Cheers Panky for the offer but i do already have a copy of the manual.
Went out earlier this evening to collect the van, drove it round the industrial estate, broke hard and sure enough vehicle lurched sharply to the left, to be honest that was infact the first time it had happened to me.
when i get some free time i will jack-up the van and have a closer look at the brake setup and hopefully solve the problem
Being short staffed and working 12 hour day shifts will not help, the funny thing is my next planned day of is Oct 20th.
And we all know whats happening that day.
