got a bit of a problem with my brake on series 2, the pedel travels quite far and doesnt seem to want to stop, i have changed front discs and pads, but now stuck, could it be brake servo unit? or air in the system

 

Fooked Master Cylinder possibly. This will lead to the next issue of the replacement 25.4mm Master Cylinders being unavailable any more.

 

you can get the cylinders from brakes internationl in rochadale.

 

would try bleeding it first and making sure the rear wheel clyinders aint leaking
