can be. things can only be explained in type to a certain extent. i have took it into a garage and they say that it felt like the master cylinder had gone. with all the problems that occurr on these cars i wouldnt mind trying a few of the smaller jobs before having to have a new master cylinder fitted to the car.

if you say theres no leaks etc some times taking the master cylinder off and checking there isnt brake fluid in the servo itself might be an idea saying that this is very rare!

If this was my car id check all pads all round arnt seized and that all the sliders are free also check the rear pistons are in the right position to sit over the pad, re bleed the brake on each corner just to be sure double check your not loosing fliud etc. then clamp of all hoses by brake calipers like already mentioned. id say it the master cylinder but really hard to say with out looking really.

How are you bleeding your brakes for instance ( bleed nipple loose pump say 3 times then on the last one hold pedal to floor tighten bleed nipple foot pedal off? same for all brakes?

the brakes were bled by the garage in the above fashion and also with a pressure bleeder to ensure there was most definitely NO ait in the system. i have checked all pads and obvious stuff like sliders etc and it was none of them. When i went to the garage i was talking to the mechanic there and he said the only other possible thing it could be would have been the master cylinder. There is one more thing to try before i fit a new master cylinder and this is to get a different garage who have vcds to bleed the abs unit and also bleed the system from the master cylinder. the garage i went to did not do this as they said there was no bleed nipple on either the abs unit or on the master cylinder.

This garage must not know what there doing or im missing something,i cant see it being air in the abs pump but i guess its worth ago,There isnt any bleed nipples on the abs pump,

The point of usin vagcom to bleed the brakes is to operate the abs pump while bleeding the brakes in case there is any air trapped in it and you bleed at the calipers! So not sure what the garage is on about lol.

I work in a ford garage and on the mk6 fiesta the abs modules are common to fail...Anyway i have to strip the pump to replace it and the warranty procedures is to connect ids to car and like said works the pump and pressing the pedal like 30 times on each corner..o and we have to do this twice! Its a two man job but this is what the warranty procedure says. Hope this helps so you know what happens! Im not the best at typing what i think lol.
