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.
