shreaded my girlfriends Quest emergency brakes
 

My girls got a 2004 Quest and I drove it for about ten miles with the emergency brake still on and now they barely function at all. I have decent mechanic skills replacing anything to do with the disc brakes on my Jeep, so although I'm not exactly sure what this will entail, I'm figuring I have a fighting chance of being able to fix this little situation myself.

So, I'm writing in to ask, exactly what is it I've damaged in the brake system and what parts will I need to replace to get the emergency brakes working properly again. I haven't had to get into drum brakes before but with some coaching I don't think it would be a problem.

Thanks ahead!

I can't figure out what really happen that causes it to break...

Look at the rear drums, you'll probably end up replacing them, the shoes and while you're at it, the hardware. If it got that hot the metal has been fatigued and may not be up to the job anymore.
