front disc brakes dragging

Has anyone ever had this problem?I have made sure the breather on the fluid resevoir is unblocked.Is there anything else other than loosening the wheel bearing a little?
cheers

yep, caliper could be siezed, and more commonly the brake hose has collased internally and not allowing fluid back to the master cylinder. crack the bleed nipple. if the wheel frees up and a bit of fluid squirts out then this is your problem.

I have recently replaced brake lines with braided stainless ones so it might be the caliper.It has siezed up before.

has this problem happened only since replacing the brake hoses? Are they the ADR compliant ones?

Yeah they are adr approved.Very well made.This problem was there before that.I dissasembled the caliper and put new o rings in them,removed the pistons and cleaned it all up.The worked great till a couple a days ago.It was parked in the sun all day(work) and i noticed strait away they were dragging and the pedal had no play at all.

If the brake pedal has no play, the master cylinder push rod is probably adjusted wrong, back it off a bit so there is a bit of free play before the rod pushes the master cylinder.
This will make your brakes drag if not right.

yep, I agree. Also peel back the dust boot around the pushrod and make sure the circlip has not broken.

Thanks guys,I backed the master clyinder pushrod off a little and it seems to have done the trick.She passed rego inspection for another year.The brake test only said 75% though.I was expecting more as it feels very firm and you can lock the wheels up if you want to.
Thanks Secoh and Menangler for your wisdom.
