Gidday just new to group and would like some advice please.
Have had two Isuzu diesels for last 15years and never really had any major problems with them, thats what I love about them.
Now started out with loosing power when engine warms up. Fine when engine cold?
New problem as failed WOF for brakes due to pedal going hard after a couple of applications. They blamed the vacume pump so I replaced the alternator/pump.
Arghh problem still there and cant seem to find any other vaume leaks. Also checked all brake calipers and slides for correct operation.
Got me stumped??
