I'm planning on changing my front brake pads but it says I need a "large" C-Clamp. I don't have one of these and I don't want to take my wheel off to measure as this is a pain where I live.

I own a 1993 Civic LX and was wondering if anyone knew what size I need so I could just pick one up.

 

It's not that critical. If you get one that can open up to 6" that should be plenty big enough. In fact, you maybe don't need it at all. Sometimes I've been able to push the pistons in by hand.

 

A 4"-6" C-clamp will work fine.

 

You can pick up 6" one in any of the local auto parts stores. Also they sell the tool kit for front and back around $20. I've got one. Last time mechanic lost a bet to me when I've changed my front brakes for 17 minutes.
