Hello Dan, Thanks for your reply,got your instructions in the box actually,dad never mentioned they were in there, therefore managed it no problem,installed in 10 mins- no battery power this time,so saved a job. Done a test drive and was amazing difference,infact i had to brake that hard from around 100 mph,my bl**dy pad wear light is now on! Your costing me a fortune Dan! So on that note.. ive whacked it up to number seven,s*d the expense.
