Good evening!
Working my way round my '9 I found the rear break fluid was like dark syrup and the fronts were only slightly better.
Cleaned out the rears and passed a few master cylinders of fresh oil through and all is great. The fronts were also really bunged up around the pistons, so I gave them a clean too. Using a syringe i pushed new fluid up the lines and it all seems OK. However I can't seem to bleed the bloody things. I have a pipe and one way valve fitted and working on each side i have been extracting bubbles, however i never seem to be able to reach a firm lever - its very spongy, although the front brake is binding.
Any thoughts, hints or tips?
Cheers! Mike
