Further to my previous thread...

Need a bit of advice here. I changed the driver's side rear caliper on my 2006 V50 2.0d today. The handbrake mechanism had seized.

The caliper went on with no fuss at all. It was an after market part, but produced by a brake specialist and was exactly the same as the original part. We only lost a few drops of brake fluid between removing the old caliper and fitting the new one. The pads fit perfectly and the whole brake was rebuilt correctly.

We bled the new caliper (twice) and seemed to have gotten all the air out of it, but now the pedal is soft when driving. On the first press of the pedal it travels way too far, then firms up on the second and subsequent pumps. Kind of like how it does with the engine off.

Is there any need to bleed all 4 corners when changing one caliper?

Anyone got any ideas what the problem might be here?

I think we've just managed to mess up the brake bleed, but thought someone might have some experience of similar problems.

If you are satisfied you have bled the line Ok, check that any spring sets are fitted correctly, so they are holding the pads properly.
