Not had much look over at vauxhall forums so decided to pop over here being an x mv6 owner
Right so I switched to the 1.7 DTI, as I like the 600 miles between fill ups and not the 200 lol.
Anyway, got a brake fault!
Will try and give you a quick line of events...
When braking the brake pedal goes hard, the car still stops but it is as if the rear brakes are only working.
If you pump the pedal with the car off and switch it on the pedal sinks to the bottom.
I have replaced the master cylinder as it was full of poo (genuine part) and its still the same.
Brake fluid change (when bleeding the pedal sinks nicely to the bottom as it should, when all nipped up the pedal goes hard again).
Prior to changing the master cylinder I had it brake checked at work and the front brakes where not working, after replacing the master cylinder the brakes worked (passed an m.o.t and random free kwik fit brake check) but the pedal is still hard, and by christ you have to stand on the pedal. Both the m.o.t'er and kwik fit man commented on the brake pedal but said it passed.
Prior to the pedal going hard it was an intermittent going hard fault but now it is permanently hard.
Someone has said that the front brakes have seized, but i find this hard to believe that they would both seize together.
Occasionally when slowing down on a slip road, i.e. gradual braking they feel like the want to grab and work properly.
Occasionally the abs light comes on but will reset if turned on and off (pedal hard either way).
Any suggestions?
