Hi.
I freed up and copper greased my mate's pads all round his '97 1.9 TDI but the nearside rear caliper piston only moves using the handbrake lever. I checked to see if foot pedal pressure forced brake fluid to the piston but it didn't. I was able to remove the bleed valve completely with no sign of fluid while he had his foot hard down on the pedal. The offside rear works fine. Can this be due to the load sensing pressure regulator valve ? Has anyone else had a similar problem on just one side ? Is it serviceable. Or is there something else causing this ?
Thanks !

Could be flexi pipe, damaged brake line or valve. Can you wind calliper back?

As above.
Slacken off the line as it come into the caliper gentle press on pedal and see if fluid comes through. Be careful you dont want the fluid on your pads.
