G'day zacc

I just went through the mitsu service manual.

Sorry but everything is pointing to the Master/ Pump itself..

if all relays are ok, and there are no loose connections anywhere.
the abs computer is still throwing codes, so that is ok.

i can tell you that Mitsu has sold more than 40 in the last 12 months

@ $2200.00 though i'd have a real close look at all wiring first

yeh thanks for the guys , it is pointing towards the master cylinder. just replaced the accumilator ( lucky i could get it at trade) , checked all the wiring, even bled the brakes . at $2200 bucks i will certanly looking to see if i can put new seals in it . when the lights come on now before i start it i hit the brake a few times to release some pressure , turn the key on , alarm sounds , pump turns on pressure up lights off and away i go . i think i will be buying a $30.00 anchor and a snatch strap put it all on the wifes side and use that if all else fails . cheers
