Do you normally change your own brake pads ?
If yes, then I'd have a go......if no, then I'd take it to a towbar joint..
Some cars are fairly straightforward but others require bumpers etc to come off, so unless you think you are capable of tackling it, pay the $100 and get it fitted....some towbar places are pretty reasonable with a all in price..
ps; don't go to a dealer...they charge an arm and a leg !!
