2009 Grand Caravan SXT 3.8L brakes
 

My rear brakes are leaking brake fluid from the back of the brake caliper where the emergency brake connects. Will the caliper need to be replaced or is there a repair kit? This would be the rear left side. On the drivers side.

Check your local parts store for a rebuild kit.

Or just replace the caliper. It’s faster and easier, and if it fails then you have a warranty to replace it for free. The best you can hope for with a rebuild kit is getting another rebuild kit, and if it fails you have no one to blame but yourself.
