Hi Stepen M,
The following ids from the UK Pajero
forum;
this post is to warn all
home mechanics about working on your brake system, particularly the 3.2di-d model but may
well be relevant to other models with abs. I had the brake pads changed by my local mechanic on my 2000 model 3.2di-d, a simple enough job, but on the road
test after 100 metres the abs fault light came on and buzzer sounded inside the car!
nothing we could do would cure the fault so it was time to call in our "ace on the inside" Ivor Green at solihull mitsubishi. the only possible solution was to get the car recovered back to his workshops for him to connect up to diagnostic computer! not wanting to
bore you all with loads of trivia I will go straight to the results, "hydraulic brake booster" low pressure switch failed, MOST LIKELY CAUSED BY FLUID BEING PUSHED BACK UP THE SYSTEM WHEN PUSHING PISTONS BACK IN WHEEL CALIPER. Ivor has asked me to let everybody know that the flexi pipes at the caliper should be clamped and the bleed nipple cracked open to release the excess fluid as the pistons are pushed back in the calipers. to make matters worse we removed abs relays with the engine running to stop abs pump running constantly and this caused a voltage spike to render the abs computer unservicable! LESSON FROM THIS IS "DO NOT DISSCONECT ANY THING ELECTRICAL FROM BRAKE SYSTEM WITH IGNITION SWITCHED ON". now for those that are going to ask "how much?" new HBB is £1400+vat (non returnable to mitsu if its not the fault on pajero maybe on shogun) abs computer £544+vat.
lucky for me I knew where there was a crashed shogun and i got both bits for £270 cash.
