I currently own a 307sw (57) 1.6 petrol 110 SE. my issue is the rear right hand side brake does not touch the disc. I have changed the pads and calliper but still no sign of the pads touching the disc. Brakes work fine on the other 3 wheels. Any advice would be greatly received. Thanks in advance

Sounds odd?? are you saying that with the brake pedal pressed you can still turn the R/R/H wheel?
Does the hand brake work on both wheels? When bleeding the brakes did you get a good squirt of fluid from the new caliper?
I`m thinking the flexible brake hose has collapsed internally preventing brake fluid pressure to the caliper.

I had a garage replace the calliper so I couldn't say about the squirting. I know when I replaced the pads and it was jacked up, pressing the brake pedal stopped the wheel however now I look at the rear right disc after driving and it looks like I've left the car for a few days in the rain. It has corrosion on the disc!! I may have to phone the garage back. Thank you very much for your reply. I will look into the brake lines

If a garage has replaced a caliper and the brake is not working I would suggest you take it straight back and complain.You have paid them to sort your brakes and the car has been returned with a safety issue?? not good!!

Caliper slides corroded inside maybe. Debris dropped in the caliper pipe union stopping fluid pass though or they've clamped the hose too tight and buggered it. Take it back though.

3 scenarios be considering - piston somehow seized, mounting guide pins seized if it has them, or some kind or problem with the load compensating valve.
I did once encounter a car with a similar problem. After much head scratching we discovered the flexibility oppress disintegrating, and the flaky debris inside it was acting almost like a valve and not relieving the pressure, not allowing the piston to withdraw. It's extremely remote chance but if all else fails the cause could be similar.
