Righto chaps, thanks for the replies on this.
I bought a new master cylinder (Lucas one), fitted it and bled the brakes through. One of the rear bleed nipples gave up during bleeding so I bought 2 new rear calipers and fitted those too.
I've re-bled the brakes countless times but the pedal travel is still way more than it used to be, my leg is well stretched out when i'm pushing it down.
The real point for me is that the front pads are still loose in the calipers. I'd say theres between 0.5mm and 1mm on both sides. I can jiggle them around in the caliper. When the pedal is pushed down the pads are locked onto the disc and the pedal is hard, doesn't sink with time.
What ever could be causing this???
I so need to get this sorted so I can use the car again.
Cheers, Ian
