Rear Brake Caliper Seizing | Parking Brake Issue

[Dezoris]

Rear Drivers Side Caliper or Parking Brake Sticking:

4 Symptoms of Problems

1. With traction control ON: The car has spun during aggressive turning or during an emergency maneuver. The car feels like the tail becomes overly unstable under braking and turning.

2. Straight line braking stability is effected, under hard braking the rear end of the car moves to the left.
This is safe to test for most drivers. Use caution, if in doubt take to your dealer ASAP. On a straight road if you are traveling 25-65 MPH and brake hard and feel like the rear end starts to move to the left or becomes extremely twitchy.

3. Brake Pad Odor.
If you are filling up the tank with fuel and notice a distinct smell every time, walk to the rear of the car and smell the rear left wheel to see if that scent becomes noticeably stronger.

4. Damage to the brake disk or bluish color brake disk.

If there is a noticeable groove and pad indentation forming on the rotor Or if there is bluish color to your brake disk you may have an issue or debris stuck in the rotor. Usually if you don't have the first 3 symptoms then you won't have this problem.

heaard the one.... I had one the wheels fell off.....I lost a CALIPER !
Just found the gripping limits of the V on a wet road!

keep us posted on what they say is causing this,..

[Dezoris]

The caliper is defective, the dealer is going to replace it however...
No parts in USA, and must be shipped from Korea. This was my fear about this car.

[Velo613]

WOW! That's unreal.

[zay9000]

would this have to do with the calipers being small with the heavy big wheels and hard braking.

[smellypanda]

something similar happened to a co-workers chevy. they repaired it 3 times and it failed each time so he got a new car out of it under the lemon law

NO, this is a 60/40 braking system....I had the same issues in my Tiburon, never this early though. You just replace the caliper, pads and if needed the rotors...

This sucks though it was so soon to see issues like this arise.

When they can replace this I would ask them to flush the brake system as well since it is getting hot for long periods of time it can cause the fluid to start breaking down prematurely. (Better to be safe than sorry in the long run)

I think I may have the same issue. I have always noticed an odd smell coming from the rear driver side wheel since day one. I thought it was just because it was a new car and the tires were getting wore in. I have had the car now for 3 months and about 3000kms and still smell it. I am gonna call the dealer today to get it checked out.

My wife will declare me certifiable if she sees me down on my knees sniffing my rear wheels. I have not noticed it while filling gas and we have vapor capture at the pump so it would be likely if it were the left rear brake. Wish me luck. Both during inspection and for what I (don't) find.

The car is still out of service, been 5 days no ETA.

The best way to test is to go about 50MPH and brake very hard in a straight line. If you feel the rear end get very loose/fish tail you have a sticky caliper. You should also smell it very easily walking around the car.

I asked about them doing the pads and rotors they said no of course. Also the fluid also was on my mind, although it's hard to say whether or not it reached a high enough temp to warrant flushing, but I will also ask they do it as long as they don't half ass it.

one thing I noticed with Hyundai Techs, or most techs for that matter is book time...they won't go the extra mile, because they will loose out with their bottom line...if they wont/don't just do it yourself and save the headache.

Its day 7 they got the parts. But want to keep to to test drive it more.
Regardless, I won't be bringing it back to that dealership for anything else.

It's less than an hour book time to replace a caliper. And a test drive should take less than 15 minutes. When I pick it up tomorrow I will complain.

[Dezoris]

8 Days out of service got it back today.

They only replaced the caliper not the pads or rotor. I was upset about that, however I told them I will pull the wheel and measure the pads for uniformity and the rotors if they are off it's coming back.

[xXcrookedHXx]

this is the one thing I diagree about warranty work...Hyundai pays the techs much less for each book hour performed on a service and they only want to do the bare minimum on the vehicle. Hopefully it didn't make too much of change while it was dragging.

[Dezoris]

Yeah I agree, I hope it did not warp the rotor.

Same problem with my Veloster at 9000km:

Check number 1: Place your car in neutral (or clutch in) on a slight decline/hill.
If your car resists rolling/does not roll: your caliper/s is likely sticking.

Check number 2: Engage your emergency brake.
If there is new or additional play or slack before you feel resistance (the pads engaging the rotors): your caliper/s is likely sticking. This will be your first indication: In my case I noticed this for 2 weeks before noticing the car not rolling freely. Reason: initially the caliper does not return to its spung, wide open position which causes the slack in the E-brake cable. At this point the pads are not in constant rotor contact - SEE YOUR DEALER AT THIS POINT - it will only get worse. Wet salty conditions accelerate this process.

Dealership fix in Canada: Hyundai Canada is now aware of the issue (no recall until enough cars have this problem)
The dealers are to fix or replace the calipers throughout the 5 yr warranty period. There is a back order for new parts so dealers are sending the calipers out to be serviced then installing the same ones back on your car. Only the faulty caliper will be serviced. They do not default to the rear pair.

Timing: 1-day for my dealership (401/Dixie Hyundai in Toronto) to resolve the problem.

Process: First, a Technician diagnoses/verifies the issue. A request is made to Hyundai Canada for a one day car rental under warranty (they respond in about 1-hr). They give approval, you are given the rental which you return the following day when your Veloster is ready for pick-up. I would immediately look into haveing warped rotors or heavily worn pads replaced under warranty although there are no signs of this at this point in my case.

Hope this information helps out some of my fellow Veloster owners!

I haven't noticed what you described in your first two checks, but I'm wondering if something is still wrong with my rear brakes. In the morning when I first start pulling out of my parking space, I hear a really loud clunk come from the rear of my car as well as some roll resistance. I would imagine that is the sound of the pads sticking or freezing to the rotors, finally letting go. However my car is parked in a heated underground garage so I doubt it could have froze.

I heard the sound happen several times but the brakes seem fine after so I didn't worry. It just really startles me when I heard it because it sounds like I just crashed into something even though the car only moved two inches.

My previous cars where automatic and I never used the parking brake in comparison, so would this be considered normal in winter time when there's salt and sand possibly seizing the piston? Would a technician be able to verify anything mechanically wrong if it just happens in the morning? I was planning on getting it checked on my next oil change, but I will go right away if it is causing damage.

[Toronto Veloster]

Hi Chuck,

(My Dealership is sending their shuttle to take me to my rental car - they have confirmed the work will be completed tomorrow afternoon)

The clunking sound is very likely the pads releasing from the rotors due to sticking calipers as you have guessed already. A heated garage can actually worsen this problem in fact. Warm salty water verses frozen/very cold salty ice/water will cause more corrosion to metal components. This being said, this should not be happening regardless of where you are parking your Veloster.

It sounds like adequate tolerances were not engineering into the metal caliper castings. As soon as there is some corrosion/oxidation there is no longer adequate clearance somewhere in the assembly... eh voila!

Go to your dealership right away Chuck - peace of mind is the worse case scenerio here!

Let us know how it goes!

Cheers! G

[Chuck]

Thanks, appreciate the input I'll setup an appointment in the next few days.
Wow, gonna be 9°C here in Toronto. It's been such a crazy winter, or lack of I should say.

Just discovered this forum !!

I had the same brake problem with my V, went to the dealership for a XM radio/antenna problem + rear break problem on last Jan. 28.
They took my car in, on Feb. 7 and gave me back my car Feb. 29. with new rear pad and disk.
( during the time they tried to repare the radio, they received my rear brake parts... took almost a month to get my car repair... but still have problem with the radio/XM/Bluetooth... this is another subject )

I had arround 12 000 km when realized my rear brake problem.

Now , handbrake is working well , brake are also working well on the back !!
