Here are the official online links for the repair and component location for your 08 Elantra Parking brake issues.

I would print these out and ask that you be allowed to observe the tech when he or she makes your adjustments.
 
Additionally, I would have them pull both of your rear rotors a let you see the wear on your parking/emergency brake pads (compare them to a new set, I could not find the specs on these), next have them check the round-out / run out of the rotors and the emergency brake area contact area.
 
HAVE THEM SHOW YOU THE SPECS IN THE REPAIR MANUAL.
 
IF Rear brake disc thickness (rotors) less than 8.4 mm ( 0.33 in), have them replace the rotors.
 
IF Rear brake disc round out /run out is greater than 0.05 mm (0.0020 in), this includes the parking brake contact area... tell them you want both rotors replaced, your car is NEW.
 
20k is about 44 lbs of pull force and your lever should come up 7 clicks. Ask to see the push/pull gauge they are going to use and when they can not produce it... tell them to go and buy a digital fish scale at Walmart to get the adjustment close and you'll be back in a week when they have the right tool...... Or better yet, just keep the loaner they give you until they prove they are following the procedures.
 
A really good push/pull gauge is only about $300.00 and they will probably have to order it.
 
Imagine if someone dropped the ball on a requirement for a torque wrench... these cars would be falling apart all over our highways.
 
Good Luck

Lastly the 20K of force should be 20Kg of force... which is equal to about 44 Lbs. of pull force.
 
The new 2009 Sonata procedures have the techs use a pull gauge during several step of the parking brake adjustments, with different pull force requirements... even used to establish a parking brake drag point on the rotors (then the parking brake shoes are backed off (shoe clearance).

Look at # 10 of the PARKING BRAKE SHOE (DISC BRAKE TYPE) Installation
 
look at # 3 of the Parking Brake Lever Stroke Adjustment
 
between the yellow-orange lines
 
Parking brake lever stroke :
7 clicks (Pull the lever with 20kg)
 
BIG NOTE IN GREEN under it :
 
After repairing the parking brake shoe, adjust the brake shoe clearance, and then adjust the parking brake lever stroke. (Refer to "Parking brake shoe installation")
 
and then the picture under this NOTE
 
Pull up with 196 N (20kg, 44lbs) force, within 38MM of the top ot the lever not to include the push button.
 
 
I'm off to enjoy the new years celebration, I hope you have a great one too.

I think many repair procedures rely on service techs knowing how to perform and understand general service procedures. I also believe, torque procedures and measurements, making thickness and clearance measurements, and performing pull / push measurements would fall into that category... Don't you?
 
Does someone else other that Hyundai write their Official Service/Repair manuals or maintain the Hyundai Motor America Service Web-page?
 
Whoever wrote the manual went to a lot of trouble to identify a certain pull force requirement, (put it in 3 different types of measurement force based on scale 196N/20 kg/44 lbs) identified a certain area position on the lever itself (within 38MM of the top of the lever not to include the push button) and how far the lever is to move from the non-set position (7 clicks).
 
If they did not want their techs to follow this ...I wonder why they go to so much trouble to include these measurements and a picture too in their manual?
 
You would think a Hyundai Field Engineer with a Hyundai Motor Representative and a Platinum Service Technician (all working together, on-site) would be able to breeze through these steps... THAT IS, IF THEY FOLLOW THE MANUAL AND HAD THE TOOLS ON HAND... RIGHT?
 
I'm in agreement with you, the manual could be a little more detailed, but this should not be used as an excuse on anyone's part, neither should skipping the procedures because they did not have the tool on hand.
 
I hope you have a spectacular 2009.

Just like you said, 196n/20Kg/44lbs. seems to be standard or at least a typical spec for Hyundais car with the pull type parking brake lever.
 
The "weak link" ... doing it by feel it not accurate... hence that's why there is a spec of 196N/20 Kg/44Lbs for these newer hyundai vehicles.
 
One techs feels right, might be over tight (MY CASE... BRAKE DRAG for 13 months)... while another techs feels right, might not be tight enough (AS I SUSPECT IN SCHUKANUOSLADY'S CASE AND MY CASE SINCE NOV 08)
 
Just out of curiosity, how many clicks do you have to raise your parking brake lever in order to hold your 04 Elantra... when you put your vehicle in drive, while at idle and let off the foot pedal brake (I assumed you have an automatic transmission)?
 
Thanks
