GD rear discs & pads - which ones are right?
« October 29, 2019, 16:03:37 »
My 2015 UK spec diesel hatchback has now done about 54000 miles, and I can see the rear pads are getting pretty thin. Does anyone know the part numbers for the genuine Hyundai discs and pads? The discs are 262mm diameter, and my car has 15" wheels. I understand that around 2015 Hyundai started fitting bigger 284mm discs with 16" wheels, and stopped offering 15" wheels because they were too small to fit around the larger brakes.  There are also options for cars with or without 'electronic handbrake'. My car has the hill start assist, which only works on really steep slopes, is that what they mean as 'electronic handbrake, or is that something different?

I'd like to get genuine Hyundai parts as the car is still in warranty

if you don't have access to the parts system, and you don't like to talk to your dealer (for obvious reasons) try messaging sgpetch on Ebay with your VIN and they should tell you the part number and their price.

In my experience if you are happy to wait a little while you can often find the genuine parts for maybe half price on ebay.

The discs do have the part number stamped in to them - wheel off to check.

Don't forget to lube the glide bolts while doing it (ceramic grease)

Looking at recent dealer health checks, the pads were pretty healthy not so long ago, they've got very thin quite quickly, so I suspect the caliper or glide pins have seized up. I don't know if this would be covered under the warranty. I phoned the dealer and they said it would if the original parts were faulty, but if a glide pin corrodes and seizes up, isn't that because the original seals and lubrication are inadequate?

When I phoned the dealer about a price for replacing the rear pads, they asked if I wanted prices for using genuine hyundai parts or non-genuine. I asked if using non-genuine parts invalidated the warranty and they said no, it wouldn't.

Dealer quote for replacing rear pads with hyundai pads is £140, for non-hyundai parts it's £124. Seems a lot when I can get Bendix discs and pads - which I think are pretty good - from my local motor factors for about £65.

As suggested, I tried SG Petch and whilst they gave me prices, they wouldn't give me the part numbers. Company policy, I guess they've got wise to people using them to get part numbers and then buying cheaper elsewhere. You're right about the brake disc part number stamped on the disc, it was illegible on the right-hand side, but when I looked on the other side, the disc is a lot cleaner.

Not sure this is the right page - but if not one of the others near it might help you check the part numbers

Splendid, thanks a lot. The Bendix parts I have are 521600 for the brake discs, and 510870 for the pads. One thing I've noticed though is that on the Hyundai pad, there is a pip in the middle of the back of the pad, is this intended to fit it in a hole in the face of the caliper piston, to stop it from rotating?

The Bendix pad doesn't have that pip.

Yes otherwise the handbrake won't work which will need resetting anyway. Was that number in that absurd list I put up?

Would you like me to quote it just one more time :mrgreen: I can't believe we end up with a part not in that list :snigger: :crazy2:
The list was meant to be in contrast to the "we don't supply numbers policy" :goodjob2:

In the UK it seems much harder now to get information and part numbers (without paying) than it was 10 years ago. They charge for HMAService access now. Many ads from dealers don't detail part numbers.

My local dealer is also now the bland corporate money making machine, not the helpful individuals it was then either, having been taken over by a chain.

if you ask them to look at a warranty repair you need to sign up to being charged £100 (187 AUD) or so if they cant find the fault.

The plot thickens. I took the Bendix pads back to the motor factors, who checked and confirmed the pads were the ones for my car. They went and fetched a box of Brembo pads and some budget pads, neither of these had the correct pip on the backplate. I got a refund but still trying to find the right pad from somewhere.

I guess you've noticed that lug is only on one  pad in each pair

Yes I did, on the inner pad that bears against the piston. I think I should be able to get Pagid or Brembo pads, which if the photos on the website are correct, should include the liner plates that clip into the brake yoke. That's a bonus.
