C4 2006 Front Brake Pad Replacement.

[jay_uk]

Ive found a couple of guides on youtube

 

Guide 1

 

 

They are both in French and are not the best quality.  One guide seems to show that I need torx sockets and the other show normal socket.  Any idea what I need before I start jacking the car up? It a C4 1.6 Diesel. 

 

Are they any other guides, I can't find any.

 

Thanks

There is a Haynes manual for the C4. http://www.amazon.co.uk/Citroen-Service-Repair-Manual-2004-2010/dp/0857335766/ref=sr_1_1?ie=UTF8&qid=1451770185&sr=8-1&keywords=c4+haynes+manual

 

In it there are 2 makes of caliper, Bosch and Teves, with the Bosch one being on all models apart from the 2.0 hdi. On the Bosch one it shows the caliper lower bolt (hex head) is removed and then the caliper pivoted up so the pads can be removed.  If the pads need replacing then chances are the discs are also worn enough to need replacing and then the caliper carrier will need removing and Haynes shows it uses torx head bolts needing a torx bit to undo. To check on all the bolts you only need to put the steering on full lock one way and then look under the car at the front brakes, it is not necessary to jack the car up and remove a wheel. 

 

Haynes gives the disc thicknesses as:

 

266 mm diameter disc - new 22 mm, minimum 20 mm.

283 and 302 mm diameter discs - new 26 mm, minimum 24 mm.

Also it gives the disc maximum run out 0.05 mm which should be checked when new discs are fitted so that the brakes do not start to judder after being used for some time.
