Caliper Seals

[gerrythom]

I have just replaced my rear brake pads and cleaned the corrosion from the back of the caliper and the suspension arm. The caliper split into the two halves. I have put everything together again and when trying to bleed the system the brake fluid is escaping from the top end of the caliper. Should there be a rubber ring seal between the small holes on the top part of the caliper where the two halves meet? I think I may have lost it when dismantling the caliper.

Welcome to the forum.

 

Yes, there are seals between the 2 halves. Before removing the bolts holding the calipers to the suspension arm and after removing the brake pads, the pad cover retaining bolt should be put back and done up so the 2 halves stay together. The seals are Citroen part number 444205 and you will probably need to get them from a Citroen dealer. On the C5 Problems and Fixes section there is  a pinned topic on cleaning the rear brakes which might be of use http://www.citroen-owners-club.co.uk/citroen/topic/6881-removal-of-rear-brake-calipers-pad-replacement-c5-to-2008/ There are also topics covering the front brakes.
