c5 2.0 hdi 2002... niggles

[eric denyer]

hello all i post in the hope that somebody can answer a couple of niggling questions heres hopeing....

1 engine randomly shuts off when drivers door is opend.... wiered i no

2 aftermarket rear pads.... i had 2 sets from differnt makers and the pad material hangs over the front of the disc by about 3-4mm is this normal?

any help anybody can give will be most welcome ta in hope

[oneday]

the rear pads are probably overhanging the discs because of the caliper to arm corrosion look in the searches there is plenty of info on this subject

[eric denyer]

many thanks for your prompt reply and i should have realised lol any ideas on the intermitent cutting out when door open lol i have read about some cutting out when driving

[oneday]

not sure about that side of things sure one of the electrical boffins will be able to help you with that. or have a lexia session that might tell you something. not sure where you are located. if you look in the supersticky it will tell you where all the people are that have one or if your near here i can do it for you

Rear pads should locate by pin through caliper and pad so they cannot be misaligned and caliper is secured so unless you have pin or bolt missing it must be right.

Some after market linings may come closer to the pin. I trust when you say 2 sets you don't mean different manufacturers pads within a caliper or different sides otherwise dangerous. They may seem fine in normal use but mixing pad suppliers in a caliper or axle can snatch under emergency braking causing a spin which the ESP cannot cater for.

Electrics, fist action is to try a re-set of the BSI by battery disconnection. (see stickys on this site on how to do it. - not just disconnect and reconnect. (30 min job...most of which is standing around clock watching!!

the problem with the rear brake calipers on a c5 is corrosion where the calipers join the rear arm it is a well documented problem it has nothing to do with the fitting of the pads. mine are exactly as you discribe yours and this is the problem with mine.

thanks all michaelh never used differnt pads per axle or mixed them i just paniked and braught another set before realising that there was somat wrong with the calipers so will order bolts and attack them very soon lol wish me luck with getting the old bolts out....

oneday ta will try a bsi reset did look for the super sticky re this but couldnt find it but thats prob just me being old...if that dosnt cure it then i will book it in for a lexia hook up via one of the chaps on here although she has now started to emit a single beep on start up after all the lights go out but with no warning light so spose this may be related.. will keep u all posted

[oneday]

super stickey are on the board index page

[eric denyer]

Hello Eric,

The problem with the brakes has been documented, and is common to Xantias and C5s. It can be resolved, but takes time and care. Unfortunately, as you have a C5, you probably are going to need a blowtorch as Citroen seem to believe that threadlock is a brilliant idea (boy, did they get that wrong! ).

I have had this with both the Xantias I have owned, and all I needed was the right tools and time and care.

I hope that this link helps (even though it is for Xantias). You need to get this done before it gets much worse, as the calipers may get pushed onto the rear disks, which will damage them (expensive). Something I intend to do in the near future is to shape a piece of plastic bottle to fit between the trailing arm and the caliper to act as a gasket and prevent re-occurance of the corrosion. It needs to be thin so as not to unbalance the brakes.

I hope that this link may help with the ECU/BSI issues.
