I put my car on jackes the other day to rotate my tires. I found out with my hand brake up my rear driver side doesn't lock up (I could still spin it with the tire on..) whats the deal?? I looked on some website and it said that when jacking up the car sometime it messes up the brake line depending on where you place the jack so I checked and everything was normal.. so what could be the problem?? how to fix?

Also, I have to lift my hand brake really high to have it engage and I even follow the instructions on the Haynes manual to tighten the brake line.

 

I think you were probably reading www.motorvate.ca The potential problem is that the "arms" of a hydraulic hoist might squash the e-brake cable. It's not a concern with a little jack (<3 tons).
I had a simliar, if not exact, problem as you a month ago. My problem turned out to be a torn boot on the left e-brake cable. You should be able to inspect the condition of the boot if you remove your wheel.

There is a left & right e-brake cable. Each connects to a rear caliper. On the other end, both cables are hitched up to a "balancer". From there, another cable connects the balancer to the hand-brake lever. My left cable inside the jacket was seized up from dirt/crap that got inside through the torn boot. As a result, the left caliper was grabbing the rotor. I occasionally ran with a hot rotor which I could smell too. I ended changing the left e-brake cable altogether & had the brake lever re-adjusted. I had the Nissan dealership do the work.

I was warned that until I changed out the cable, I shouldn't tighten up the brake lever b/c it would only cause the caliper to grab the rotor even more which would really kill the rotor from excess heat.

Good luck with this!

 

How much did that cost you to take it to the dealership to fix??

 

Heh... Cdn$108 for cable, C$79 for installation with handbrake adjustment. Ouch!!!
