had my brake pipes replaced on my ST170 last week, and then the next day my clutch starts slipping, 1st thing I thought was possibly air in the system when the garage done the brakes, as clutch has only done 9000 miles from new, but my local garage refused to bleed the system as he said if there was air in the system it woudlnt cause slipping just car not going into gear easily,

But would rather second opinions. its a lot of money to spend if I really dont have too, tried googling but answers but its a minefield, so was hoping someone on here might know.

TIA
